drag wheel set up questions

[bullitt784]

what should the backspacing be for 15s on our machs? are the following correct?


15X10 with 6.5" bs
15X8 with 5.5" bs


i was looking at either, the 15X10 with a 325/50/15 MT ET street radial or the latter with a 275/50/15 MT ET street radial. not sure the first one would fit but want to make sure first and foremost that i'd be getting proper fitting wheels. any help would also be appreciated as well as telling me what you guys have as drag setups. :beer:

btw, i have GT rear brakes

If you run a 15x10 6.5bs you will have to grind the banjo bolt next to the caliper, Has I did for my bogarts, I would also rec a et street over a MT DR's for a stick car, The sidewall is softer on the et street and works better and the DR's are harder on parts from what I done.

The 15x10 w/6.5 BS will be perfect . No grinding of the Banjo bolt will be required .
This tire would be the one to use if you are pushing some good power . You would want a beefed up rear . This tire has the stiffer sidewall . Notice the S at the end of the specs..
