I bought a Sears digital torpedo level to double check the actual rear camber settings, I found that I had -2.3 degrees on the drivers side rear and -2.1 degrees on the passenger side rear. Way too much!
I set Ben's adjustable length link to be the same length as the factory unit, making sure to keep the threaded adjuster section centered. I also used anti-seize on the threads. My unit from Ben was a convertible core and I have a coupe. The only different between the two units is the the convertible link has a larger OD (34mm vs 30mm) ends with a correspondingly thick rubber bushings. The larger diameter end did not cause any fitment issues on the coupe - mine is a S5 if that matters. Once installed I then shortening the length from 284.0mm CL to 266.5mm CL (about 11/16"). I measured the distance between the locking nuts to track the reduction in CL length. That was about as much as I felt comfortable with since the clearances between a lot of things was getting marginal. As a note I have stock rubber SF bushings. After a short ride around the block to resettle the suspension, I was able to measure a reduction of 1.1 degrees of negative chamber on both rear wheels. Amazing!
I then took the car for a longer test drive and the only way to describe the change was as if you had removed a few hundred pounds from the trunk. If feels that much improved. I even double checked the ride height and it did not change. The car feels more solid with the front and rear suspensions not fighting each other - the car reacts more as a whole unit now. I had not realized how sensitive the FC chassis is to changes in rear camber, but it must have a big impact on how well a semi trailing arm rear suspension works and feels.
Thanks again Ben for a great product at a great price.
