The SD4 Racing Wheel by Life Racing is an ergonomically shaped lightweight carbon racing wheel with an integrated high resolution 4.3″ display fully configurable and customisable switches and LED operation. Up to 10 buttons (including isolated radio button) and five multifunction rotary switches. There are options to include digital paddle levers for UP and DOWN gear change requests as well as two analogue progressive levers which can be used to control features such as automatic clutch operation. Two CAN2.0B buses, and twin Ethernet connections mean the SD4 retains the capability and flexibility to act as a central hub in a vehicles communication system.
