One pair of front 1998/2002 LS1 EradiSpeed rotors are still a direct OEM replacement, but the "plus" indicated rotors that are of a two-piece design. An EradiSpeed+ hat is CNC machined from billet or forged aluminum and anodized black. The hats and rotors are joined by the same hardware used in Indy cars. With a two-piece design, EradiSpeed+ units provide a welcome reduction in total rotor weight.Front Rotors 1998/2002 LS1
One pair of 1998/2002 LS1 Rear Rotors EradiSpeed rotors are direct replacement performance rotors that are cast with an integral hat just like the original OEM rotor. Each one however, is a unique casting which employs either a directional curved vane or the patented Kangaroo™ port design. All EradiSpeed rotors benefit from additional mass in the "firepath", as well as a proprietary, high-friction iron formulation. Rear Rotors 1998/2002 LS1
