My main vehicles are a 99 Miata, 93 RX7 and a DSR.
Miata is stock except for some valved Konis and a Monza catback. It is a competitive Stock SOLO car.
The RX7 has been mine since 1997. Lots of mods since it has been a track car for a few years. Ran it mostly at Summit Point, VIR, Watkins Glen and Road Atlanta. Suspension, rollbar, intake and exhaust plus a lot more. Great car.
The DSR is a 1998 AMAC D Sports Racer which I race in SCCA competition. Power is from a 2005 GSXR 1000cc engine dropping 200 at the wheels.
I am also heavily involved in the Time Trials program down here
