Applications

Clear performance improvements can be made regardless of the type of vehicle, including SUVs and EVs.

Effects of application to SUVs

Performance Dampers have been highly evaluated thanks to their wide adoption in passenger vehicles with “monocoque frame” chassis. We have also found through demonstration tests using a Japanese made SUV that Performance Dampers can improve handling and ride comfort even in “ladder frames” often used in SUVs.

Effects of application to EVs

We measured the sound inside an EV while driving it around the paddock of a test course with and without Performance Dampers. Our demonstration test showed that even EVs, which have no engine noise and are already very quiet, became even quieter inside the vehicle. In EVs, Performance Dampers contributes to both quietness and handling.
