Torque Thrust II Question

[fillpot]

Guy's bought a set of chrome 17x11 with 6in backspacing torque thrust off of ebay for a real good deal,but the backspacing is a little closer than i thought it would be,basically the outside of the wheel is just about flush with the inside of the quarter panel,my lips have been rolled but I can see some rubbing issues fixing to happen even though I don't have the tires mounted which i havent ordered yet because i wanted to run 335's and there kind of pricey.Ok here's the question i noticed that the hub on these are pretty thick and was wondeeing if i might could machine off a little bit on the inside of the wheel,maybe a 1/8 or so,it would still be close but I think it would work,has anyone done this and if so who did it for ya,there's a local machine shop here in town that might could do it but they may also scratch the hell out of the wheels.BTW the car is a 69 camaro,mini tubed,G-linked,9in,and just some basic disc brakes.Just wanted to run it by yall before i put the wheels back up for sale.Also if i get this worked out what backspacing do i need for the front with either a 17x7 or 17x8 with disc brakes.I probably should have included the width of the rear end but for some dam reason i cant remember it but will check it tomorrow.Thanks everybody!
