Wilwood 140-13882 Aero6 Big Brake Front Kit Race 14-Inch Slotted Rotors

The Wilwood 140-13882 AERO6 Big Brake Front Kit is engineered specifically for dedicated road racing competition. This championship-proven system pairs six-piston AERO6R/ST calipers with 14.00" Spec37 alloy GT series directional vane rotors for maximum stopping power and thermal management under the most demanding race conditions.

AERO6R/ST Six-Piston Calipers

The forged aluminum caliper bodies feature a Type III Mil-Spec hard anodized finish in medium gray, delivering superior wear resistance in piston bores and outstanding resistance to abrasion and corrosion. The updated AERO6R/ST design incorporates a wider-than-standard body accommodating 20mm thick brake pads, significantly increasing pad volume for extended service life during long race stints.

Thermlock® Piston Technology

Thermlock® pistons actively reduce heat transfer from the pads to the caliper body, fluid, and seals — directly combating brake fade and extending the service life of all caliper components. Internal damper springs combined with high-temperature, controlled-retraction piston seals ensure a consistent, repeatable pedal feel from the first lap to the last.

Rotors, Hats, and Mounting Hardware

The 14.00" diameter Spec37 alloy GT series directional vane rotors are dynamically mounted to OE hubs using weight-saving forged aluminum hats. Both the hats and calipers receive the same hard anodized finish for consistent wear resistance at all load-bearing surfaces. Radial mount brackets and all premium-grade fasteners are included, securing the calipers to the spindles in the OE stock location with no modifications required.

Race-Ready Pad and Brake Line Package

Each kit is completed with high-temperature, high-friction race compound brake pads selected specifically by application, along with stainless steel braided flex lines for a complete, race-ready installation out of the box.

OEM and ABS Compatibility

Caliper piston volumes are matched for full compatibility with the OE master cylinder output and ABS controls. The system is also fully compatible with manual brake conversions to balance bar pedal setups using appropriately sized master cylinders.
