Wilwood 120-13301 Aero6-ST Right-Hand Six-Piston Radial Mount Caliper Anodized

The Wilwood Aero6-ST is a forged six-piston radial mount brake caliper engineered to deliver exceptional stopping power for both street and track applications. This right-hand caliper builds on the proven W6A series platform, incorporating modern race technology into a versatile, widely adaptable body design.

Key Features:

• Radial mount design with compatibility for rotor diameters ranging from 12.88" to 15.00", accommodating a wide range of heavy-duty braking setups
• Stress-flow forged aluminum alloy body — the forging process realigns the metal's internal grain structure to follow the contour of the caliper, eliminating weaknesses caused by straight-block billet machining
• Internal fluid ports eliminate external fluid cross-over tubes and the bulky center bridge assembly found on older designs, reducing weight and improving fluid routing
• Thermlock piston technology insulates the brake fluid from heat generated at the rotor and pad interface, reducing vapor lock risk under sustained heavy braking
• .80" thick 6620 pad plate (ST configuration) provides increased pad material volume for extended pad life in high-heat endurance racing environments
• Type III hard anodized finish provides superior corrosion resistance and a durable, professional appearance
• Multiple piston volume options allow tuning of brake bias and pedal feel to suit specific vehicle weights and braking demands

The superior clamping efficiency and fatigue resistance of the stress-flow forged body make the Aero6-ST an ideal choice for road racing, time attack, performance street driving, and any application demanding reliable, consistent braking performance under load. Sold individually as a right-hand caliper.
