Running 15x7 ET37 with 205-50-15 on the track. If I turn the wheels to max right or left, it hits the inside fender (don't know what's is called), not the plastic but the metal behind the spring. With 195-50-15 there is no problem at all. With both tires there are no problem with the outer fenders, front or back, if you have a adjustable panhard rod.
