Yeah, I understand you don't need to tech MOTORS with a claim rule. However I would never want to be in a claimer division. Too many headaches with that deal. Lose your $5000 motor for $1050 or $100 and someone else's junk? No thanks. I don't think that would be very popular as a startup now. So the rich guy can have two cars. One with a super motor, ths other with junk. Get too fast and he can slow you down by robbing you, giving you junk then using your good motor when his gets claimed (or just ponying up for another high dollar motor he can afford to lose). Too many games can be played with that deal. Just put out rules and tech 'em.
