For anyone who thinks they are a good driver, you NEED something like traqmate. Our friend Richard from TRAQMATE.jp in Japan set up the Traqmate system for TG-Racing to use in their prelude. It has some cool features like G-Sensors, car information pickups and most importantly video.
This video shows a theoretical best lap of me at Japan's Ebisu Circuit in the TG-R Prelude.
