I took race car vehicle dynamics I and II and I still don’t see the relevance of changing the control arm’s length, especially seeing how he lowered a car with SLA ~1.5 inches. The stock control arms are not at any extreme angles, and the change in height only changes the angle minutely. The control arms are now statically more along their camber curve, which is good. If adjusted properly a stock C5 can achieve a camber of -1.2/-1.5 front and -.8/-.9 rear.
I’m saying over all, the best bet to increase traction would be to adjust his camber to the max, possibly get the rear camber plates to obtain -1.2 in front and rear, and buy a more sticky tire. I don’t even think anyone makes a different length control arm for the c5…I maybe wrong on that though.
Question: How much shorter would you make them? And what one would you decrease the length of? I could be entirely wrong, so enlighten me on the subject!
