Wilwood HD48 SPC37 LH 11.75 x 1.21 8 on 7.00 160-13498

When you're pushing your vehicle to the limit—whether on the track or the street—brake performance is non-negotiable. The Wilwood HD48 SPC37 LH rotor delivers the thermal management and stopping power you need through its directional vane design and Spec-37 iron construction, engineered to withstand extreme temperatures without distortion or cracking. Built for driver's side applications with a proven 8 x 7.00-inch bolt pattern, this rotor integrates seamlessly into high-performance brake systems that demand reliability under sustained hard braking.

The 48 curved vanes work in concert with the directional design to channel heat away from the braking surface, maintaining consistent friction and pad contact lap after lap. The plain face finish eliminates complications during installation and promotes even pad wear, while Spec-37 iron's exceptional durability resists the warping and thermal fatigue common in lesser materials. Whether you're running a dedicated race car or a street machine with serious stopping requirements, this rotor proves itself in demanding applications.
