Kontrol Sport Coilover System

The Ksport Kontrol Sport Coilover System is an enhanced version of their popular Kontrol Pro coilovers, engineered for the Infiniti M35 and M45 RWD models from 2006-2010 with chassis code Y50. It features 36 levels of adjustable damping, enabling precise tuning for optimal handling and comfort. Compared to the Kontrol Pro, the Kontrol Sport offers 30% stiffer valving and spring rates, resulting in a more aggressive and direct feel, tighter cornering, and quicker response times, making it ideal for aggressive street driving and intermediate track use. Key specifications include front spring rates of 16 kg/mm and rear spring rates of 9.8 kg/mm. The coilovers utilize a Monotube High Pressure Design to reduce oil leakage and feature adjustable spring perches for ride height adjustment. The top mounts are constructed from aerospace-quality aluminum, with front and rear mounts offering no camber adjustment. The system includes a full set of four coilovers, with adjustable lower mounts to maximize suspension travel and dust boots to protect damper seals. Ksport provides a 12-month limited warranty with this product. The installation process benefits from adjustable lower mounts, allowing for maximum suspension travel. Buyers should note that while these coilovers offer significant performance enhancements, they are intended for aggressive street and intermediate track use, and professional installation or setup may be recommended for optimal performance and longevity.
