Racingbrake: Blow Acuras Away With Standard Open-Slots!

Tuesday, October 5th, 2010

Who has heard of Racingbrake’s latest innovation: Open Slots? This really inventive concept was first introduced on their super-high-end rotor offerings for NSXs and Corvettes, and now is becoming standard on all Acura 2-piece rotors and the newest 1-piece rotor for the Brembo-equipped TLs!

See this link to learn about the THREE big patented advancements made in rotor design available for your Acura TODAY! When it comes to making rotors, there is no better OE replacement part available!

We have updated all our 2-piece rotor descriptions (we tried anyway, there are so many of them between “Build My Own Brakes” Combos, HT-Spec Staged Brake kits, and individual listings…let us know if something is wrong!) to reflect the new Open-Slot finish.

HT-Spec TSX gets new rollers…Steam-rollers from 949Racing and Hankook to be specific.

Thursday, September 23rd, 2010

After months and months of waiting for the first batch of 949Racing 6ULR wheels to come in, and more months and months of deciding which tire and which color to option, and more months of trying to sell the Mugen M5 wheels I’ve been running while waiting…I have finally installed the first signature set of HT-Spec Wheels/Tire package on the HT-Spec Project TSX!

What makes this package HT-Spec? Specifically, the sizing. When it comes to choosing wheels, there a lot of different camps on how to do it “right.” Some prefer wheels 50% wider than stock with tires that are 10% narrower than stock. Some prefer to run whatever used JDM wheel that fits “pretty good” without fender rolling. Some want to keep the original size. I am with the camp that feels the widest tire possible on a wheel that provides a square sidewall and perfect backspacing is best. An people that share this opinion have a hero. His name is Emilio, and he runs a wheel company called 949Racing.

949Racing has made a huge splash in the track-performance world by introducing wheels with specs that mainstream manufacturers don’t dare to touch. Starting out with 15″ wheels on Miatas made his name, but left folks with larger wheels wanting something more. When he announced a 17″ product I instantly became elated. The 17″ wheel, dubbed the 6URL, was actually developed for the S2000 market. But as luck would have it, the 17×9 version on a 48 mm offset ended up being a perfect fit on out HT-Spec TSX, even when lowered significantly with an HT-Spec Damper Kit!

We test fitted a set back in May and posted the results on our Facebook page. With a 255/40-17 tire, which is slightly smaller overall diameter than the stock 215/50-17 size, we found the rubbing to be minimal with our HT-Spec Damper Kit set to a 1.75″ drop, and non-existent at a 1.5″ drop or with a very slight roll to the fender in the rear! The front required only a removal of the fender liner clip and no rolling needed at all. There is hardly any clearance on the insides, but the front wheels/tires do not rub ANYWHERE on the inboard side, even at full lock in a loaded U-turn!

The tire we chose for this package was a Hankook Ventus V12 evo K110. This tire has gotten a lot of great press, most notably in the last Car & Driver tire shootout, where it came in a close second to a much more expensive Michelin PS2. Check the link for details on this tire. The excellent rating and bargain pricing were all it took to convince me this was the tire to go for. Optionally the Hankook Ventus R-S3 would be the tire to get for track performance. The high level of grip makes it a performance champ, but the softer compound wears fast on the street. We might get a second set with the R-S3s, but for now the V12 evos are definitely the way to go!

Truly this is the MOST tire you can get on a TSX without fender modifications*! That is how this wheel and tire combo got to be HT-Spec! Healthy sidewalls = stock-like comfort. Wide tires = macho grip. Perfectly fitted wheels = Minimal-to-no rub.

* You’ll note we are running camber on this car. In the images the rear camber is natural and un-modified and comes purely from the lowered ride. We are planning to install an Ingalls Camber Kit and bring it to an even 2.0 degrees. We will need to roll the rear fender about 1/4″, which is almost nothing. The front camber in these images is displaying about 1 degree negative as achieved with Skunk2 Pro Series Front Camber Arms. We will be dialing in about 1.5 to 2.0 degrees negative up front as well. For information on camber and the effect it has in improving performance, read here.

I've been rolling on these 17x7 M5s for a while. They are nice and all. But not really turning me on.

Oooo, wheels and tires mounted...getting nervous.

