it's not mine...But the owner says they don't much, only a bit on the lower corner of the front bumper. but he plans to trim it the tire clearance problem on a newer gen (EJ) subaru is not in the fenderwells, but the lower spring perch. these are only 27s, and he's only got about 1/2" of clearance between the tire and spring perch.
if you switch to somesort of coilover there will be a much smaller spring perch. so get some coils and problem solved.
