Kontrol Pro Full Coilover Kit with 36-Way Adjustable Damping

The KSport Asphalt Rally AR Coilover Kit is specifically engineered for the demands of asphalt rally competition and spirited driving on back roads, offering enhanced durability over standard street coilovers for the 2014-2019 BMW M4 (F83) RWD. These coilovers feature inverted monotube shocks with larger 55mm bodies and increased fluid volume for superior heat dissipation and consistent performance, even under aggressive use. Heavy-duty steel lower mounts provide robust protection during intense driving. This kit offers extensive adjustability to fine-tune your suspension setup. With 36-way adjustable damping, you can precisely control rebound and compression to match your tires, driving surface, and personal preference. The collars and upper mounts are constructed from hardened 6061 aluminum with T6 treatment, while the front pillowball top mounts include camber adjustment for optimal alignment. The adjustable spring perch allows for ride height customization. Key features include all-metal pillowball mounts for increased strength and responsiveness, electroplated bodies for corrosion resistance, and dust boots to protect damper seals. The spring rates are set at 16.0 kg/mm (896 lbs/in) for the front and 22.0 kg/mm (1232 lbs/in) for the rear, utilizing linear springs. This coilover system is designed for the 2014-2019 BMW M4 RWD (F83) models. An important fitment note specifies that these coilovers are for Convertible models only.
