Ksport Circuit Pro 3Way coilover kits provide ultimate adjustability for enthusiasts/professionals alike, who require maximum performance and durability. With years of engineering, testing and development, the Circuit Pro 3Way coilover system has been perfected in virtually every facet, ranging from drifting to time attack or circuit driving. Uncompromising range of adjustability makes it possible to win at the track yet drive daily on the street. Each Ksport Circuit Pro coilover System has been dyno tested individually, and results can be requested with the system at the time of purchase to aid in coilover tuning. The key component to the system is its utilization of remote reservoirs that provide separate adjustments for rebound/compression, as well as nitrogen gas pressure. With over 11,664 possible settings provided system, its possible to leave no stone unturned in the quest for ultimate performance from your vehicle's suspension system. In addition to adjustability, added oil capacity provided by the remote reservoirs increase the system's ability to dissipate heat, leading to improved performance over long periods such as endurance or tarmac racing, in addition to consistent performance throughout long heat cycles. These features, paired with 55mm Monotube shocks, ensure maximum durability and consistent performance. Ksports Circuit Pro damper kits come standard with external reservoirs that allow adjustment of rebound/compression/nitrogen pressure independently. (certain vehicles may only have front reservoirs if the vehicle does not have enough allotted space to fit reservoir in the rear.) Also comes with upgraded bumpstops to prevent the shock from bottoming out over uneven pavement or harsh road conditions. Most of our coilovers feature the ability to adjust your ride height without affecting the shock/spring travel. You can set desired ride height without having to worry about bottoming out the shock. 12-mo warranty covering manufacturer defects.
