The wheels are momo GT2's 17x8. I am not sure on the offset but probably factory which should be 30. They fit perfect under the guards with no rubbing.
I've got a set of Panasport G7's 17x9 which I also had 255/40's on and they just fit under the guards. The fronts had a different offset to the rears and were not interchangeable.
Hey I need two new outers for them, one front and one rear. Would you have a contact to the place your getting yours done? We can't get them down here at all.
