This is a great website!
I have the 330 with SP and looking at rims that are 18x8.5 (37 ET) and 18x9.5 (43 ET), I will be using the OEM tires 225 & 255. After using the calculator (which is awesome BTW) it tells me: 19mm LESS clearance on the strut side, and the outside edge of the wheel will EXTEND an extra 7mm.
I don't know if it will fit right, look right or rub? Would anyone know?
Kudos to the creator of the calculator, you're a genius.
