Need help with backspacing
I am having a set of 19" wheel blanks made for me, which I will then machine the rest of the wheel myself. I'm going to run an 8" wide wheel front and rear, and I want them to have the same backspacing. I'm currently running ROH ZS wheels that are 8.5" wide with 4.5" of backspacing. I've searched through a lot of posts and it looks like most people running aftermarket 8" wide wheels are using 4.5" backspacing. But, I talked to someone at SLP about the new ZR1 wheels for thirdgens and they run 5.5" of backspacing for an 8" wide wheel. I don't want the wheels to stick out at all, and if they sit in a little more then my current wheels that will be ok because my rear wheels come real close to my fender lip when I let my Air-Ride down. What do you guys suggest for backspacing? Thanks for your help.
