i've been running an EST BBK for a couple of months now. the volans required a 15 0r 18mm spacer and peg reps require only a 5mm. that is all well and good but i still have issues with the tire hitting the fender and bending it a tiny bit as well as chewing up the plastic and the edge of the tires themselves. the tires are 215/45 17. i noticed that IPD claims no spacer needed with their kit (and their pegs) and so i wondered what the differences were in the mounting brackets or the rotors that allowed this? anyone out there who has seen both? i'm lowered as well which compounds the problem a bit. any way to run this without funking up my fenders and wells?
