The Wilwood Aero4 is a radial mount four-piston brake caliper built to handle high braking loads in both road and track environments. Its forged aluminium body, internal fluid routing, and large rotor compatibility provide efficient and consistent stopping performance across a range of heavy-duty applications.Explore the key technical features and how they deliver practical benefits and real-world performance gains:Stress-Flow Forged Aluminium Body: Forged from a premium-grade aluminium alloy using a stress-flow process that aligns the grain structure with the caliper s shape, this feature increases material strength and fatigue resistance, resulting in a caliper that maintains structural integrity under high load without flexing or distorting.Internal Fluid Passages: Designed with integrated fluid channels that replace the need for external crossover tubes, this feature reduces the chance of line damage and simplifies installation, ensuring a cleaner layout and improved long-term reli
