I think you may be off in your target demographic. A $30k car all in for an entry level race car is steep. Combine that with a target toward a younger age demo and it's going to be more difficult to draft racers. A lot of the track day drivers put the money into the car because it's a DD and they can use it off the track. It's quite another when at anytime on the track it could be sent to the scrap pile.
The reason club sports car racers are by and large older, white men is because that is who is interested and has the means. These days many if not most of the younger folks either don't have the funds or aren't interested. Or both. The people you have talked to in the Bay Area are likely the exception and not the rule.
These are both 100% accurate, in my opinion. As one of the dreaded millennial, the idea sounds cool, but not many younger people will buy, especially not entry level. When my age group thinks entry level, they think a cheap Honda civic, spec miata, chump car, etc. One that they know how to work on, that has a lot of readily available parts, and that they can either drive to the track for an HPDE, or that they can put on a cheap open trailer they rented from Uhaul and tow it with their Durango.
Also, I am not trying to be a jerk and kill the idea ... because I think it is cool, and I wish you the best of luck Greg. But I would like to add that if your demographic is entry level ... your biggest hurdle (besides the cost) will be educating to people what it is. I am not sure how it is in California, but most kids my age are too busy slamming cars to the ground and putting large stickers in on their windshields saying which camber gang they are in. And then you talk about track days to them or racing ... and they either have no idea what it is, or they can't afford it.
I am very interested to see where it goes though! Good luck!
