get ready to throw away those heavy Volvo calipers.......sure it does not bolt on without an adapter plate, but it also has the regular brake circuit so no funky hose adapter needs to be used to block off the secondary circuit...
yes, I know the rotor is rusted...bradholio had the damn thing sitting in the back of his truck in the snow.....
oh yea..for those not in the know...stock early vented 911 front rotor.....