949Racing Luggies and hub rings are ready. We'll use the purple rings. The golds were on hand just in case we had the size wrong.

949Racing Luggies. Very light aluminum, and unlike most other racing nuts, these are fully threaded.

A little weight comparo. Mugen M5, 17x7, +48 with a 215/50-17 is 45.8 lbs.

An HT-Spec 949Racing 6ULR (size 17x9 +48) with a 255/40-17 tire weighs 43.7 lbs! 2 lb savings per corner for 40+ mm in tire? YES PLEASE!

Here is a little visual comparison of how much rubber we are actually adding.

Something like 8.5 inches on a 215...

...and 9.75 inches or so on our new 255. Yikes!

Front hub ring installed and ready for wheel (ooo, Racingbrake 2-piece rotors are the centerpiece of the HT-Spec Stage 3 Brake Kit).

Rear hub ring installed and ready for wheel (note fancy HT-Spec Damper, Chassis Brace Kit, and Brake Package items. Who can see the HT-Spec item that is MISSING from this picture?).

And without further ado, installed pics!

At long last! A TSX Rear BBK with an upgraded caliper and reasonable cost!

Wednesday, September 15th, 2010

Fastbrakes has finally completed their rear big brake kit for the TSX using Wilwood E-Brake Calipers and a massive 12.2″ two-piece rotor! The benefit of this kit over stock is increased brake torque through greater clamping force on the pads and a greater moment from the bigger diameter.

Fastbrakes rear bbk for TSX

The pictured rotor has slots and dimples but the supplied rotor has slots and drills. The performance of this kit is probably best matched to one of Fastbrakes’ front 2-piece kits with either 4-pot or 6-pot calipers. Look for a Stage 4 HT-Spec kit with these products supplied in comprehensive combo packages really soon!

HT-Spec Brake Pad Bed-in Procedure, recommended by Heeltoe on all HT-Spec braking systems.

Thursday, August 5th, 2010

First it is important to know what pads you have, and what they are capable of. Heeltoe Automotive recommends Racingbrake or Hawk Racing pads, which offer different levels of performance depending on your needs. Find out more about the differences in pads under product descriptions on Heeltoeauto.com!  
 

Alert:

 
Bed in is not a one-time thing. If you overheat the brakes or use them irregularly they can “un-bed” as it were and the friction surface is not ideal. It can manifest itself with noise, glazing, shaking….you need to go out and re-bed the brakes. Sometimes you need more aggressive pads to get it done!
 
 
 
The following bed-in procedure is drawn from our personal experience in breaking in pads, and from technical information gathered from the Racingbrake Website.
 
All brake pads must be bedded-in with the rotor they will be used against. Even though those performance street pads have been burnished at the factory, a transfer film must be generated at the pad and rotor interface for optimal performance. Whether it is new or used rotors, you must follow the bed-in steps listed below to maximize brake performance.
 
STREET PADS, example Racingbrake ET300/500,  Hawk HPS, Ceramic, and HP+
 

  • After installing new brake pads, confirm pedal pressure before driving car. On an open road with no traffic, make 6-10 heavy slow-downs, NOT complete stops, from 30-10 mph then fast
    accelleration and repeat with increasing pedal effort/brake effort each time until just shy of ABS activation. The idea is to heat and maintain that heat in the pads and rotors during the
    procedure.  
  • On an open road with no traffic, make an additional 2 to 3 hard slows from approximately 45 mph to 5 mph applying firm pressure.Do not drag brakes or come to a complete stop. Engagement of ABS or threshold braking is not required.
  • Now, gradually building heat into the brakes, I like to run up to about 80 and bring the car down to about 40 mph in a short distance with heavy pedal pressure. Do this 2-3 times. You may experience some fading if your brake fluid is not upgraded and you have stock brake lines.
  • Allow 15 minutes for brake system to cool down by cruising at normal speeds.

 
Do not sand or grind the brake pads or rotors after this burnishing procedure has been completed. Your performance street pads are now ready for driving! I generally recommend to drive the car normally from here on out. I do not recommend using the brakes as a way to slow the car down, but rather use them as a way to CHANGE SPEEDS to a lower one. Keeping this thought in mind while braking will prevent you from making long gradual stops that raise brake temperatures above the desired level for street pads. When street pads get too hot, they can glaze the rotor surface or put inconsistent pads deposits on the rotor which will cause a shimmy.
 
