Product Details

The KSport Circuit Pro 3 Way Adjustable Coilover Kit is the top of the KSport track-day ladder for the 2004-2009 Mazda 3. Three independent knobs separate high-speed compression, low-speed compression, and rebound — so you can control how the chassis reacts to curbs, how it settles through a fast sweeper, and how it recovers from a hard braking zone, all without touching the other two axes.

For serious Mazda 3 track drivers and race teams, the Circuit Pro delivers the setup flexibility you need to get the absolute last tenth out of a lap. Remote reservoirs provide the oil volume and heat capacity required for long sessions, and the monotube design gives the consistent performance that makes your data meaningful. This is a full race coilover you can still dial back for the drive home.
