SpecE30 is awesome and has good staying power. The Hp rule is interesting, but not unnecessary maybe. Just like your racecar, maintenance is important for durability.
Classes are competitors in a marketplace with a somewhat defined number of customers. To be a healthy market, you don’t stack your store with the exact same goods but a different logo and paint color on top of the market leader. The goal with SpecE46 isn’t to move people to a different class - AT ALL, and there is no pride of creation or ownership. The goal is to have a good place for people who might want something different than what an awesome entry-level class is - not a different color or flavor.
A lot of my friends and customers have been in various other classes and they are great until someone starts spending big money and thinking outside the very large box that was defined in the rules - if there was one. For guys that want to go faster, have more technically interesting cars, like turning a knob or two, but didn’t plan to get a second mortgage to finance it, there should be a proper, stable home. If there isn’t one for them in NASA, or the larger racing community, golfing or boating will always have one, and I have seen plenty of people go that route. The goal isn’t moving racers to OUR class, it is providing YOU (well them - not you SpecE30 guys that love what you do) a place for this type of racer, which doesn’t already exist, that can be a home for lots of years, just like SE30 is a good solid home for racers that like that class.
