You won't have enough clearance to use camber bolts in the front. You'll have the same amount of clearance on aftermarket springs as you do on OEM springs, because you're looking at clearance from the spring perch, not the spring itself. There are pics in the first post of
this thread showing how much clearance there is to the spring perch.
If you want to run a spacer on the front, don't go larger than 3mm without replacing the OEM lugs with longer ones.
