D60 15\" rims... 2.75 or 4.5 backspacing? I just got some rims for my D60. They are basic 15x10 black mods from 4WPW that I picked up for $42 a wheel. They came in 2 BS depths, 2.75 and 4.5. I was concerned about how much I might have to grind and the tires rubbing the frame (42x15x15 TSLs) so I got the 2.75 one. But, I test mounted one this weekend to see how much I would have to grind and it didn't hit the caliper at all. With only about 6" of lift and inner fenderwell trimmed to the tub and the axle moved forward 1.5", am I going to have problems with the tire cramming the tub? Should I have gone with the 4.5" BS wheel? What backspacing do you guys run on your 15x10 wheels on a D60?
