Hey, Sorry to bring this back from the dead...
My wings (fenders) have been had the lips grinded away, mainly the rears... I have most of the lip still there on the fronts.. The cars getting a vented wing (like walters) so will get pics and post them up of how much have had to cut off.. As said above, its alll in the offset of the wheels, im running a stupidly high offset which allows me to run the car silly low on big-ish wheels
I'm fitting 195/40's on the front, so can go lower, but I'll save that for shows.. im low enough for everyday use as it is.
cheers..
Replying to your PM's now...
