what rims did the A9X have?, when i met rodney and jennie there panel beater had a 4 door A9X and it had the different offset rims that looks to be the same as this one, with 2 bigger lips, i went and had a look at one of my gts rims and it has a the bigger lower lip and a smaller upper lip if you get what i mean, it is only a 6" tho, where as yours has 2 bigger lips, might be worth investigating, but theres a fair chance ive got not idea what im talking about
