Wilwood ST AERO6 Caliper 1.75/1.38/1.38 1.25

The Aero6/ST forged six-piston caliper provides heavy-duty stopping power for road or track. It features race technology with widespread adaptability, radial mounting, multiple piston volume options, and supports rotor diameters from 12.88" to 15.00". This new Aero6 innovation redesigns the W4A / W6A series with internal fluid ports, eliminating external cross-over tubes and a massive center bridge. It includes Thermlock piston technology and Wilwood’s Type III anodize coating. Aero6/ST calipers use .80” thick 6620 pad plates for extended life in endurance racing. The stress-flow forged body is made from a premium aluminum alloy billet, aligning the metal's internal grain structure for superior clamping efficiency and strength against fatigue, stress, and distortion under load.
