Wilwood 120-16890-RD Forged Disc Brake Caliper - Aero6 6-Piston Red

The Wilwood Aero6 Forged Six-Piston Brake Caliper (PN: 120-16890-RD) delivers serious stopping power for both street and track applications. Featuring radial mounting, multiple piston volume options, and compatibility with rotor diameters ranging from 12.88" to 15.00", the Aero6 is engineered to handle the most demanding heavy-duty braking requirements.

Key Features:

• Six-piston forged aluminum construction for maximum clamping force and reduced weight
• Stress-flow forged premium-grade aluminum alloy body — forging realigns the metal's internal grain structure to follow the contour of the caliper, eliminating stress points caused by traditional billet machining
• Superior fatigue and distortion resistance under extreme braking loads and high heat
• Radial mounting design for precise, repeatable brake feel and easier pad replacement
• Compatible rotor diameter range: 12.88" to 15.00"
• Multiple piston volume options allow fine-tuning of brake bias and pedal feel
• Red anodized finish for corrosion resistance and a high-performance appearance
• Suitable for heavy-weight performance street, road course, and competition track use

The Aero6's stress-flow forging process sets it apart from conventional machined billet calipers. By allowing the metal's grain structure to flow naturally within the caliper's contour, Wilwood achieves a body with superior clamping efficiency and long-term structural integrity — critical attributes for calipers subjected to repeated high-stress braking events.
