Wilwood's GT-48 Spec-37 curved vane rotor is a competition-grade rotor built to handle extreme temperatures and heavy braking. Manufactured from a proprietary iron alloy, it resists distortion, warping, cracking and wear. An asymmetrical face slot pattern and individual dynamic balancing help deliver smooth, vibration-free braking while the rotor's vane geometry increases cooling capacity and service life in track environments.
