The Wilwood GT-48 Spec-37 curved vane rotor is a high-capacity racing rotor built to withstand extreme temperatures and heavy use. Made from a proprietary iron alloy, it resists distortion, warping, cracking, and wear. An asymmetrical face slot pattern plus individual dynamic balancing help ensure smooth, vibration-free operation while the directional vane design improves cooling and extends service life under track and road-course conditions.
