For those who have clearance issues, how much negative camber are you running?

I just bolted on a set of R7s and am scheduled for a 2 day DE next week on a track with banked corners. They are noticeably wider. I ran square Kuhmos last year and had rubbing on the fronts and am thinking I'll get a different set of tires for this track. Would be awful if I can't run.

Wow, this thread is growing with the issue of the squarer shoulder shape of the R7. You'll see in my earlier post I raised couple comments. Well I just eliminated the tire rub issues with a few adjustments. Ride height and camber I have learned are key variables. I have installed R7 245/40-18 and 315/30-18. I was expecting the rear to be an issue... no problem. The front I ran BFG 245/40 and no rub issues. Now the R7 245/40 and definite unacceptable rubbing. I had rolled the fender well some but the contact was near the side marker light not rolled. I rolled the fender another inch or so. Then raised the ride in the front about 10 mm. Camber is not heavy track but only 2.8 negative. Now I have no tire wheel well contact and actually can start dialing down the ride height.... I think about 5 mm will bring back to a acceptable height. The handling of the car on the street has not changed with these adjustments.

I got a set of MPSC2 and will take 8 rims. Will try the R 7s, and sell cheap if they rub. My set up is dialed.

Seems like the R7's will be in PIA unless car adjustments are made. My car is lowered and I have a lot of camber. I need to pull the trigger in a few days and if I can get a set of R6's I will probably go that direction than having to worry about making car adjustments.

I'm thinking that when my car is lowered a bit again and a little more track camber added that the 245/35 will work vs. 245/40... From Comp Motor Sport input earlier in this thread many more of the 6t3 folks are running the /35....

Do you know what your ride height is?
