914World.com _ 914World Garage _ Maximum rear wheel backspacing?

Posted by: Eddie914 Oct 26 2004, 12:42 PM

At what backspacing do the rear tires/wheels contact the rear inner fenders?

Assume:

-2 degrees camber.
245/45/16 tire
16 x 9 wheel

Thanks

Eddie

My 15x8 with a 9.5 in slick would hit with a backspace of 5 inches. Ran about the same settings as far as suspension goes. Put a .250 spacer and problem solved.

a 16*8 rim with a 55mm offset and with 225 width tire hit both the trailing arm and the trunk wall....backspacing wise, if you included the thickness of the rim lip, you'd have a rim with about a 6.5" backspace which is too much.
