MMR Performance Lowering Springs Kit for BMW 3 Series G20 M340i xDrive Saloon/Sedan (2018+) - 30mm Drop Progressive Sport Suspension Springs, OE Shock & Adaptive M/EDC Compatible - AWD Front & Rear Coil Spring Set

Sport Lowering Spring Kit for BMW G20 M340i xDrive Saloon

Give your G20 chassis the stance, grip and confidence it deserves. This MMR progressive-rate coil spring set lowers your BMW M340i xDrive by around 30 mm front and rear, delivering a lower centre of gravity, tighter body control and sharper steering response while keeping day-to-day comfort intact on British roads.

If you want the clean, purposeful look that deletes that annoying wheel arch gap without ruining ride quality, these sport springs are the sweet spot. Progressive coils mean supple compliance at urban speeds and composed control when pressing on, so your fast 3 Series feels more planted, more responsive and more fun everywhere.

Key highlights

• Approx 30 mm ride height reduction front and rear for a level, aggressive stance on the G20 saloon
• Progressive-rate design for improved body control and roll resistance with comfortable road manners
• Works seamlessly with factory shock absorbers, including Adaptive M electronic dampers and standard units
• Tuned specifically for xDrive all-wheel drive models to complement OE damper calibration
• Durable Metallic Gunmetal powder coat finish for long-term corrosion resistance
• Removes the factory arch gap to achieve the OEM-plus look enthusiasts want
