Please, Info. on American Racing Chrome Razor 18x9. What are the specs. that will fit on 07 GT? Do you need centering rings? Any issues? Looking to upgrade from stock bullitts.

 

dont see why there would be any issues, should just fit fine.

 

They should be fine. More critical (but probably not an issue) is the offset. Most of the stock wheels on S197's have offset of 45-48 mm. Quite a few aftermarket wheels have offsets in the 30's and people don't seem to have a problem providing they don't put an excessively wide tire on. But with those 9" rims you won't be going there.

Be sure to remove any of the leftover-from-the-assembly line and no longer needed metal clips on any of the wheel studs. They'll cause some aftermarket wheels to not sit flush against the rotor and can cause vibration and wheel shake.
