H&R RSS Coilover Kit – 2001–2006 BMW M3 / M3 Cabrio (E46) | S54

Elevate the already legendary handling of your 2001–2006 BMW E46 M3 or M3 Cabrio with the H&R RSS Coilover Kit — designed and tested on the legendary Nürburgring Nordschleife for the performance-minded driver who demands maximum vehicle feedback, flat cornering, and supreme directional control. The E46 M3 is widely regarded as one of the finest driver's cars ever produced — its near-perfect chassis balance, high-revving S54 inline-6, and precise steering make it an ideal platform for a precision coilover upgrade. The H&R RSS Coilover Kit lowers the center of gravity and reduces body roll to sharpen the E46 M3's already exceptional handling dynamics, while H&R's exclusive dynamic damper technology and fully threaded shock body provide precise ride height adjustment and a damping setup calibrated for the demands of the E46 platform.

Key Features

• Nürburgring-Developed: Designed and tested on the famous Nürburgring Nordschleife — the world's most demanding proving ground for suspension development — for a setup that delivers maximum vehicle feedback, flat cornering, and supreme directional control on the E46 M3 platform
