The G42 M240i xDrive is one of the most capable sport coupes in BMW's current lineup, and Dinan's Performance Spring Set takes its chassis tune further with a 7/8" (22mm) drop and a 24% increase in spring stiffness across both axles. The front springs use a dual-rate design; the rear runs linear rate — a deliberate pairing that delivers progressive feel up front with predictable breakaway at the rear.
Springs are CNC wound from high-tensile chrome silicon wire and shot-peened for stress relief. The kit is engineered for compatibility with the factory Adaptive M Suspension electronic shocks, so you keep the factory damper adjustment range while running a significantly sharper spring tune.
