Winning TT5/ST5 2005 RX-8 Race/Track Car

Posted by JohnSantiago about 5 months, 2 weeks ago

Up for sale is a 2005 Mazda RX-8 currently prepped for NASA ST5/TT5 competition, originally prepped for PWC TCA competition. Current record holder at Autobahn CC (south circuit, in TT5 and ST5) and National Corvette Museum (grand full circuit). This is the 2018 NASA Great Lakes regional championship winning car.

The car is very competitive in its class, extremely light on consumables, and since my ownership built to be reliable and easy to drive. Car has its 2019 annual inspection and current logbook (Time Trial). Recent dyno (05.20.19) shows only 2% power differential since initial build. This is a solid turnkey car that needs nothing; get in, turn the key, race!
