im running 16x8+27's w/ -1.7 degree camber rear and -2.2 degree camber front... the front is maxed out yet and i can still lower it another 2 inches or so until it has maxed to the spring seat and lock. but the rear on the other hand has maxed. I understand that the closer the wheel is to 0 the more it will stick out and with my experience on 0 offset they will flushen up on the fenders w/o even lowering the vehicle.
for instance i had 15x7+20 and they were sunken in with the same height, i opted for 0 offset and they sat flush w/o any tire gap so maybe when and if i run some 15+mm spacers it will get rid of the gap.. time to make a run to the local tire shop for some bolt on spacers... let you guys know how that work out later.
