I like the old school, full contact racing and drivers with attitude. The series would have 30 races per championship season, with an extra 4 non-championship races.
No chase. Whoever scores the most points wins. I'm not going to get into a whole new point system, so we just go back to the old one that rewarded good finishes and allowed drivers a better chance to recover from bad outings. Once the championship is decided, everyones points are set to zero, and the remaining races are run under a free for all format, with the winner getting half the purse. Bring your old cars, and settle some scores while going for the win.
All 30 of these races count toward a drivers career totals.
The other 4 races will be spread throughout the championship season. Exhibition races staged at new tracks in new markets, and could involve playing out car and rule changes.
Stop sanctioning drivers for what they say, even to the media. They are all adults, so let the teams and sponsors handle it.
No more splitter or spoiler. Having aero so important to your speed means you have to avoid contact, or even rubbing. Fix the side pipe tire shredder, and let them rub and bang for the win. Move to a smaller engine, and lose the restrictor plate. Slow the cars down, and use a softer tire. Also, go to a wider rear tire.
Limit the momentum racing by altering many of the 1.5 mile cookie cutters. Force them to brake hard and muscle the damn car around the track.
Go to a digital template, with quick laser measurements for inspection. A rolling assembly could measure any car in 60 seconds to be sure it's within the digital templates provided to every team. This one template fits all has killed the charm of the sport where you could watch YOUR car race on Sunday.
Street car bodies. With digital templates, each manufacturer could bring multiple models whose sections are center-line adjusted to fit the safety frame. nascar used to make fine adjustments to cars that had a big aero advantage. Go back to that formula.
I know it's crazy, but I want stock looking cars being DRIVEN hard each week. Where are the days when a torn up car could still compete? I don't want to watch gentleman racing, I want competition with attitude.
Forgot the master plan. Once new markets have been developed, start a Cup series west. East and West would race the season on tracks in their markets. At the end of the regular season, after East and West champions have been crowned, the top 10 teams from each series would have a 2 race shootout at 1 East track and 1 West track.
