I'm a rookie who doesn't really understand classing, PAX, PIP, etc., and frankly doesn't really care. I compete against myself and enjoy as many cars on the track as possible, when I TA. But I'm in favour of access and participation so, as I understand this, the 13 class system may be best for that. I'd be happy with a really simple to understand 3-class Extreme for everybody...perhaps based only the horsepower to weight PIP. I know there's tons of other technical things to consider but I'm not into it and never will be. Just want to mash my pedal in a safe, sporting and fun way. Thanks for engaging in the discussion, appreciate everything the volunteers do. Cheers.
