Performance Trends Software and Electronics for Circle Track and Road Racing

Computer Programs and Data Loggers for Circle Track and Road Racing Performance.

Performance Trends has a wide variety of software programs that can help you with your vehicle. Cricle Track Analyzer can help you improve your cars performance on the track. Plus we have other programs dedicated to Racing Performance. We also have programs to help you with Suspension Setup and other components on your vehicles. And don't forget about Engine Analyzer our Engine Design Software to help predict what changes will improve performance. Plus we have our DataMite systems to record data from your vehicle or your engine.

Circle Track Analyzer v3.6 Computer Program to Simulate, Setup, Predict and Analyze Race Car Performance (including Late Models, Modifieds, Sprint Cars, Midgets, Go Carts, etc.) on Circle (oval) Track.  This program has our Roll Center Calculator completely built in as the Front Suspension Screen. It also has Rear Suspension, Track Specs, Engine Specs (power curve) and Vehicle Specs screens.
