Nice, I've run Lemons four times now but all at Sonoma. We keep wanting to build a car and run more of the West Coast races but having the time to do so has prevented such ventures. Came really close to buying a $400 IROC Z Camaro lol! The E36 is probably the perfect chassis for low-buck enduros. It's cheap, easy to work on, has great parts availability, and is fun to drive.
It would be cool to see the ZX at a track event sometime. If there are ever any old Z's at the days I go to, they're always S30s. I run mostly with NASA but also Trackmasters and Speed Ventures. Once in a while, I'll do a day with some other random club. Let us know if you sign up for any!
