I have 7" under stock guards and a ir you look at the Wakefield pics Deiter's car (lime green) has run 8"s
It is all to do with offset.
It is not how wide it is but its relation with the centre.
Supers are a little difficult cause of the wide track at the front.
My ET (offset) is 40mm at the front and 50mm at the rear.
If you want to run steel wheels it is easy cause you just get them made up for this. Mags is a lot harder.
I also run a narrowed spring on the strut tower.
