AERO4 Big Brake Lug Drive Front Brake Kit (Race)

Aerolite four piston calipers are coupled with the high heat capacity of dynamically mounted 14.00" Spec37 alloy rotors to provide consistent, responsive braking for Corvette race cars, autocross, and track day cars using Corvette suspension. GT rotors with 72 staggered directional vanes shed heat and float on lightweight forged aluminum hats via an innovative, dynamic lug-drive mount system to further reduce thermal stresses. This kit comes complete with high temperature, high friction, BP-30 SmartPads selected specifically for exceptional driver control with DOT tires and limited downforce.

The radial-mount Aerolite caliper uses a forged aluminum body with type III Mil-Spec hard anodized finish and a closed bridge to reduce deflection. The race version features a wide body for 20mm pads, providing longer service life on track even with high speed and heavier cars. Aluminum Thermlock pistons with stainless steel shields further protect brake fluid from heat compared to the aluminum or steel pistons found in OE calipers. Internal springs and high-temperature piston seals reduce piston knockback for a more consistent pedal feel.

Caliper pistons are sized for complete compatibility with the factory master cylinder and ABS controls. For dedicated competition use, manual brake conversions with balance bar pedals are also possible. Mounting brackets with premium-grade hardware secure the calipers in the stock location. Kit requires a stainless steel braided flexline, sold separately, specific to the model year.
