I have a sneaky suspicion that you have aftermarket mags on and they are not seating properly. With such low mileage the bushes should still be good. The brake discs too should still be good, however they could have gotten warped with heavy breaking and heat build up and rapid cooling ( possibly from going through water seeing as we had so much rain as of late ), but I still have that feeling that there is a mag wheel issue or rim seating issue.
Peter will definitively be able to give you solid advice and input.
