Description
When you’re pushing your vehicle to its limits on the track, brake reliability becomes non-negotiable. The Wilwood Spec-37 rotor delivers the heat dissipation and pad engagement you need for consistent stopping power through multiple heat cycles, whether you’re racing dirt or asphalt. Built from Wilwood’s proprietary Spec-37 iron alloy, this left-hand rotor resists warping and cracking under extreme temperatures, keeping your braking performance predictable lap after lap.
The slotted design isn’t just for show—it actively improves cooling efficiency and enhances pad bite, which translates to shorter stopping distances and better modulation when it matters most. As a direct bolt-on replacement for older Wilwood models (160-13980 and 160-13981), this rotor integrates seamlessly into existing setups without requiring fabrication or adapter work.
