I've been thinking about changing a few rules of this championship (after examining how extremely limiting this system is). *Raising Engineering Time to 72 months *Upping Production Units to 150 *Increasing maximum price to $25,000 (with a mandatory 20% margin after $20K) *Allowing boxers only for rear-engined applications I think this might allow a few more cars into the championship, although I'm still not sure if it'll work all that well.
