I received a set of Volk CE28N 18x8.5 +40 front, 18x9.5 +40 for rear per Steve @ Mackin recommendation. The front are fine with 245-40 Pilot Sports the rear rub with 275-35. The offset he recommended is obviously wrong. I have Eibach and Tokico D-Spec setup. Only other offset available in Mercury Silver is +42. Will rolling fender work @ 60% roll or should I go with Titanium Silver color which has a +47 available in 18x9.5. Has anyone done this? Help!
