Centric Parts has introduced its new line of StopTech GCX Disc Brake Rotors. A division of APC Automotive, the company’s latest offering is engineered to restore OE performance and protect from rust and corrosion. The rotors have a partial Geomet-brand coating on the friction surface. That means a 10 per cent faster pad bed-in while eliminating corrosion rings. The same coating is on all non-mating surfaces to inhibit rust formation and provide corrosion resistance. The line has 475 SKUs and covers 80 per cent of vehicles in operation.
