The MMX Performance G90 / G99 M5 Lowering Spring Set transforms the stance and dynamic response of BMW's latest M5 super sedan and super wagon without compromising the long-distance refinement that defines the platform. Engineered specifically for the new G90/G99 chassis and its hybrid xDrive powertrain, these springs lower the centre of gravity and tighten body control while leaving every drive mode usable.
Each spring set delivers a balanced front and rear drop that closes up the wheel arches, reduces body roll, and sharpens turn-in feel. The progressive spring rate keeps low-speed compliance smooth (actually feeling more composed around town) while the chassis comes alive at speed with crisper, more direct response through the corners. Push too low or too firm and you risk upsetting the OEM damper match; MMX specifically engineers each tune to work in harmony with both static and Adaptive M dampers.
The G90 Sedan and G99 Touring are tuned independently (different SKUs, different rear drop figures) to reflect each chassis's weight distribution and handling priorities. Select your variant from the dropdown.
One of MMX's best-selling upgrades, and the ideal first mod for the new M5.
