J-Damper Short for Jounce-Damper although technically it should be called a Jounce-Inerter, the term J-Damper was coined to keep the technology secret for as long as possible. It's purpose is to reduce the effect of the spring and Damper oscillations and thus help the car to retain a better grip on the road. Jounce Specifically refers to the compression stroke in a suspension system when a wheel hits a bump and is moved upwards relative to the chassis. The opposite movement is termed "rebound". Jump Start When a driver moves off his grid position before the five red lights have been switched off to signal the start. Sensors detect premature movement and a jump start earns the driver a penalty.  |
