Wilwood 140-16181 Front Disc Brake Kit Aerolite 4-Piston 14" Spec37 GT Rotor Race

The Wilwood 140-16181 is a complete front disc brake kit engineered for high-performance Corvette race cars, autocross competitors, and track day builds using Corvette suspension geometry. Pairing radial-mount Aerolite four-piston calipers with 14.00" Spec37 alloy GT rotors, this kit delivers consistent, fade-resistant stopping power under sustained high-heat racing conditions.

Rotor Technology:

• 14.00" diameter Spec37 alloy GT rotors with 72 staggered directional vanes for maximum heat dissipation
• Dynamically mounted on lightweight forged aluminum hats via an innovative lug-drive mount system
• Floating rotor design minimizes thermal stress and reduces warping under race conditions

Aerolite Caliper Features:

• Forged aluminum caliper body with Type III Mil-Spec hard anodized finish for corrosion resistance and durability
• Closed bridge design reduces caliper deflection for a more precise, consistent pedal feel
• Wide-body race configuration accepts 20mm brake pads for extended service life under high-speed and high-load track use
• Aluminum Thermlock pistons with stainless steel shields provide superior heat insulation versus standard aluminum or steel OE pistons
• Internal springs and high-temperature piston seals minimize piston knockback for consistent pedal response

Brake Pad & System Compatibility:

• Includes BP-30 SmartPad compound — specifically selected for exceptional driver control with DOT tires and limited downforce applications
• Caliper piston sizing is fully compatible with the factory master cylinder and OEM ABS controls
• Manual brake conversion with balance bar pedals is supported for dedicated competition use

Kit Includes:

• Aerolite four-piston calipers (both sides)
• 14.00" Spec37 alloy GT directional vane rotors with forged aluminum hats
• Caliper mounting brackets with premium-grade hardware
• BP-30 SmartPad brake pads

Note: A stainless steel braided brake flexline, sold separately and specific to the model year, is required to complete the installation. Mounting brackets position the calipers in the factory location for a clean, stock-style fitment.
