I don't own a pyrometer yet. Plus, my camber is fixed in place with solid blocks so I can't change it unless I put a new block in. I can decrease it by shimming out the upper A-arm though. Right now I'm running 2.7 in th LF and about 2.6 in the RF as of my last allignment.
I'm not sure more camber will help... I think it's a function of running a 255/35 tire on a 10.5" wheel with a 2900lb car on top of it; only the LF had issues.
Since I'm caging the car now the weight etc will all change so I'm going to have to re-set the car. I may install camber blocks to push the LCA out even further, but then shim the upper A-arm to get the desired camber. That way I can add in more at the track if I need to.
If I'd had more time I would have possibly tried more rear bar, but the car felt good enough to win and I didn't want to waste a session trying something different. I haven't run the 255/aero setup enough to start to changing setups. Plus I was instructing and the weather was crazy so I didn't have a ton of free time. VIR's paddock is gravel and it was 38 degrees so I didn't feel like rolling around in cold gravely mud
Once I slowed my entry into T1 and Rollercoaster I was ok, but it can be better and I will tweak more when I get it out at Road Atlanta again in June.
