- This kit has tested the combination of spring rate and damping force over and over again. By adjusting 30 levels of damping force, it can be used from street to high-speed truck.
- The IS-F is not possible to adjust front camber without upper camber arms. This kit has tested with aftermarket front upper camber arms and LSD, and setting the front camber to +3 degrees 30 in Fuji international speed way. The suspension kit committed the needs of a wide range of markets, from that track oriented spec to a daily driving.
