Sprint Brake Kit LF Alum Rotor

The WILWOOD Sprint Brake Kit LF Alum Rotor is a purpose-built left-front brake assembly engineered for high-performance sprint car competition and extreme motorsport environments. This kit combines a 2-piston caliper architecture with an 11-inch drilled aluminum rotor to deliver consistent stopping power under sustained high-heat conditions typical of short-track racing. The gray anodized aluminum construction provides corrosion resistance while minimizing unsprung weight—a critical factor in sprint car dynamics where every pound of rotational mass directly impacts acceleration and handling response.

The 11.000-inch drilled rotor geometry enhances thermal dissipation and cooling airflow throughout braking cycles, essential for maintaining brake system fade resistance during extended racing sessions. The 2-piston caliper design offers a balanced clamping force distribution across the rotor friction surface, reducing pad wear variation and extending component life between service intervals. This assembly is specifically configured for sprint car spindle mounting patterns, ensuring OEM-level fitment compatibility. The kit ships as a complete left-front package, ready for direct installation without requiring additional adapters or fabrication.

Sprint car drivers, short-track race teams, and competitive hot-rod builders rely on WILWOOD brake systems for predictable modulation and repeatable performance lap after lap. The Dynalite product line represents a mature engineering platform proven through thousands of competitive miles across North American dirt and asphalt tracks. This left-front configuration allows teams to build matched brake systems by pairing with corresponding right-front and rear assemblies. Weighing 6.85 pounds, the complete kit represents a lightweight solution that preserves vehicle balance and acceleration characteristics critical to competitive racing success.
