Hi guys, I'm looking for some help on proper (AKA legal) backspace measurements for an ITA 240SX. I plan on buying Diamond Racing 15x7 for my car, but the measurement techniques are tricky enough that I'm not sure Ive got the numbers right (Hard to measure with the suspension loaded, and inacurate measurements with the weight off)
To let you know, all measurements are made considering using Hoosier 225/45
From what I can tell I would be able to barely get by with 4" BS on the front, but would need 3.5" BS on the rear. I don't want to buy 2 different wheels, so that would mean I would have to sacrifice 1" of track on the front and go with the 3.5.
Is anyone out there running Diamonds on their car & what backspace are you using?
Thanks,
Mike
