Hi
I've just noticed your thread and thought i'd post some input for you!
You've probably seen my car around and about on the forum, i've got 9 X 16 Brock B" rims with an ET15 offset.
If I can get no scrubbing on the rear of my car then i'm sure you can. I opted for G60 arches as my rims are that much wider and the offset makes the rims stick out waaaaay to much.
Get a body shop to panel beat the rears out, not cut away, just beat them out, then get G60's riveted and bonded onto the car. Thats how mine was done and I have practically no scubbing at all. FK's will make the car stiffer and allow me to drop lower and still have no scrubbing.
hope that helps!!
