Dinan's Performance Spring Set replaces the factory coils on the G42 M240i xDrive with two front dual rate springs and two rear linear rate springs, calibrated for a 24% increase in stiffness front and rear. The set lowers the car 7/8 inch (22mm) at both ends for improved suspension geometry and a more aggressive stance, while staying compatible with the factory electronic Adaptive M Suspension. Each spring is CNC wound from high tensile chrome silicon wire and shot-peened for stress relief, then preset to prevent sag, reducing body roll and sharpening steering response. The Ride Quality and Handling Kit is sold separately.
