Kirk Knestis is looking for a co-driver in his very fast ITB Golf, but he is looking for a renter, not a coach... still, if you are interested he is Knestis on this (and most other) sites.
Unfortunately I'm one of those guys who actually does the math so knows what it costs to go racing, so yeah - I'd need actual green. I can still put a person on track for half of a 3-hour enduro for less $$ than they would have to spend to do it themselves with the same level of preparation...
