Wilwood 120-17212-RD XRS6R Six-Piston Radial Mount Brake Caliper Left Hand Red

The Wilwood 120-17212-RD is an XRS6R (Xtreme Race Six-Piston Radial Mount) brake caliper in a left-hand orientation, finished in Wilwood's signature red powdercoat. Engineered for high-performance racing and track applications, the XRS6R series delivers exceptional clamping force and thermal management for demanding braking conditions.

Key Features:

• Six-piston design — staggered piston sizing provides even pad wear and balanced clamping force across the rotor face
• Radial mount configuration — ensures rigid, precise caliper positioning for consistent brake feel and reduced flex under load
• Left-hand (LH) orientation — designed for the driver-side or left-side installation; bleeder screw positioned at the top for proper bleeding
• Forged billet aluminum body — lightweight yet exceptionally strong construction reduces unsprung weight without sacrificing rigidity
• High-temperature red powdercoat finish — corrosion-resistant and heat-resistant coating provides a clean appearance and long-lasting durability
• Racing-grade seals and hardware — compatible with high-temperature brake fluids (DOT 4/5.1 and racing fluids) for fade-free performance
• Bridge-bolt design — eliminates caliper flex and maintains consistent pad-to-rotor contact under extreme braking forces

The Wilwood XRS6R caliper is a purpose-built racing brake component, ideally suited for road racing, autocross, and high-performance street builds where superior stopping power and pedal feel are critical. As a left-hand unit, it is sold individually and is designed to be paired with its right-hand counterpart for a complete axle upgrade.
