Buckled and cracked. Spoke to some people about it, but apparently it's very hard to fix. They'll probably have to put the centre into a new rim. So they can go in the shed for a while I guess. The new rims seem to be a multi stud. I'm hoping they will also fit a 5x100 pcd so I can keep them when I sell the car and not have wasted my money.
The new rims are ANZ brand.
