Title: offset and backspacing on a c10
Post by: the dan on May 19, 2008, 12:54:38 am

so im in on the buy of some 20" rims, preferably one of these

(http://static.summitracing.com/global/images/prod/large/ale-875-78512_cp.jpg)

Rim Width (in): 9.00 in.
Backspacing (in): 4.750 in.
Offset (mm): -6.00mm



or

Rim Width (in): 8.50 in.
Backspacing (in): 5.671 in.
Offset (mm): +25.00mm

so will both work? im 5/6 dropped and am sure i need the right backspacing to tuck rims, any0one know what i may expect for spaces on either or both?

They should work, most people run 5"-5.5" BS. What size tire are you running? And It is best to look and do all the numbers your self be fore buying wheels..
