Wilwood GT 48 Slotted Curved Vane Spec-37 Dynamic 12 Lug Mount Rotor 13in Dia. 1.25in Width - L/H

If you're building a high-performance braking system for track days or serious street use, a rotor like this Wilwood GT 48 is a critical component. This is a left-hand side rotor, designed to work with specific caliper and hub assemblies to ensure proper rotation and heat dissipation. It measures 13 inches in diameter and has a 1.25-inch width, providing a substantial surface area for your brake pads to grip.

This rotor is constructed from Wilwood's Spec-37 iron alloy, which is known for its ability to withstand high temperatures without warping or cracking. The GT 48 design features curved vanes inside the rotor, which help to pull air through the rotor as it spins, actively cooling the braking surface. This is crucial for maintaining consistent stopping power during repeated hard braking events. The slots on the rotor face are not just for looks; they help to clear away brake dust and gases that can build up between the pad and rotor, ensuring a cleaner, more consistent friction surface. The 12 lug mount pattern offers a secure and robust connection to your brake hat.

When installing a rotor like this, it's important to ensure it's paired with the correct caliper and hub assembly for your application. Always refer to the manufacturer's installation instructions for proper torque specifications and any specific hardware requirements. This rotor is designed to be a direct replacement for specific Wilwood brake kits, so confirm your kit's compatibility before ordering.
