761 MPH

Anyone running 20" wheels, and know the backspacing #'s for the right look and fit?

I am looking at 20X8 American Racing TT2's in front and 20X10's in back.

Can 20X10's fit all 4 corners, or would staggered be the way to go?

Also, any tire size/brand suggestions would be appreciated.

The Saleen looks great in it's 20's, and I wonder what those specs are.
(I will be dropping mine 1.5-2" or so.)

Thanks!

The x10's will fit on all corners, but I cannot find the offset/backspacing info. Roush is using 18x10 all around on the new ones, but won't tell me their sizing info

Thanks Aaron, maybe I'll bug them about it. I think the "offset" is +45mm from what I have read in this forum, but I need to decipher how that all translates into ordering rims that fit correctly.

761,

the offsets for 20s are typically 35mm'ish F and 40mm'ish out back. these will accomodate 255 tires front, and 285s in the rear. that is the popular widths guys are running i believe. a 265F or 275R is not out of the question. that is with the above offsets.

off hand, i know of only two wheels that have more aggressive offsets in 20" dia. they are my Axis GT-Rs and Weld Forgestar 750 or 850s.

Axis offsets are: +37mm front and +46mm rear. widths are 9"F & 10.5" R.

Welds are: 50mm front and 55mm rear i believe. you can see the welds at tirerack.com they are under the label, "Evo" widths are 9.5"F & 11"R.

i am running 275/30-20s F and 305/25-20s R. i could stand a little more offset but beggars can't be choosey, huh?

hey Harrier, what springs do you have and how is the ride???

Thanks Harrier,

Actually, those GT-R rims look really good. I may go that route, since the measurements are all pre-determined. (I assume you just bought 'em and bolted 'em ?)
