Wheel back spacing Q:

I'm trying to buy the Billet Specialties in a 17x9.5 or the 17x11 rear.

Im seeing different back spacing from 3 1/2" all the way up to 7 1/2". The rear end is stock width and I plan on keeping it that way. From what Ive read, the 7 1/2" is the right one, but according to the width of the rim, it varies. Does anyone know the back spacing I would need for the 9.5" and the 11" ?

Thanks

Assuming you're referring to a '93-'02 F-body, I'll toss this out...I have 17x9.5" rims all the way around, with a 7 1/8" backspacing.

For a 17 x 11 you want a 7.75"-8" BS, or +45 to +50 offset.
