That's a real pity as 295 rubber on the back would look amazing! It looks like what I have on the car now is 18" rims, 10" wide and with an offset of 47 also. That means that the new rims would only intrude 7mm on the inside, which might be alright, but 33mm on the outside which would likely cause issues with the wheel arch, if I've used the
Wheel Offset Calculator correctly.
I did do a search before posting, but couldn't locate a definitive response. Thanks again for your input.
