backspacing and offset

MonteC · 03-23-2011, 07:20 PM

Any one here know how to calculate all of this out? Im needing new wheels to clear the front tubular suspension and the c5 brake calipers/rotors.

Im not sure what b/s and offset im going to be needing. Any help?

cardboard. lol

backspacing is the measured distance from the back of the rim to the matting surface. offset is the measured distance away from the (imaginary) line down the center of the wheel.

usually you would use one or the other to look for rims.

The back is 4.5 with stock frame rail. Notch frame 6" bs will fit.10" width is the widest I would go. I don't know about the front.

The front is my main issue.

Summit sells a neat little tool that bolts to your hub and is adjustable to different bs and wheel diameters.
