Circuit Pro 3 Way Adjustable Coilover Kit

The Ksport Circuit Pro 3 Way Adjustable Coilover Kit represents the pinnacle of KSport's track-focused suspension offerings for the 1998-2002 BMW Z3 RWD. This advanced system provides granular control over your vehicle's handling characteristics with three distinct adjustment knobs for high-speed compression, low-speed compression, and rebound damping. This allows precise tuning of chassis reaction to curbs, stability in fast sweepers, and response during braking, all independently adjustable. Engineered for serious track drivers and race teams, the Circuit Pro kit enables you to extract maximum performance from your BMW Z3. The inclusion of external reservoirs ensures ample oil volume and superior heat dissipation, crucial for extended track sessions. Its monotube design guarantees consistent damping performance, making your data logging more reliable. While built for racing, these coilovers can be dialed back for street use. Key features include 36 levels of damping adjustment, offering 11,664 possible tuning combinations to fine-tune your setup. The kit incorporates stiffer spring rates and shock valving, coupled with a 20-30mm shorter shock stroke and upgraded bumpstops to prevent bottoming out. Construction utilizes 6061 aluminum with T6 treatment for collars and upper mounts, ensuring durability and responsiveness with all-metal pillowball mounts. The adjustable spring perch allows for ride height customization, and the electroplated body provides corrosion resistance. Important fitment notes indicate that all suspension products are designed for 2WD vehicles unless otherwise specified. This kit is not compatible with OEM electronic damping control systems unless explicitly stated. The fitment is confirmed for 1998-2002 BMW Z3 RWD models, including the M Roadster.
