15x7 FW rally wheels backspacing

Quick question about rallies.
Do all 15x7 FW rally wheels have the same backspacing?
Thanks,
Chuck

Quick answer = No...
You'll need the rim code and manufacturer to know for sure.
Many are close to 4.25~4.5" though...

Code is K15 20FW. Does that help?

Re: 15x7 FW rally wheels backspacing

It does - but, you may want to recheck numbers - there seems to be a digit (or so) missing from one side or the other of the valve stem.

The "FW" is a 'JJ' rim profile 15X7" rim with a .30"* offset.
GM #3997899 (Group 5.803) with applications from 1969 ~ 1975.
Listed as a service replacement for part #3970531 wheel for 1969 Camaros w/Disc Brakes Front and Rear (RPO-JL8) and w/ 302 option (RPO-Z28).
Listed as a standard or replacement wheel for 1970~75 Monte Carlo and 1974~75 Chevelle (exc. wagon).
Welded construction, 4 cap projections and Tubeless rated.

Code you gave may be missing a number or two - but, looks like a Kelsey Hayes Rally from the Romulus, MI plant manufactured in ? (1975?) on ???

*Some conflict in GM documents about this - measure the 'backspace' and see if it isn't slightly more than 4 1/2".

Hope some of this helps;
John

Re: 15x7 FW rally wheels backspacing

Yes, they will all have 4.25 inch backspacing. "FW" is a 15 x 7 rally wheel used on Monte Carlos in the early 70's,..and will work great on your first gen.

Thumbs up Re: 15x7 FW rally wheels backspacing

I bought 6 FW all sandblasted and painted for $45.00 each. Saves a lot of extra money ,instead of buying certain coded wheels,and not knowing if they are bent or not.
Put them on a 68 SS matching 4 speed with drum brake all around.
