So at bedford my last track day the rear disks held up well. All brakes were on point. But the rear disks got so hot the peeled the paint off the disks and now they look shit with rust patches. I need to change the rear disks due to a dodgey wheel bolt thread. I looked at MTEC disks and they looked good. Im not kean on grooved or drilled disks but im thinking it might be good on the rear. I know the standard ones are good enough for track but im not looking for extra bite just better made ones. Any recommendations or thoughts? Off to spa in april so need to be replaced before then.
