Circuit Pro 3-Way Coilover Kit

The Ksport Circuit Pro 3-Way Coilover kit represents Ksport's pinnacle of performance suspension engineering, meticulously developed and tested for motorsports applications including drifting, time attack, and circuit racing. The core innovation lies in its external reservoirs, which provide independent adjustment for rebound and compression, complemented by adjustable nitrogen gas pressure. With over 11,664 potential setting combinations, this coilover system allows for granular tuning to optimize vehicle dynamics. Built using aerospace-quality aluminum components, the Circuit Pro coilovers are equipped with 55mm monotube shocks. This design enhances heat dissipation and ensures consistent performance during demanding applications like endurance racing. The 36-way adjustable damping allows for precise fine-tuning of both compression and rebound simultaneously. Additionally, the system features adjustable lower mounts to maximize suspension travel and includes options for upper mounts, ranging from rubber to pillowball and Ksport's advanced pillowball mounts that incorporate camber and caster adjustment capabilities. Key specifications include front spring rates of 18 kg/mm and rear spring rates of 14 kg/mm. Each coilover system is individually dyno tested, with results available upon request to assist with tuning. Ksport offers a 12-month limited warranty on these coilovers. Fitment for this kit includes the Infiniti G37, G25, and Q60 models from 2014-2015 (V36 chassis, 2008-2013), specifically for Coupe and Sedan RWD variants, excluding convertible models. It also fits the Nissan 370z (Z34 chassis) from 2009-2018, excluding roadster models. Please note that Ksport Circuit Pro 3-Way kits are built to order, requiring an estimated 2-3 weeks for production and delivery.
