I had mine rolled after going to 18x8 fronts and 18x9 rears with Michelin Pilot Super Sports at 235/40/18 and 255/35/18, respectively. I was getting rub when the suspension was compressed through bumps at higher speeds. This resolved the front rub, but the rears still rubbed on the little winglets at the rear of the fenders. I switch back to the stock wheels for track days to be sure there won't be any issues with rub and excess damage to my car. Disappointing since the whole point of getting forged rims were to reduce weight and step up to wider rubber. I believe some folks have run up to 245 front and 265 rears without problems, so your offset and results may vary!
