My pic above has the correct 17" multi spokes for the 330's. If the Multispokes on the 2003 GTA you are looking at are not the upgrade type like the ones on mine, they will not fit.I am trying to find out if my GTA a 2003 has the correct multispokes that will allow the bigger brakes to be fitted.
If someone could take a pict of the inside of the wheel I could compare it with mine.
Thanks
Paul
