'05 gt bullitts

According to the laster MM&FF, the 17" wheels will fit only if you are running an SN95 brake setup using the SN95 offset in the rear.

You still need to change the tires though. The 235/55's are too tall. You need 245/45's.

In the pictures, it looked like a good stance. I like it with the newer bullitts...thinking of trying it myself.

The 18's won't work. Rim hits the strut
 
yeah i was bumed about this too, the whole reson i wanted to get the take off's is the p-zero's and the bullit. but if you can only use the wheel's what's the point, they look the same as the bullit's that are made for a car almost identical to ours, to much work, to little gain imho
