Wilwood AERO4 Radial Mount Calipers
Wilwood AERO4 radial mount calipers deliver heavy-duty stopping power for the road or track. They incorporate race technology into a body design with widespread adaptability. Radial mounting, two options for piston volume, and a wide range of rotor diameters give these calipers the versatility necessary to suit all types of heavyweight braking requirements. Wilwood Aero bodies are stress-flow forged from premium-grade aluminum alloy billet, to create calipers with superior clamping efficiency and ultimate strength against fatigue, stresses, and distortion under load. They are equipped with either stainless or high-temperature Thermlock pistons. For stopping power you need, trust Wilwood Aero4 radial mount calipers.
