Description

Its design incorporates large 44mm pistons, which increase the shock oil volume to effectively manage heat during prolonged, demanding use. The system offers 36 distinct levels of damping adjustment, allowing for simultaneous fine-tuning of both compression and rebound. This precise control enables drivers to optimize handling characteristics and comfort according to specific track conditions and personal preferences. The front pillowball top mounts feature integrated camber adjustment, allowing for precise alignment tuning directly at the coilover. The rear top mounts also utilize pillowball construction for a more direct connection to the chassis, providing enhanced driver feedback. Height adjustment is managed through an adjustable lower mount, preserving full suspension travel even when the vehicle is lowered. The coilovers are constructed from lightweight and durable 6061 billet aluminum for corrosion resistance, with a zinc-electroplated steel shock body to further protect against the elements. The internal valving is meticulously matched to the spring rates (12kg front, 9.8kg rear) for optimal ride quality and reliability. This Ksport system employs a Monotube design, which separates gas and oil to improve heat dissipation, enable finer damping adjustments, and reduce aeration and cavitation compared to twin-tube designs. This results in a more consistent and refined ride. The product is noted to allow vehicles to achieve OEM height levels in some applications, with the ability to lower up to 3 inches from OEM for optimized rally setups, accommodating potential sanctioning body ride height regulations. This coilover system is specifically designed for the 1999-2005 BMW 3 Series E46, including models such as the 323i, 323Ci, 325i, 325Ci, 328i, 328Ci, 330i, and 330Ci, and includes wagon variants with true rear coilovers. It is also compatible with the 2001-2005 BMW M3 E46.
