TEIN Suspension STREET ADVANCE Z SAZ Coilover-Damper Kit, Acura TL 2009-14 (ALL), GSB96-9USS2

The Tein Street Advance Z is a kit evolved from the Street Advance (SA) and Super Street (SS) kit, which itself was an evolved design from an earlier iteration. With it, they widened the dampening range to appeal to a broader audience, added corrosion resistance to the threaded section, and improved the bump-stops to improve longevity. Tein continues to develop their product line which is what makes them a leader in today's very crowded coil-over damper market segment. The only major design change with the SAZ over the SA is that the SAZ is not a re-buildable or servicable damper tube. Meaning, you can't send it in to Tein for custom valving or repair. Failures with Tein dampers are extremely rare and in the event a damper should fail or be damaged, replacement tubes are available at a reasonable cost.

The Tein Street Advance Z Damper kit is the bread-and-butter of the Tein product line. Most users looking for a spring and damper combination that offers both a compliant street ride as well as enhanced sporting for improved handling will find that the Tein Street Advance Z (often referred to as the SAZ) checks all the right boxes. Combined with springs that are conservatively chosen for increased cornering loads and management of weight transition, and adjustable damper tuning centered around tigher high-speed and moderate low-speed damping, you have a suspension system designed for the masses.

The lowering range for this single-length adjustable kit is moderate as well, being adjusted with threaded collars and spring seats. One should expect a drop that is noticeable and gives the car an aggressive stance. When adjusted within it's recommended range of 1.5" to 2.25" lower than stock, the daily usability of the car with sufficient ground clearance for most obstacles is excellent. If someone is looking for a suspension that will totally-slam their car then look to a kit with full-length adjustment, such as the STREET FLEX SF . Contact Heeltoe for consultation if you are not sure!

More on the adjustment of the height...Tein offers some of the industry's finest spring seats and locking collars. They feature flanges that prevent the wrenches from falling off the collars as you are turning. And those wrenches...some of the longest in the industry, and an ergonomic shape, which allow users get the most torque for easier adjustments. Lastly, a thin, delrin spring seat washer enables the lower seat to spin freely against the bottom of the spring. (Unless you've handled a suspension kit like this before, some of the features just mentioned may not mean much...but we promise, you'll appreciate that Tein thinks as much about the tuner as they do the tuning.)

To ensure that people are able to achieve the ride and handling balance that is to their liking, Tein provides dampening valve adjustment. 16 distinct settings (or up to 32 with EDFC installation) allow user to dial in click-perfect balance. These settings can throw off the handling of a car, but Tein's limited range and high-quality "click assemblies" take some of the pain ouf of adjusting. The clicks mostly control the rebound rate, which when slowed down enables a higher level of performance at the expense of slower response over bumps (and a little rougher ride).

Customer Questions


What the difference in to base bushings and to base bushings with assembly?


The "assembly" option means we will open up the upper mounts and put them together (there are many parts involved) and install them onto the Tein damper. We'll torque the top nut properly and preset the height to the recommended baseline setting.

With this option you will not need a spring compressor or use of an impact wrench to tighten the top nut, saving you installation time!


just to clarify, this kit does include both front and rear correct?


Correct, this kit comes with dampers and springs for all four corners.


Do any of the edfc kits include the motors?


To get an EDFC on the car you will be getting a motor kit as well as a controller kit of your choice. Choose between the EDFC II, EDFC Active, or EDFC Active Pro.

Q:What is an FLP tower brace and why is it for edfc installed?

A Fastline Performance Tower brace is offered because in order to easily adjust the front dampers or install an EDFC you need to remove the factory tower brace. This brace replaces the factory one and allows full access to the dampening adjustment.: Fastline Performance Solid Tower Brace, Black, 2004-08 Acura TL & TL-S UA6 UA7 (EDFC Compatible)


Do we need a top hat kit for an 04?


The upper mount kit from the factory dampers can be reused, but we do offer an option to get an upper mount set from us to make the install easier.


What is the difference between the base top hat and the rigid type s ones? Would I be able to use the type s ones in my 05 base TL ?


The difference is in the bushings. The Type-S ones have a metal washer galvanized in them that firms them up quite a lot. You can use TL-S bushings on a Base TL and this will provide a little better damper response and road feel.

Q:What is the full drop range?

This system will lower to a max of 2.25" below stock on a 3rd gen TL.

Q:What's the difference between EDFC II, EDFC Active, or EDFC Active Pro?

For more on the EDFC and differences between the models, see this link: Tein's EDFC: What Is It, Why Get It, & How To Order

Q:What is the difference between the advanced and the TIEN Basis Z?

The Street Basis Z and Street Advance Z kits are really the same except the Street Advance Z has an adjustment knob on the top of the damper where you can adjust the ride feeling and handling characteristics of the suspension.

Q:Would these be a direct fit for '07 TL-S? Do I need to buy anything additional like top hat or camber kit? I would prefer these over basis for damper options.

Yes, this coilover kit will fit all 2004-08 TL models. The top hats and camber kits are options we offer, but neither are required to install this kit. Contact us to learn more about these options!

Q:When you assemble top hat, do you also set preload ?

Yes we do. We set it to Tein's recommended height, where you can further adjust to your desire.
