MSS Sports Adjustable Spring Set - E9X M3 (Discontinued)

E9X M3 MSS Spring Kit:
Front Lowering: 0-30mm
Rear Lowering: 0-25mm
Finely-tuned adjustable lowering springs matched to your factory shocks!

MSS uses a stacked rear spring design combined with progressive-rate main springs to achieve high levels of comfort even with a lowered ride height. Two active springs and three distinct spring rates deal with a much wider array of situations than a single static spring rate. The stacked springs allow a moderate and comfortable ride thanks to a "soft" initial spring for minor bumps and road irregularities. The MSS approach with a triple spring rate is unique and is remarkably effective in real-world driving. We tested multiple cars with these springs and were genuinely impressed with how ride comfort improved over the factory suspension, even with a lowered ride height.

Spring rates are developed specifically for your chassis to retain as much ride comfort as possible, even with a lowered suspension. Ride height has been precisely engineered to work with the travel of the stock shock/strut and new bump stops are included that allow lowering with the proper shock travel.

Manufactured in the UK and TUV approved. Springs are made by Eibach with a lifetime warranty.

Lowering amounts will vary depending on factory suspension options. Do not exceed 30mm of lowering height and maintain a F:R rake of 5mm. Springs will settle into a final ride height after approximately 2,000 miles.
