Back spacing is 5.5 for 15x8 rear, tire combo will be 275/60/R15.

I'm running these 15x10 6.5" back spacing. Plenty of room to clear my quad shocks and Magnaflow exhaust.

Did you have to switch to different lug nuts/studs to put these wheels on?

You have to run a shank style lug nut (I think thats what its called), your stock lug nuts won't work. I'm running Moser 31 spline axles in the rear wich have a little longer stud, and I have extended front studs as well from Moroso. Do a search on here to see if the stock studs will work. I think NHRA rules state the stud has to stick out 3/8" from the wheel? Someone else can confirm that for me.

This is the best move yet for your car. The 20s weren't cuttin it.

Much better over these...
