In 2004 they absolutely dominated the competition winning every race except one and managing to set two world records in the process. Jason’s CRX has run a best time of 9.53@154mph making it the world record holder for fastest FWD street car without wheelie bars. Jason’s coupe managed a 9.61@149mph setting the record for the world’s fastest street coupe.
