I don't know if these rims gonna fit my 03G Coupe. 19x9, +30mm offset fronts and 19x10, +40mm offset rears. It it gonna scrub my fender if I do a tight turn. Please let me know if I need space(how many mm Front + Rear) or Camber kit.

Trung, that doesn't sound like a good offset for our coupes. I'd stick with
anything in the 20 range....23 or 24 is normal. Call F1 Motorsports and ask
the experts what's the best offset for the G35 Coupe 1-818-755-9800.
There open after 9AM and they know their wheels....

Thanks Gary

mid 20s and lower is where you want the offsets to be
