I'm talking typical sports car driving turns at 45 - 60+ mph that creates substantial front down force.
You may also experience some rub when you are turning in reverse and crank the wheel hard to the left or right.
I am running the Conti's as well. After a few dozen rubs, you'll see three little patches under your wheel well where the tire is making contact. It is on the inboard side of the tire, aligned with the inboard edge of the tread on your tire.
After quite a few days at the track and some seriously fast canton driving, I have worn down three (now highly polished) spots, all the way down to the bare aluminum. I'm afraid that if I don't increase the space by appx. 1/4" I will eventually wear right through the aluminum and shred my tire... Not good if you're doing 75mph turns with 10 other sports cars only inches away from you on a race track...
I'm looking at the possibility of stiffening the front tortion bar to limit the body roll on those hard turns, but I'm not sure that will achieve the FIX. And I'm afraid that when I go to a bit beefier RACE tire, the problem will get worse.
Although the spots under the wheel well look like they could be heated and pounded in / up to give a bit more clearance, since they are very small (about 2"w x 4"l)
I'll keep you posted...
After reading this post and reading your post under the RACING category it reminded me of my first Corvette that I bought new in 1978. Back then, the standard tire was a Goodyear 70 series radial. The optional performance tire was a 60 series Goodyear Eagle GT, raised white letters, etc. The GM wisdom at the time, in order to resolve a tire rubbing problem on the inside lip of the front fenders, during hard turn, was as follows: they actually "shaved" about 1/2" off the inside lip (fibreglass), almost the entire fender well, to allow enough clearance for the tire. This was done at the factory and only for the cars with performance tire option. If you ever see a 1978 Corvette, check the inside front lips and you will know what tire option the car came with.
Amazing but true!
