MMR Sport Suspension Upgrade for BMW F20 F21 F22 F23 2011-2020 - MMR34-0501FK - Our MMR Sport Suspension fast-road upgrade for BMW 1 & 2-Series F2x combines our MMR x Bilstein Sport Dampers with perfectly matched MMR Lowering Springs to transform both the appearance and handling dynamics of your car, whilst still retaining a beautifully ride quality. Give your car a whole new lease of life with the MMR Sport Suspension upgrade. We've meticulously struck a ride & handling balance that matches the very best thoroughbred German performance cars - tight, perfectly controlled yet unmistakably sporty. Many experts consider suspension development to be as much an art as a science. In truth, it's a bit of both. When it comes to a matched set of Sport Dampers and Lowering Springs at an affordable price, this non-adjustable fast-road kit solves the compromise between performance and comfort for keen BMW 1 & 2-Series F2x drivers. The kit combines the MMR Sport Damper kit - comprising two front and two rear Tri-Valve dampers - with a set of 4 perfectly-matched MMR Lowering Springs specific to the BMW 1 & 2-Series. These springs provide a drop at the front of 20mm whilst the rear sits lower by 30mm. Our track & race set-up experience on the F2x-platform has allowed us to develop this fast-road orientated damper exclusively in conjunction with industry-leaders Bilstein. The secret to our development with Bilstein has been to produce a set of shock absorbers with a damping curve that precisely matches the MMR Spring rate. The Sport Dampers feature a sophisticated dual tube design and low-pressure Nitrogen gas system that ensures the sophisticated ride and handling dynamics and sets them 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). The result? Together, the spring and damper setup we have reached gives a taught, sporty feel during high speed cornering on smooth surfaces yet always retains comfort on uneven surfaces. A little tighter than factory, sure, but never crashy or uncomfortable. In other words, appearance, handling and ride quality that's exactly how a good hot-hatch should be. Features The MMR Sport Suspension upgrade consists of: Two front and two rear MMR Sport dampers. Four MMR Lowering Springs, specific to BMW 1 & 2-Series F2x We strongly recommend a full 4-wheel alignment after fitment. The Sport Suspension kit is easily fitted by any experienced technician, and fitment is fully reversible should you ever wish to remove them.  Applications  Series  Model Code  Year Variant  Engine  1 Series  F20/F21 * 2011 - 2019 1-Series F20 / F21 All * 2 Series  F22/F23 * 2013 - 2020 2-Series F22 / F23 All * * Not applicable for any X-Drive models