Also, be aware that Racingbrake rotors have a special metallurgy that may require up to 500 street miles before break-in is achieved. You will need to get these rotors HOT! If there are not plumes of smoke billowing from new Racingbrakes you probably did not get them hot enough.
 
Lastly, do your best not to engage the ABS system within at least 300-500 miles of bed-in. If a shimmy should develop, one should reapply the bed-in procedure listed above.
 
 
! Added 6/8/10 !
 
You will know your brakes are bedded correctly when they look smooth without much or any trace of the factory’s cross hatched finish.
These Racingbrake 2-Piece rotors were returned to us because the customer was having a shimmy problem. We saw as soon as we opened the package we noticed that they had not been bedded properly. Even with ET500 pads the bedding was not aggressive enough to take down the cross hatching.

 
The same rotors as above after being bedded properly. I took the returned rotors and put them on the HT-Spec TSX. Some initial shimmy was noticed until heat was built up and pedal pressure increased. All shaking prompt went away ad has not returned in months of mixed driving. It is not the greatest image, but you can see the cross hatching is gone after one bedding session.

 
 
If you hear a noise after bedding that sounds like the brakes are dragging a little, this is relatively common. As your brakes wear in this noise will go away or at least will get very faint.
 
If you are looking at the not-bedded image above and notice that dimple in the rotor face, it is also normal. This dimple is evidence that the rotors have been hardness tested to ensure quality control. The dimple is deep an will not go away, and it does not hurt anything. If anything, be glad it is there, since no other brake companies really seem to care enough about their products to test their hardness before shipping them!

 
 
 
 
 
 
RACE PADS, example Racingbrake ET700/800, Hawk Blue or other Motorsports Pad
 
Prospective racers are cautioned that unless these racing pads are properly bedded-in at race track conditions it can result in pre-mature failure or ill effect.
 

  • Seal all brake ducts if any.
  • Slowly engage brakes 6 to 8 times at medium speeds (60 – 80 mph).  Do not drag brakes or come to a complete stop.
  • Increase speeds to simulate race conditions; allow 6 to 8 high pressure (about 500 psi) snubs at racing speed. Total engagements for Step 2 should be a maximum of 15 to 20.
  • Remove brake duct seals.  Allow the system to cool for about 15 minutes.  Do not engage brakes while car is parked during cool down period.

 
Do not sand or grind the brake pads or rotors after this burnishing procedure has been completed. Your motorsports pads are now ready for race!

HT-Spec Brake Packages: Mending Your Honda/Acura’s Achilles Heel

Thursday, July 8th, 2010

As great as Honda and Acura cars are, it seems pretty consistent for drivers to complain about their braking performance. If not the performance itself, but the life and consistency of the braking. We have spent countless hours in the forums and on the phone consulting people and helping them find braking solutions that will meet their needs. For a long period of time we were marketing order pages where people could build their own braking packages to suit their needs. Over the years, we have seen many kits being ordered over and over again, and we have taken these particular kits and built packages out of them to remove any and all guess-work out of the purchasing of a brake kit. With the introduction of HT-Spec Brake Packages, we hope you will find enough information here and on the order pages to show you that your hunt for brakes to suit your needs is over!


Stage 0: Standard-Plus


By far the number one complaint we get is with regard to shaking in the steering wheel. Many people falsely assume this is a warping problem, although our experience has told us that it is largely caused by an inadequacy of the brake pads to cope with slightly higher temperatures than normal. We have written extensively on this subject, and you may access our documentation here. Our general feeling is that, in order to get consistent, smooth, and reliable braking out of your Honda/Acura it needs a significant change in brake pad compound. The Stage 0 Brake Packages are dubbed “Standard-Plus,” which is intended to give you a sense that these packages will take your standard brakes and up the performance and economy to a level that you’d expect from the factory. It is a shame that Honda is unable to produce a brake pad that is able to stop smoothly, confidently and quietly without producing excess dust. Stage 0 Brake Packages do just this.

