These Stainless Steel Brakes Force 10 3 piston disc brake kits for the 1998-2002 F-Body Camaro and Firebird feature a 3 piston design that applies pressure to both sides of the 13” rotor, resulting in increased braking performance. Their lightweight aluminum construction reduces unsprung weight for better ride quality, and corrosion-free stainless steel pistons minimize heat transfer to the brake fluid for optimum performance.
