Description

The Ksport Circuit Pro 3-Way Coilover kit represents the pinnacle of suspension technology for discerning drivers and racers. Engineered through extensive testing across diverse motorsports disciplines including drifting, time attack, and circuit racing, this system delivers exceptional performance and unwavering durability. Its broad adjustability spectrum ensures that the vehicle can achieve track-winning performance while remaining suitable for everyday driving. The core of the Circuit Pro system lies in its remote reservoirs, which provide independent control over rebound and compression damping, alongside nitrogen gas pressure adjustment. This granular control, offering over 11,664 potential settings per coilover, allows for meticulous fine-tuning of the suspension to achieve ultimate performance. The enhanced oil capacity within these reservoirs significantly improves heat dissipation, guaranteeing consistent performance during demanding endurance races or extended track sessions, and maintaining stability throughout long heat cycles. These advanced features, combined with robust 55mm Monotube shocks, ensure both longevity and reliable performance. Customization is further extended through a variety of available external hardware components. Buyers can select from rubber upper mounts, pillowball mounts, or Ksport's advanced pillowball mounts, which include camber and caster adjustment capabilities, enabling a completely tailored suspension setup. Each system is individually dyno tested, with results available upon request to assist with fine-tuning. Please note that Ksport Circuit Pro 3-Way kits are built to order, requiring a production and delivery time of 2-3 weeks. This kit is designed to fit specific Subaru Impreza WRX STI models from 2005-2007. While the product page indicates fitment for a wide range of vehicles, it is crucial to verify compatibility for your specific year, make, model, and trim using the provided search tool. Ksport products are designated for off-road use only, unless explicitly stated otherwise, and are intended for competition or racing sanctioned by a recognized organization.