HT-Spec Stage 0 Brake Kit, Now Available For 04-08 Acura TSX and TL! Choose between RB ET300 Pads or Hawk Ceramic Pads


You’ll notice that ALL HT-Spec Brake Packages include Fastline Performance Stainless Braided Brake Lines and new brake fluid. The idea behind this is to highly encourage people to increase the frequency that they change their fluid. Honda only recommends a change every 3 years irregardless of mileage. We are sure this is a reasonably safe interval, but in that time braking performance degrades significantly. More frequent changes, in conjunction with brake lines that will not expand or deteriorate, will help your brake pedal feel firmer, confidence inspiring, and consistent for the life of your car.


Stage 1: Street Enhanced


Stage 1 Brake Packages up the ante by including a front brake rotor upgrade. This “Street Enhanced” kit includes a set of rotors most chosen by our customers: The Racingbrake UP 1-Piece front rotor. Racingbrake rotors have been a favorite of HeelToe’s for the last 5 years and counting. We have written extensively on the benefits of Racingbrake UP rotors, and you may link here to read up some more on them. Strictly speaking, if you are not going to get Racingbrake rotors, we would just as soon recommend keeping the rotors stock, or simply buying the cheapest rotors possible. None others match the functionality of longer life and cooler performance than Racingbrake offers and to pay for marketing bullet-points that don’t include engineered alloys, curved cooling vanes and reinforced hubs is simply a waste of money! Racingbrake ET300 pads compliment the UP rotors, as they are formulated to mate well and perform flawlessly with the UP rotors in normal or sporty street driving while producing extremely low dust and no noise to speak of. At this stage, rear rotors are optional, as a frontward brake bias does not cause much of a benefit to upgrading the rear rotor beyond appearance.

Stage 2: Sport Package


For the serious street performance driver, HeelToe is proud to introduce the Stage 2 Brake Package; The “Sport Package” that the A-Spec cars SHOULD have come with. Building on Stage 1, the Stage 2 Brake Package increases the braking performance of the car dramatically by increasing the brake pad compound to an aggressive street spec. Racingbrake’s ET500 brake pad is a phenomenal street performance pad that is tractable enough to be used in cold morning weather, yet has a high enough temperature rating that it can be used for light track duty. You won’t find a rotor and pad combination that provides a better balance between performance, long life, low dust and noise at any cost. The brake fluid supplied with the Stage 2 Brake Package is upgraded from Honda OEM to Motul RBF600. This DOT 4 level fluid that offers a higher boiling point than standard DOT 3 fluid to resist boiling under extreme use. We haven’t seen a better value in temperature rating versus cost, so the Motul RBF600 is our choice for high end street and entry level track performance! Rear rotors are still optional here for street use, but we do recommend track use cars upgrade the rear rotors as Racingbrake’s engineered alloys will help extend rotor life and balance braking.

Stage 3: Performance Package


For the ultimate braking package using the stock brake calipers, look no further than the HT-Spec Stage 3 Brake Package. We have dubbed this kit the “Performance Package” since it provides a massive improvement over stock. The addition of 2-piece rotors to the kit and aggressive ET500 or ET800 pad options make this a highly track-worthy kit. The benefits of 2-Piece rotors are huge (we go into detail in this link; highly efficient cooling, forged aluminum hats for strength; curved cooling vanes; highly upgraded alloyed iron material extends life even with track pads; weight savings of over 10 lbs off the front axle. The Stage 3 Brake Package will make your tires strain for traction lap after lap!

More stages will come later offering larger rotor diameters. But for 90% of us, we feel than the Stage 0-3 options will fit the bill for all your Acura’s braking needs!

Weights & Measures: How Much Unsprung Weight Does A Racingbrake 2-Piece Rotor Save?

Tuesday, June 29th, 2010

Let the images do the talking. These rotors are all from a 04-08 TSX. First, an OEM Rotor. This rotor comes in at 17.8 lbs:

17.8 lbs for a stock TSX front rotor, with minimal wear. Rotor is not near the service limit.

Now, a Racingbrake 1-piece UP rotor for the same application. There is some added weight added coming in at 18.3 lbs with this rotor since it is a bit thicker than the standard rotor, and has more material in the hub area which is greatly reinforced versus the stock rotor :

Racingbrake UP 1-Piece Front Rotor, 18.3 lbs.

