The Wilwood 140-16208 Forged Narrow Superlite 4R/ST rear disc brake kit is engineered to provide balanced, high-performance braking for unrestricted road race competition. This complete kit features forged aluminum four-piston radial mount calipers designed to match AERO6R/ST front brake systems while minimizing rotating and unsprung weight for optimal handling and acceleration.

Key Features:

• Forged Narrow Superlite 4R/ST Calipers: Forged aluminum construction with Type III Mil-Spec medium gray hard anodized finish for superior wear resistance and corrosion protection
• Thermlock® Pistons: Advanced piston technology reduces heat transfer from pads to caliper body, increasing fade resistance and extending component service life
• Internal Damper Springs: Controlled retraction system with high-temperature piston seals ensures consistent pedal height throughout racing sessions
• 13.00" Spec37 Alloy GT Series Rotors: Directional vane design with Dynamic Lug Mounting system to forged aluminum hats for optimal heat dissipation
• OE Compatibility: Caliper piston volumes matched for full compatibility with OE master cylinder output and ABS controls, or manual brake conversions with balance bar pedals
• Complete Hardware Included: Mounting brackets and premium grade fasteners for stock location installation with no modifications required
• Application-Specific Race Pads: High-temperature, high-friction race compound brake pads selected for optimal performance

This championship-proven braking system delivers the durability, heat management, and front-to-rear balance demanded by serious road racing applications. Installation requires separate purchase of stainless steel braided flexline kit ordered according to specific vehicle model year.
