Wilwood Rotor-HD48-LW SPC-37-RH 11.75 x 1.21 - 8 on 7.00in

This is a Wilwood HD 48 Curved Vane brake rotor, measuring 11.75 inches in diameter and 1.21 inches thick. It's built using Wilwood's proprietary Spec-37 iron alloy, which is specifically formulated to handle very high temperatures. This material is known for its strong resistance to distortion, warping, cracking, and wear, drawing on technology used in military-spec rotors.

The rotor features 48 curved vanes designed to help move air and dissipate heat effectively, which is crucial for maintaining consistent braking performance under demanding conditions. The pad contact faces are machined smooth, meaning no slots or cross-drilling, which can be beneficial for certain brake pad materials and applications where a full, consistent contact surface is desired.
