So, it turns out that for $1000 bucks, I can add aftermarket traction control to the racecar that is designed to work specifically with my engine management system (works based on driveshaft speed, and learns the acceleration rate/adapts to changing conditions).
I'm wondering if I should go that path despite the price, since that sort of system would have prevented the exact type of very expensive wreck that I had at my last race - it will pull power out if you start to spin the tires coming out of an apex or over a pavement transition. Thinking of it as an insurance policy, given how fragile the car is now, and the amount of money I have sunk into it.
