Can definitely do an AMA, but not sure how interesting it would be.
We have built multiple kinds. We have build engines/cars for Rolex GrandAm, Drifting (Formula D), Land Speed Racing (we actually hold a bunch of records in our class), King of Hammers/Baja type off-road (engines/wiring only, not chassis), and then the more casual type stuff for the weekend warrior types (autoX, desert toys, etc).
