SPF rear wheels

[Powershift1038]

Anyone know what the rear wheel width and offset is on our SPF cars? Thanks.

You will get slightly different answers depending on sequence/build #, as SPF changed from Trigos to other makes from time to time. My #747 had Trigos measuring as follows:

FRONTS 7.5" wide w/3.75" backspace/offset
REARS 9.5" wide w/3.75" backspace/offset

Thanks for the info. Do you know how to identify if they are Trigo wheels? I looked mine over (while on the car) and didn't find a name anywhere.

I pick up my rear rims from the "widening shop" tomorrow afternoon. I will take a look at them then (or take a peek at the fronts tonight).

My original 15" rear wheels that came on Superformance 2040 are 3.6" back space and 9.5" wide.

I run an identical looking 4" back space 9.5" wide 15" wheel from Vintage wheels in order to move more rubber inward with wider tires.
