What makes the Spec-37 iron alloy special?

The Spec-37 iron alloy is a proprietary formulation developed by Wilwood to withstand extreme temperatures. It's designed to resist distortion, warping, cracking, and wear, drawing from technology used in military-spec rotors.

What is the benefit of the curved vane design?

The curved vane design in these rotors provides the highest cooling capacity. This helps manage heat effectively, leading to longer service life and consistent braking performance, especially under demanding conditions.

Does this rotor come with mounting hardware?

This product is for the brake rotor only. Mounting hardware and other brake components like calipers and pads are sold separately.

Product Details

Wilwood is known for making serious braking components for demanding applications. This GT60 curved vane rotor is built using their proprietary Spec-37 iron alloy, which is specifically formulated to handle extreme heat without distorting, warping, cracking, or wearing out prematurely. This alloy is a direct descendant of the materials Wilwood uses for military-spec rotors, so you know it's built tough.

The GT60 rotor features a curved vane design, which is Wilwood's most effective design for maximizing airflow and cooling capacity. This means you get consistent braking performance and a longer service life, especially during intense track use or road course racing. The asymmetrical face slot pattern helps clear dust and gas, and each rotor is dynamically balanced to ensure a smooth, vibration-free experience at any speed. The black e-coat finish adds an extra layer of corrosion resistance, making it a solid choice for applications where appearance and longevity are important.

This rotor measures 16.00 inches in diameter and is 1.38 inches thick, with a bolt circle pattern of 12 on 10.75 inches. It's designed for high-performance braking where heat management and durability are critical.
