What is the purpose of the two-piece rotor design?

A two-piece rotor design separates the braking surface from the hat. This allows for better heat dissipation and reduces the risk of rotor warping under heavy use, as the hat can expand and contract more freely than a solid rotor.

What does the 'SPC-37-RH' designation mean?

SPC-37-RH refers to Wilwood's specific internal vane design for this rotor. This design is optimized for airflow, helping to draw cool air through the rotor and expel hot air, which improves cooling efficiency.

Does this rotor come with mounting hardware?

This listing is for the rotor only. Mounting hardware, such as caliper bolts or bracket hardware, is typically sold separately and should be confirmed based on your specific Wilwood brake kit.

Product Details

Starting with a 12.88-inch diameter and a 1.10-inch thickness, this Wilwood GT48 rotor is built for serious braking performance. The two-piece design, featuring a black electro-coated hat, helps manage heat more effectively than a traditional single-piece rotor. This is important because excessive heat can cause brake fade, reducing your stopping power when you need it most.

The rotor's face has a specific vane design, the SPC-37-RH, which is engineered to help move air through the rotor, further aiding in cooling. This updated vane structure, combined with the two-piece construction, makes it a solid option for vehicles that see frequent hard braking or track use. The black electro-coated hat not only looks sharp but also offers corrosion resistance, keeping your braking system looking good and functioning well.

When you're looking to upgrade your braking system, especially for performance applications, rotors like these are a key component. They are designed to work with specific Wilwood brake kits, so make sure this rotor is compatible with your caliper and bracket setup.
