I finally got around to posting an update after installing the front upper arm kit and rear camber kit. After three technicians looked at the shims we opted not to install them.

Their product is well manufactured, a selling point for me is the amount of positive camber (for saving tire wear) they proclaim which they do live up to their specs. The rubber bushings on the upper control arms (same type as Nissan) for comfort, and that the dust cover for the ball joint covers the entire area (not like Kinetix).

The upper control installed nicely with a snug fit, well manufactured. We new up front that a metal flange on the underside wheel well would need to banged back for clearance of the outer arm where the ball joint is located. We also shaved about 1/8�of plastic (see pic) it’s all underneath and cannot be seen, **** I can hardly see it from the pic.

The rear camber kit took the longest, allot of time spent hogging out the toe slots on the frame. In the end we did not need to even install the toe bolts as the range to bring the toe back into spec again to save the tire wear, not for track setup. If so then I may want the toe bolt installed, but for getting the car back into spec we had enough with the original toe bolt, therefore only one of the two cars had the toe bolt installed. Camber arm is sweet and a fast install, which was needed with the rear spring at a 1.0� drop.

The results were amazing once dialed in on the alignment rack. The fronts we were able to go from a -1.4 on the Silverstone and -1.7 on the Interlagos Fire (IF) to -0.3 on both cars. Wow! We settled on close to nominal setting of -0.6 for both cars (save them tires). Our only problem was bringing the caster into range, we started out with arm set to dead zero, and by adjusting the caster on the arm would give up camber. So we set it on dead zero and achieved the -.06 camber. We are going back to the rack and adjust the caster on the arm and hopefully at least get the caster in the high range of at least 7.4. with a camber of -.08. It’s about all we ask can for.

As far as the ride, I could tell right away that the car felt like the tires were planted more firmly. Braking in a dead straight line, the car did not pull at all, braking in corners was solid. Cornering, well let’s just say that I feel more confident taking corners a bit faster. Overall I am very pleased with my current suspension setup. Next mod, SWAYS, hopefully I will not give up that comfort with the sways (at least not allot). My choice would be Hotchkis.
