Presenting the only solution for lowering your 650S.
Finally, a lowering solution for the McLaren 650S with Vehicle Lift. These springs were designed to lower a McLaren 650S equipped with Vehicle Lift by 1.0" in both the front and rear. These springs utilize the factory fixed spring perch system, retain the stock spring rate, and are tested to ensure they are 100% compliant with the factory on-board monitoring systems.
Since they are from H&R, you know they are the good stuff (we're talking a ISO 9001 certified facility, manufactured in Germany, made from special 54SiCr6 spring steel which has strength rated at 290,000 psi).
