Wilwood 120-15598 Forged Four Piston Brake Caliper - Aero4-DS

The Wilwood Aero4-DS forged four piston caliper delivers heavy-duty stopping power for street and track applications. Engineered with advanced race technology, this caliper features a versatile design with radial mounting capability and multiple piston volume configurations to accommodate rotors ranging from 12.88" to 15.00" in diameter.

Key Features:

• Stress-flow forged construction from premium grade aluminum alloy billet
• Four-piston design for superior clamping force and balanced pad wear
• Radial mount configuration for enhanced structural rigidity
• Compatible with rotor diameters from 12.88" to 15.00"
• Multiple piston volume options for customized braking performance
• Anodized finish for corrosion resistance and heat dissipation

The stress-flow forging process realigns the metal's internal grain structure to follow the contours of the caliper body, eliminating the weaknesses inherent in traditional billet machining. This advanced manufacturing technique results in exceptional clamping efficiency, superior strength, and outstanding resistance to fatigue, stress, and distortion under extreme braking loads.
