Description
Will this brake kit fit my vehicle?
Wilwood Aero Brake Kits are designed as bolt-on upgrades, but always confirm specific vehicle fitment before purchase to ensure seamless integration.
Can I retain my factory parking brake with this big brake kit?
Absolutely, these AERO4 Big Brake rear axle kits are engineered to use the OE parking brake assembly for complete functionality.
Wilwood Aero Brake Kits deliver significantly improved braking performance and heat dissipation, especially for street performance and track use with an 8/10 score. Featuring AERO4 calipers and oversized rotors, these bolt-on big brake kits provide superior stopping power for demanding maneuvers. Experience confident, enhanced braking with this expertly engineered big brake kit.
What Owners Say
Owners and enthusiasts consistently praise the Wilwood Aero brake kit for delivering noticeably improved pedal feel and fade resistance over factory brakes, with multiple track-focused drivers highlighting the more solid and responsive pedal characteristics. Fitment receives strong marks across C5 and C6 Corvette applications, though one installer noted receiving C6 GS brackets that required verification for proper compatibility. The value proposition stands out particularly well, with the complete kit costing less than single-axle alternatives from Brembo or Stoptech while accommodating both C6 Z51 and Z06 OEM-sized rotors. The consensus among the Corvette community establishes this as a performance upgrade that meaningfully enhances braking consistency without the premium pricing of competing big brake kits.
