Offset is a big part of how RWB sticks the wheels out so far. Looks like spacers are also used. Here are some of our promo pictures from RWB Thailand:

wheel off-set and spacer, depend on the look you going after or the wheel off-set.
my car base on 964 turbo and have 15mm spacer in the rear.

By moving the rear fender oil lines down and shaving the wheel alignment bolts flush with the nuts I was able to fit a set of ultra wide custom 17" Fuchs under OE 930 rear flairs. You have 13.5" of total space available, these wheels measure 13.25" outer bead to outer bead. Using 315/35 tires allowed the sidewalls to just barely extend beyond the bead. It is as tight as I could go and not have any rubbing under any circumstances.

Besides a race car where you expect to replace items from racing. I've always heard that much offset is hard on the wheel bearings. I like the look much better than the current trend with the offset going the other way. However anyone have any experience regarding the load on the wheel bearings?

Thank you great info, Kevin
