T.O.P. Racing 5.3mm aluminium ball studs
T.O.P. Racing have developed new high precision 5.3mm 7075-T6 aluminium ball studs for the company’s on-road line of vehicles such as the Photon, Sabre and the mini touring car series. The red anodised alloy ball studs are light yet strong and come as 5mm and 8mm long variant to replace the original steel ball studs while the inner hex allows for swift and easy wrenching.
