November, 2015 update: This article is growing old, and while the information here is valid and important still, we encourage you to visit our latest writing on this Ingalls vs SPC camber kit matter: Honda/Acura Ingalls vs SPC Rear-Camber Kit Debate: 2015 Update
September, 2016 update: Announcing The New Ingalls 38727 Spherical Adjustable Camber & Toe Kit
I had a customer in today, 05 TSX with some Tein Basics set at a 13.5â€³ height all around (measured from center of center cap to fender lips). The camber in the rear was corrected with an SPC camber kit, also sold under the CT or Comptech name.
Some of you know from reading our posts and such over the years that we recommend the Ingalls brand of camber kits for the rear on a TSX/TL/CL/Accord. And this post is to tell you why.
Because the arms mentioned, in addition to those sold by Megan Racing and Eibach, all replace the upper arm in the rear to an adjustable part. The rear upper arm that these kits replace on these cars contains a ball-joint to attach it to the rear hub carrier.

The problem with replacing the stock arm with an aftermarket one is that the stock ball-joints have really high quality rubber on the boots, and are deigned to work within a specific range of motion. Because aftermarket ball-joint boots are of inferior material, and are subjected to altered range of motion (when installed on a lowered car), the boots tend to become brittle and they brake after a while.

It is for this reason we will mostly recommend the Ingalls camber kit for these rear multi-link applications. The rear Ingalls kit is a set of 2 arms per side, which replace lower links in the suspension, 4 arms in total between the left rear and right rear.

- There are many benefits of this kit over the ball-joint type kits mentioned above:
- Camber has plenty of adjustment range.
- The bottom of the wheel is pulled in, rather than pushing the top out (can give more fender clearance for lower offset wheel fitments or wider tires).
- No ball joints mean they will last much longer than the other kits.
- Easier access for the alignment shop to adjust
- Easier to install, since ball-joints can be a bear to remove at times.
So, that is why Ingalls rear camber kits are the #1 recommended rear camber kit on rear multi-link Honda and Acuras. They are HT-Spec!
Donâ€™t believe me? We had another customer in this afternoon for an Ultra Racing Rear Lower Brace test fit (works perfect with a CT exhaust BTW). This particular customer was running a set of Tein Super Street dampers and Ingalls 38725s on his â€˜04 TSX with OVER 150,000 MILES!

Still in perfect condition!
In summation, replacing factory ball joints is undesirable, so if at all possible, go for the part that avoids doing so.
