The guys are right, the front camber should only be 1 - 1.5 negative which can be gotten with the shorter springs and adjustable pearch.

You should replace the front radius rod bushings (which I happen to have in stock) and the lower control arm bushings should be replaced (I have those also).

However I believe to make the cars really handle well you should focus on getting more rear camber (up to 3 - 3.5 neg.) it will make the car less twichy, and with a good set of upper control arm bushings (which I also have) you can adjust the camber for the track (less for pocono, more for NHIS etc) with simple shims.

Getting a much rubber out of the control arms makes the car more predictable which will lead to consistant handling which will result in driver confidence which will result in lower lap times which will result in a happy camper with more trophys...
