Does anyone road race their 818r (or any 818) now? If so, what sanctioning body (SCCA, NASA, WRL, ChampCar, etc.) and what class?
What donor car did you use (year and model and engine size)?

Sorry if this is already answered, but my searches didn't turn up any threads about classing for road racing.
Answers to these kinds of questions would be a great sticky thread, in my (humble) opinion.

I currently race Formula 500 in SCCA, but am thinking about a different car that can do more (endurance racing, time trials, track days/nights, etc.)
