Dinan Performance Lowering Spring Set - BMW M5 (E39) 2000-2003

Dinan's Performance Spring Set replaces the factory coils with carefully calibrated rates that lower the E39 M5 by 1/4 inch front and rear for tighter suspension geometry and a more aggressive stance. Each spring is CNC wound from high tensile chrome silicon wire, shot-peened for stress relief, and preset to resist sag over the life of the car. The stiffer rates reduce squat under acceleration and dive under braking while cutting body roll, sharpening steering response and improving grip at high speed.
