lowering i ordered tt m's from tomz wheels the set up is '''315/35zr17, 17*10.5'' in the back and ''275/40zr17 17*9 in the front'', will i be able to lower it this is going on a 1999 pontiac formula ''offset for the front is +45mm with a 6.75 inch backspace'' ''offset for the back is +44mm with a 7.5 inch backspace''
Well I have TTII's from Tomz but I don't know the actual offset. My car is lowered 1.25" and I had no problems at all, no cutting, bending, or pounding. I just lift the car from the differential. Plus your wheels are 10.5" to my 11".

You should have no problem at all. My car is riding on a set of Sam Strano's springs (~1.2" drop) and I have a set of 315/35/17 Hoosiers for the back, on a set of 17 x 11's with an incorrect off-set for an F-body!! 
I have to run spacers behind them, but with just a little bit of "massaging" of the inner fender wells, they fit fine, and don't rub under normal driving 
.
HOWEVER, those Hoosiers I have are a set of R6's for the race track, and pushing the car hard around corners, there was still a tiny bit of rubbing on the inner fender wells AND the outer fender lip!!
So I rolled the fender lips, and did just a little more work with the BFH (big _ hammer). Very little rubbing going on at all now, and this is on the RACE TRACK, not the street .
Your car should be absolutely FINE on the street
