This high-performance Brembo 4-piston retrofit kit is a premium upgrade for the E39 and E46 chassis, including the M3. It replaces the factory single-piston sliding calipers with a fixed-piston Brembo architecture, providing significantly shorter braking distances and a firm, mechanical pedal feel. This set is in excellent condition, fully inspected, and ready for installation.
