Second time now I have to replace the rear rims on my savage. The car has so much power I keep spinning the hubs in the rims. The guys at hobby shop say its better to keep buying the composit ones. I'm gunna look into the aluminum ones just for the heck of it. Has anyone ever had the same problem? If I loosen the slipper cluth it burns the disk way to hot. And I have the hub nuts real tight, its not because they work loose
