The MMR Performance Lowering Spring Kit for the G87 M2 RWD is one of the most popular suspension upgrades available. It delivers the ideal blend of improved handling, enhanced aesthetics and excellent ride comfort.
Lowering the M2’s center of gravity noticeably sharpens chassis behavior by reducing body roll and improving stability without compromising everyday drivability. The carefully selected progressive spring rates maintain factory ride quality at slow speeds and actually feel smoother over uneven surfaces. When you push harder through the corners, the G87 responds with quicker turn-in, improved balance and a more connected driving feel.
Visually, this upgrade instantly transforms the stance of the M2. Eliminating the excessive wheel arch gap creates a more aggressive, factory-finished look that complements the car’s performance character.
Go lower or stiffer than these springs and the dampers will struggle to keep up, resulting in a harsh, bouncy ride. MMR’s rates and height settings are engineered specifically to work with the factory damper system so performance and comfort remain in harmony.
Finished in MMR Metallic Gunmetal Grey, these springs are fully compatible with both standard and Adaptive M dampers.
