The BMW M Performance Height Adjustable Suspension Kit for the G8X M2, M3, and M4 provides a factory-engineered lowering solution that preserves the full functionality of BMW's Electronic Damper Control (EDC). Developed by BMW M Performance, this kit replaces the factory spring perches with precision-machined, threaded height-adjustable perches front and rear, allowing a 5–20 mm ride height reduction without compromising the adaptive damping system. It is the definitive OEM-grade suspension upgrade for G8X owners seeking a lower stance without sacrificing ride quality or electronics compatibility.
The kit includes threaded height-adjustable spring perches for both axles, along with strengthened and shortened bump stops and protective shock sleeves designed to safeguard the factory OEM dampers throughout the adjustment range. All components meet BMW M Performance engineering standards and are fully EDC-compatible, meaning the Active M Suspension modes remain fully operational after installation.
