Very useful little tool.

According to the calculator:

An 8 inch rim with 32 mm offset reduces the inner clearance by 5 mm and extends the outside edge of the wheel an extra 21 mm.

An 8 inch rim with 25 mm offset gives 2 mm of extra clearance on the inside and extends the outer edge of the wheel an extra 28 mm.

I haven't looked at the car and measured; but it seems to me that the 25 mm offset on 8 inch rims might well be problematic. A 28 mm extension of the outer edge of the wheel is a lot.

The 32 mm offset seems more likely to work but I really, really, really don't want any fouling of the arch.

Is anyone running 8 x 17 ET 32 rims having issues with fouling; either inside or on the arch?

with the standard rims, how much clearance is there on the inside, and how much room do you have to play with on the outside?
