What is the benefit of a 2-piece rotor design?

A 2-piece rotor design separates the rotor ring from the hat. This allows for better heat management, as the hat can be made from lighter materials and is less exposed to direct heat. It also makes replacing just the rotor ring easier if it wears out.

What does the 48-vane count mean for this rotor?

The 48-vane count refers to the internal vanes within the rotor. More vanes generally mean improved airflow through the rotor, which helps to dissipate heat more effectively during braking. This is important for maintaining consistent stopping power under heavy use.

Does this rotor come with a hat?

Yes, this is a 2-piece rotor assembly, which includes both the rotor ring and the hat. The specific hat configuration is part of the GT48 SPC-37 designation.

Product Details

This Wilwood GT48 rotor features a 48-vane internal vane design, which helps to move air more effectively through the rotor. This improved airflow is crucial for dissipating heat generated during braking, especially under demanding conditions. The rotor measures 11.75 inches in diameter and is 1.25 inches thick, with a bolt circle of 8 on 7.05 inches, making it suitable for specific performance brake system applications.

The GT48 rotor is a 2-piece design, meaning the rotor ring separates from the hat. This construction allows for better thermal management, as the hat can be made from a lighter material and is less exposed to direct heat from the braking surface. This design also simplifies replacement of the rotor ring if it wears out, without needing to replace the entire assembly. The specific SPC-37 designation indicates a particular configuration and material choice by Wilwood for this rotor.

When building a performance brake system, choosing rotors that can handle the heat is essential for consistent stopping power. This Wilwood rotor is a well-built component designed for those who need reliable performance from their braking system.
