17 x 8

[JeffTepper]

Here's the scoop on the car in the sig pic

Brand and model of wheels- Ultra 454
Front wheel Size and backspace-  17x8 with 4.25 bs
Front tire brand and size-  BFG KDWS 235/45x17
Rear wheel Size and backspace- 17x8 with 4.25 bs
Rear tire brand and size-  BFG KDWS 245/45x17
Front springs-  Eibach progressive coils with 1" poly spacer on Open Tracker Roller Perches
Rear Springs-  Stock
Misc (Provide details of your setup, lowering blocks, Arning drop, etc)- Fender lips rolled but still a tight fit.  Conventional wisdom says 4.75 bs is the way to go on 17x8 rims

Sigh.. Very jealous.. I have the knockoffs coming in the mail.. http://www.rev-wheel.com/oe/340sc.html

8" and 9"... 4.5 and 5 backspacing.. I want to fit 275 on the rear but I'm not sure if it's going to happen.
