Circuit Pro 3 Way Adjustable Coilover Kit

The KSport Circuit Pro 3 Way Adjustable Coilover Kit is the ultimate track-day upgrade for the 1996-2002 BMW Z3 4-Cyl Non-M Power. This system provides unparalleled tuning flexibility with independent control over high-speed compression, low-speed compression, and rebound damping, allowing precise adjustments to chassis reaction, cornering stability, and braking response. The monotube high-pressure design guarantees consistent performance and effective heat dissipation. With 11,664 possible tuning combinations and 36 levels of damping adjustment, drivers can meticulously dial in their suspension setup. Construction highlights include 6061 aluminum collars and upper mounts with T6 treatment for enhanced hardness. The kit utilizes pillowball mounts for increased strength and responsiveness, adjustable lower mounts for maximum suspension travel, and upgraded bumpstops to prevent bottoming out. The electroplated body provides corrosion and rust protection. Spring rates are set at 16.0 kg/mm (896 lbs/in) for the front and 10.5 kg/mm (588 lbs/in) for the rear, utilizing linear springs. Important fitment notes: This kit is designed for 2WD vehicles only. It is not compatible with OEM electronic damping control systems (EDC, DDS, etc.) unless explicitly stated, and aftermarket coilovers are generally not compatible with these factory systems. The specific fitment is for the 1996-2002 BMW Z3 4-Cyl Non M-Power models. Product images may not represent the actual SKU.
