The replacement MMR Sport Dampers will bring a whole new lease of life to your car at a great price. Suitable for either standard springs or MMR Lowering Springs, your car will ride and handle better than ever. Developed exclusively with Bilstein, this kit of four Sport Dampers make a great fast-road orientated upgrade especially for older or higher mileage cars.

When it comes to suspension upgrades at an affordable price, the compromise between performance and comfort has been a persistent dilemma for keen drivers. Our motorsport suspension expertise has allowed us to develop this high quality, fast-road orientated damper kit exclusively in conjunction with industry-leaders Bilstein.
Throughout our development process we’ve ensured that the MMR Sport Dampers are suitable for use with either our popular MMR Lowering Springs or the standard factory springs.
The setup we have chosen gives a taught, sporty feel during high speed cornering on smooth surfaces yet always retains factory comfort on uneven surfaces. It’s our sophisticated dual tube design and low pressure Nitrogen gas system that ensures the sophisticated ride and handling dynamics of the MMR Sport Dampers. They make a particularly effective upgrade for older or higher mileage cars where the original factory dampers have worn, losing their original damping characteristics.
The addition of Nitrogen gas into the system eliminates oil foaming when the oil is hot, which is the main cause of shock fade in hard driving. Our design limits the heat build-up internally, ensuring the oil performs better for longer.
Intelligent Tri-Valve technology sets our Sports Dampers apart from standard OEM dampers. Each damper features three hydraulic valves inside: bump, rebound and a main valve, controlled by low and high speed shaft frequencies (smooth and rough road conditions).
All of which guarantees greater stability, control, and a beautiful taught ride quality - and therefore driving pleasure. And isn't that what it's all about?

Built exclusively for MMR by Bilstein, the longevity far exceeds the OEM units and many rival aftermarket dampers of similar value due to the higher quality oil used in the MMR Sport Dampers. The bodies and bracketry of the Sport Dampers are made of mild steel, uniquely finished in the MMR satin silver with shaft in hardened chrome.
Note: not suitable for X-Drive models.
