  • 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.
  • We recommend a damping force setting should be set at level 6 for high-speed circuits such as FSW and level 15 - 30 for street use.
  • This kit has a "Preload valve system" that is popular with HKS HIPERMAX IV GT 20 SPEC, it achieves comfortable daily driving and smooth absorption of road information with a high rate spring.
