Description

The Ksport Circuit Pro 3 Way coilover kit is engineered for enthusiasts and professionals demanding ultimate performance and durability in motorsports applications, including drifting, time attack, and circuit driving. Its extensive adjustability allows for seamless transition from track performance to street driving. Key features include external reservoirs that independently manage rebound and compression settings, along with nitrogen gas pressure. This system offers over 11,664 unique tuning combinations, enabling fine-tuned suspension setup. The 55mm Monotube shocks ensure consistent performance and heat dissipation, while the electroplated body provides corrosion resistance. Collars and upper mounts are constructed from hard-anodized 6061 aluminum with T6 treatment. This coilover system is designed with adjustable spring perches for ride height customization without affecting shock or spring travel. It also includes upgraded bumpstops to prevent bottoming out on uneven surfaces and an adjustable lower mount for maximum suspension travel. The front top mounts feature pillowball construction with camber adjustment, while the rear uses iron mounts without camber adjustment. The Ksport Circuit Pro 3 Way coilover kit is compatible with the 2014-2018 Mazda 3 BM models. It comes with a 12-month warranty covering manufacturer defects.
