Why there’s no single number
Ksport coilovers use a threaded-body design, so ride height is adjustable within a range engineered for that specific kit and chassis — a Civic Kontrol Pro kit and a Supra Circuit Pro kit are not built to the same range, and different tiers on the same car (Kontrol Pro vs. Kontrol Sport vs. Circuit Pro) commonly differ too.
Where to find your kit’s actual range
The confirmed lowering range is listed on each specific product’s page for your vehicle. Look up your car on the coilover kits section, or contact support with your vehicle and kit if you want it confirmed before ordering.
