The KartSim Digital Display Unit adds a steering-wheel-mounted display to compatible KartSim Pro Simulator configurations, giving the driver key information directly in their line of sight while driving. The display can show live driving data such as lap times, split and lap delta information, lap count, speed, RPM, and gear information where supported by the simulator configuration. This makes it easier to monitor performance during practice sessions without relying only on the main screen or external overlays. This upgrade is suited to drivers who want a more complete cockpit feel and a clearer view of essential session data. It is especially useful for structured testing, coaching, and repeated lap analysis on KartSim Pro Simulator setups.
