How does the Dynamic Mount system improve brake performance?

The Dynamic Mount system allows the brake rotor to expand and contract freely with heat cycles, independent of the hat. This reduces stress, keeps the rotor flatter, and eliminates pad knock-back and rotor drag, leading to a more consistent pedal feel and improved response.

What are the stud sizes on this brake rotor hat?

This Wilwood brake rotor hat is designed to accommodate 11/16 inch studs.

What is the bolt circle pattern for this rotor hat?

This rotor hat features an 8 on 7.00 inch bolt circle pattern.

Product Details

This is the Wilwood Dynamic Drag brake rotor hat, part number 170-12431. It's designed to work with specific brake rotor applications, featuring an 8 on 7.00 inch bolt circle and a 1.96 inch offset. This hat is a key component for a brake system where consistent performance under heat is critical.

What makes this hat stand out is its Dynamic Mount system. Unlike traditional hats that bolt directly to the rotor, this design lets the rotor expand and contract independently as it heats up and cools down. This means less stress on the rotor attachment points, helping the rotors stay flatter and run truer. You'll notice improved brake response and a more consistent pedal feel because pad knock-back and rotor drag are eliminated. The hat itself also stays straighter, avoiding distortion from the rotor's thermal cycles.

This setup is particularly beneficial for applications that see significant heat. By managing thermal expansion, it helps prevent issues like bolt hole misalignment when it's time to replace rotors on a used hat, making future maintenance simpler.
