APEX Pro = Instant Feedback. Why use the APEX Pro? We already use our AiM MXG or AIM Solo to gather our complete Vehicle Health and Driver Performance data, but we need instant performance data feedback. Predictive lap times are very important to a successful lap, we all know that, but APEX Pro gives us maximum cornering potential, instantly. Are you using 100% of your performance envelope? APEX Pro uses 12,000 data points/second to show your true cornering potential, every corner, every lap.
