Wilwood Drilled Aluminum Brake Rotor

Universal Fitment - 3 x 5.00" Bolt Pattern

Part #: 160-3411A

Overview

The Wilwood Drilled Aluminum Brake Rotor is a high-performance braking component designed for sprint and midget race cars and other vehicles utilizing the popular 3 x 5.00" bolt pattern. Crafted from high-strength billet aluminum, this rotor offers a lightweight yet durable solution for drivers seeking improved braking performance and reduced unsprung weight. Whether you are a competitive racer or an enthusiast looking to upgrade your braking system, this rotor delivers precision engineering and reliable stopping power.

Built to exacting standards, the rotor’s drilled and slotted design enhances heat dissipation and helps maintain consistent brake performance under demanding conditions. Its black finish not only adds a sleek, professional appearance but also provides corrosion resistance to extend the rotor’s service life. This rotor is ideal for those who want a balance of performance, durability, and style in their braking components.

Key Features

Wilwood’s drilled aluminum rotor incorporates advanced design and manufacturing techniques to ensure superior performance and reliability. Key features include:

• Precision CNC machining from high-strength billet aluminum plate for exceptional strength and lightweight construction.
• Full symmetrical machining ensures perfect balance and flatness, resulting in the truest rotation and reduced brake judder.
• Engineered drill and relief slot pattern optimizes heat dissipation and helps prevent brake fade during intense use.
• Designed specifically for the 3 x 5.00" bolt pattern, common on sprint and midget front hubs, ensuring direct fitment without modification.
• Black anodized finish provides corrosion resistance and a clean, professional look.
• Rotor thickness of 0.313" and outer diameter of 10.200" deliver a robust braking surface for consistent pedal feel.
• Lightweight aluminum construction reduces unsprung weight, improving suspension response and vehicle handling.

Construction & Design

This rotor is crafted from billet aluminum, a material known for its excellent strength-to-weight ratio and thermal conductivity. The use of billet plate allows Wilwood to CNC machine the rotor with tight tolerances, resulting in a perfectly flat and balanced component. The symmetrical machining process eliminates any warping or runout, which can cause brake pulsation or uneven pad wear.

The drilled holes and relief slots are strategically placed to maximize airflow across the rotor surface, accelerating heat dissipation and reducing the risk of brake fade during repeated heavy braking. This design also helps to evacuate water and debris, maintaining consistent braking performance in various conditions.

The black anodized finish not only enhances corrosion resistance but also adds a sleek aesthetic that complements high-performance brake systems. Overall, the rotor’s construction and design reflect Wilwood’s commitment to quality and performance in motorsports applications.

Installation & Fitment

The Wilwood Drilled Aluminum Brake Rotor is designed for direct bolt-on installation to hubs with a 3 x 5.00" bolt pattern, commonly found on sprint and midget race cars. It uses existing mounting points and requires no modifications, cutting, or special tuning to fit properly. This ensures a straightforward upgrade process for racers and enthusiasts alike.
