Kontrol Sport Coil-over Kit

The KSport Kontrol Sport Coilover Kit is engineered to transform the driving dynamics of the 2014-2019 BMW M4 RWD (F83) convertible. This system is designed for enthusiasts seeking a more track-focused setup, offering spring rates and shock valving that are 20-30% stiffer than the Kontrol Pro models. This increased stiffness translates to superior roll control, sharper turn-in, and improved stability, making it ideal for spirited driving, autocross, or track day use, without sacrificing street drivability. Featuring 36 levels of damping adjustment, the Kontrol Sport coilovers allow for precise tuning of both compression and rebound to match handling preferences and comfort needs. The kit includes adjustable spring perches for customizable ride height, enabling a lowered stance of up to 4 inches, and adjustable lower mounts to ensure maximum suspension travel. The use of 6061 billet aluminum for mounts and other components ensures durability and resistance to corrosion, while the electroplated steel shock bodies provide further protection against the elements. These coilovers utilize a monotube high-pressure design for enhanced performance, better heat dissipation, and consistent damping. Further enhancing performance and adjustability, the front pillowball top mounts incorporate camber adjustment, eliminating the need for separate camber kits. Some applications also feature advanced upper pillowball mounts offering independent camber and caster adjustment. The rear features aluminum mounts without camber adjustment, and the system is designated as a "True Rear Coilover." All KSport Kontrol Sport coilovers are backed by a 12-month limited warranty.
