I run 255/35R18 tires in the front, which limits space tremendously for flexible pipe to fit without getting pinched. This week-end, I will jack the car up, sit the tires on four blocks of wood to get normal suspension compression, and slide under the car for a closer observation. Will also turn the streering wheel from lock-to-lock.
255/35r18 tires in the front? Do you use any spacers, is your car lowered?
My car is slightly lowered and i am running negative 3.8 camber up front with 3mm spacers, front fenders rolled and flared, i still cant fit anything bigger than 245/35 without rubbing everywere. But i am using r-compound tires that run wider in the same size. Might try street tires now, getting tired swapping them at the track every time.
