Here's my current setup:
F: 18x9 et42 w/10mm spacer (will go 7.5 - 8mm this spring) 255/35 RE71R @ -3.1*
R: 18x9.5 et43, no spacer, 265/35 RE71R @ -2.2*
KW CS 3-way w/ remote reservoirs, F8X LCA/TS's, Brembo GT 6/4 pot 380/345 (these were the only wheels that allowed for the front clearance.
Fenders rolled/pulled, no rubbing except for big freeway dips and it's only on the front of the fender liner, could be mitigated but haven't bothered since it rarely happens. Planning to fit 9.5" square with 255's next..
