What is the main benefit of the drilled and slotted design?

The drilled holes and slots help vent gases and heat away from the brake pad and rotor surface. This action reduces pad glazing, disperses heat, and prevents uneven pad material buildup, leading to improved and more consistent braking performance.

Does this rotor come with mounting hardware?

This product listing is for the brake rotor only. Mounting hardware, such as lug nuts or rotor bolts, is typically sold separately and should be confirmed with the manufacturer's specifications.

What does 'directional' mean for the drilling pattern?

A directional drilling pattern means the holes are oriented to work with the rotor's rotation in a specific direction. This ensures optimal airflow and gas expulsion for improved cooling and performance when installed correctly on the correct side of the vehicle.

Product Details

When you're pushing your vehicle hard, especially during spirited driving or track days, you need brake rotors that can keep up. These Wilwood SRP Drilled Performance Rotors are built to handle the heat and stress that come with demanding braking situations. They feature a directional cross-drill and face slot pattern designed to work together to improve how your brakes respond and how your pads perform, whether you're doing light stopping or heavy braking.

The holes and slots on these rotors do more than just look good; they actively help your braking system. They help clear away gases and heat that build up between the pad and rotor, which can cause pad glazing and reduce stopping power. This venting action also helps prevent uneven pad material from building up on the rotor surface, leading to smoother braking and a more consistent pedal feel. Plus, the material removed for the drilling and slotting actually helps reduce the rotating and unsprung weight of your suspension, which can have a positive effect on overall vehicle dynamics.

This specific rotor measures 12.88 inches in diameter with a 1.00-inch thickness and features a 12-bolt mounting pattern on an 8.75-inch diameter hat. The black finish adds a clean look behind your wheels.
