What is the benefit of a 2-piece rotor compared to a 1-piece rotor?

A 2-piece rotor design allows the hat and the friction ring to expand and contract somewhat independently. This helps manage heat more effectively and can reduce the risk of rotor warping or cracking under heavy use.

What does the black electro-coat finish do?

The black electro-coat finish is applied to the non-friction surfaces of the rotor. It provides a layer of protection against rust and corrosion, helping to maintain the rotor's appearance over time.

Does this rotor come with mounting hardware?

This product listing is for the Wilwood GT48 2-piece brake rotor only. Mounting hardware and other brake components, such as calipers and pads, are typically sold separately and must be compatible with this rotor.

Product Details

If you're upgrading your braking system for more demanding use, a high-performance rotor like this Wilwood GT48 is a solid choice. This is a 2-piece rotor, meaning the hat and the friction ring are separate components. This design helps manage heat better than a traditional 1-piece rotor, which is crucial when you're pushing your brakes hard.

This particular rotor measures 12.88 inches in diameter and is 1.25 inches thick, designed to work with specific Wilwood brake kits. The friction ring is made from a strong iron alloy, and it's finished with a black electro-coat. This coating not only looks good but also helps prevent rust and corrosion on the non-friction surfaces, keeping your setup looking sharp even after exposure to the elements. The 2-piece construction also allows for some thermal expansion without causing stress cracks, contributing to its durability.

When installing a 2-piece rotor, it's important to ensure it's compatible with your specific brake caliper and bracket setup. Always refer to the manufacturer's installation guide for proper mounting procedures and torque specifications to get the most out of this well-built component.
