Wilwood Super Alloy Titanium Slotted Rotors are Sprint racing's lightest rotors at a weight of between 2.8 to 3 pounds with a directional slotted surface allowing for full pad contact. This provides excellent high temperature stability, with rapid heat dissipation and consistent performance from the brake pads. Super Alloy Titanium Slotted Rotors are Sprint racing's lightest rotors at a weight of between 2.8 to 3 pounds. Wilwood's proprietary Super Alloy Titanium greatly enhances the durability and lifespan of this rotor over comparable lightweight steel or iron rotors. A directional slotted surface allowing for full pad contact. This provides excellent high temperature stability, with rapid heat dissipation and consistent performance from the brake pads. The fine micro-finish surface beds quickly with new pads. It provides a cost effective, lightweight solution with quick response, long service life from the pads, and consistent braking at all temperatures. Lowered rotating weight promotes quick acceleration, deceleration, and improved handling.