The 2-Piece rotor from Racingbrake, featuring a forged and CNCed aluminum hat, free-floating, center-mount design, and G3500 racing alloy material, weights in at a paltry 12.7 lbs per side! This is a 5.1 lb savings per corner versus the stock rotor, and 10.2 lbs of the whole front axle!:

Racingbrake 2-Piece Rotor for TSX Weighs 12.7 lbs!

With the ability to stand up to street- and track- duty pads, light weight for better acceleration and suspension action, and reasonably priced replacement rings, the Racingbrake 2-Piece Rotor is a definite winner for street performance and track-day enthusiasts. And if you are for show, you simply cannot beat the look for the cost.

Is it any wonder we chose these rotors for our HT-Spec Stage 3 Performance Brake Packages and for our HT-Spec TSX Project Build?

Racingbrake Rotors Break The Mold: The Best Rotors EVAR!!! So awesome, they are HT-SPEC!

Wednesday, June 16th, 2010

It is no secret that Raingbrake performance brake rotor have been a favorite of ours for the last 5+ years. We have been writing and posting about them for years, and have converted many of you into believers in Racingbrake’s technology. We would like to take a little time to look back at some of the information we’ve published to help inform the many newcomers to the Acura scene.

I have also gone through and added some footnotes to bring the writings “up to date.” I learn things over time, as do we all. Note updated writings referenced by the “! Added _/_/_ !” designation.

Let’s start with this article that does a decent job of outlining how brakes work and what can cause the shakes and shimmies we all dread so much:
Heeltoe’s Take on Brakes; Some general comments.
08/03/07 – Not much updated but still good to read and freshen up!

In this article, I outline some factors concerning brake rotors and pads. One of the main talking points has to do with shimmying, or the shaking in the steering wheel you get while braking. I also comment on driving technique, which probably influences the condition of the brakes more than you think it would…and differently than you think it would as well!

Racingbrake UP Rotor next to a stock 04-08 TSX Rotor. Forget the slots...read our articles to see what really makes these rotors awesome.

A technical article that a lot of people bought Racingbrake product based on, and one that I am sure will resonate with some folks out there who are looking for a rotor that is a TRUE upgrade:
Why Racingbrake is a great brake rotor
08/15/07 – Updated with new pics and commentary!

This article is sort of a continuation on the one above. In discussing a lot of the issues with brakes, I can build a really good case for how Racingbrake overcomes these issues with features that go beyond what the competition offers (namely, holes and paint).

Then here is an informative posting I made was with regard to brake bedding, now with pics added!
Brake Pad Bed-in Procedure, recommended by Heeltoe
07/12/07 – Updated with new pics and commentary!

This gets it’s own article because of how important it is to get right. I have had a few customers buy Racingbrake rotors, even 2-piece ones, and complain of a shaking a few months after they install them. We take them back for inspection and upon inspection we notice that the rotors have gotten warm, but the cross-hatching in the friction surface of the rotor is all there still. The cross hatching is designed to promote bedding by increasing the friction of the surface causing the pad material to heat up faster and fill the crevices of the rotor face. Racingbrakes in particular MUST have a high heat buildup in order to be bedded correctly. If the cross hatching is still very obvious after bedding in, you did not get the part hot enough. You should see smoke after bedding new Racingbrake parts in.

Once you have your rotors on, let’s see how long you can get them to last!
Racingbrake UP rotors up to 3 sets of pads in 5 years with over 60,000 miles…not machined once.

We are excited to sponsor new projects that will tap Racingbrake’s knowledge in order to create the best braking systems out there!
An article from Counterman Magazine (yes, I get this and read it monthly…it’s my life I guess): Signs Of A Good Rotor: Proper Design, Build

So, in this posting, I have taken you on a sort of technical journey. First, I have explained a little bit about braking systems. Then I went into great detail on why it is Racingbrake rotors are superior to the competition. And then I have noted that when you have made the wise decision to purchase and install Racingbrake parts, you get them bedded in properly.

Thanks for reading! If you have any questions at all, I encourage you to call or email me; or better yet, post up here for all to read and learn from our discussion!
