17x9 Torq Thrust M on s197 spacers ???

I just ordered some 17x9 Shelby Torq Thrust M wheels and I am going with 255/45-17's for tire size. I'm aware it is a one inch smaller diameter than the factory size. What I need to know, is anyone running the 17x9 Torq Thrust M wheels on a S197 Mustang ? Tire rack includes 2 wheel spacers with the wheels I just found out. I called American Racing and they say there's no reason why you would need them. I'm not sure I believe them because this same guy told me that the 17x9 had a 2 1/2 - 3 inch lip on the wheel. Tire Rack's spec says it has a one inch lip... The last thing I want to have to do is put wheel spacers on brand new wheels.. Any information would be appreciated..

As a side note, presently my car has 18x9 American Muscle Deep Dish bullets and with the BFG KDW2's mounted on them they weigh 55.6 lbs each... ouch... The 17x9 Torq Thrust M's with the tires I'm getting weigh 45 lbs. A 10 lbs per wheel/tire combination saving is huge and it could only help the performance of my car..



Thanks,

Mark

Thanks Cosmo. What size tires are you running ? So you're not using the spacers ?
