Here is my setup.
19" F Sport Forged Accessory Rims
: 19x8 +30 offset (45 offset - 15mm Ichiba V2 Hubcentric Spacers)
225/35/19 Michelin Pilot Super Sport
: 19x9 +40 offset
255/30/19 Michelin Pilot Super Sport
Camber before dropping on RS*R Down Springs (extra info if you want). Obviously these values have changed as I am lowered now...
FL: -0.8 camber
FR: -0.8 camber
RL: -1.8 camber
RR: -1.9 camber
The rear setup right now has about 1.5 cm clearance from the fender liner/ fender. I guess it's prob at the limit if you don't want to rub. I carried 3 passengers and it did not rub in any way but if you load up the trunk, I'm sure it'd rub.
