Any advise on front hubs for an NA? I have detected a whine at about 70 mph and believe it could be front bearings as they have never been replaced. I have priced several on the net and the local auto parts store will supply them as well. I am interested in quality as this car only gets track/AX/TT beatings. Is there a brand that is lighter than stock? Is a low milage used part an viable option?
