2003 - 2007 Infiniti G35 Ksport Circuit Pro 3 Way Coilover Kit - CNS260-C3

Ksport Circuit Pro 3 Way coilover kits provide the ultimate in adjustability for enthusiasts and professionals alike, who require maximum performance and durability. With years of engineering, testing and development, the Circuit Pro 3 Way coilover system has been perfected in virtually every facet of motorsports, ranging from drifting to time attack or circuit driving. The uncompromising range of adjustability on the Circuit Pro coilover System makes it possible to win at the track yet drive daily on the street as well. Each Ksport Circuit Pro coilover System has been dyno tested individually, and the results can be requested with the system at the time of purchase to aid in coilover tuning. The key component to the Circuit Pro coilover System is its utilization of remote reservoirs that provide separate adjustments for rebound and compression, as well as nitrogen gas pressure. With over 11,664 possible settings provided by each Circuit Pro coilover System, it is possible to leave no stone unturned in the quest for ultimate performance from your vehicle’s suspension system. In addition to adjustability, the added oil capacity provided by the remote reservoirs increase the system’s ability to dissipate heat, which leads 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 which allow adjustment of rebound, compression and nitrogen pressure independently. Circuit Pro damper kits come 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 and spring travel. Circuit Pro coilovers come standard with a 12-month warranty which covers manufacturer defects.
