Alignment question (Track relevant)
I recently added camber to my car to get to -3 front and -2.5 rear to try and reduce tire edge wear on track on the stock wheels and stock cup 2's (toe links F/R and castor bushings front). Fronts work well - no problem.
However, I see that the outside edge of my rear tires are now slightly rubbing on the inside edge of the fender. They did not rub at -2.0. My assumption is that by adding the additional shims on the control arm they pushed the wheels out a small bit, but enough to now just touch the fender inside edge under compression.
Front tire wear looks much better at -3.
Now, my question is how important is it to maintain the 0.5 difference between the front and the rear. Reason is that if there is room for play, I'd like to back off the camber in the back to -2.25 or the old -2.0 to see if I can solve the rubbing, but that would leave a 0.75 diff between front and rear?

Came by garage 17 and we can do a pyrometer check. A little bit of rubbing is fine.

The GT4 is fast - as fast as my .2RS at TWS, and faster than Lally in a RS 
Purple = Lally in a .2RS - R6
Blue - GT4 - R7
Red - .2RS - Pirelli DH

Ahh, missed that one!
Nice driving! Amazing it's as fast as a 2RS given the power advantage.
Did you go with more negative camber this time out?
