1. Give the teams a higher share of the income from F1, particularly the lower order teams.
2. Allow greater freedom on the number of cylinders and how they're laid out to form the engine. Allow turbine or mechanical supercharging and rotary engines too.
3. Prevent exhaust blowing of the rear of the car for aero purposes. Exhausts must terminate at least 100mm vertically and 250mm horizontally from any bodywork. The exhausts must terminate with their axis pointing up at 15deg.
4. The FIA measures out the fuel for the race. Each team gets e.g. 100kg (or whatever we want initially) and they decide how they use it. No limit on fuel flow but once it's gone, it's gone. The teams choose their fuel strategy within that limit.
5. One tyre construction for the season. It'll be too hard for some circuits and too soft for others. Get over it guys and engineer your race accordingly. Increase the number of sets available for each driver. Inters and wets to remain as current rules.
6a. Free up the first 300mm of the floor below the sidepods. Allow a much greater maximum radius on the leading edge. This will allow the underside to make more of the overall downforce.
6b. Allow a large diffuser at the rear of the floor behind the sidepods but not in the central 300mm. This central 300mm section will be a mandated crash structure.
7. Limit front and rear wings to a main plane and a flap. Allow the teams to run them at whatever height they wish.
8. Allow active suspension systems. The current plank and stepped underside to remain.
9. No TC and no ABS/ESP systems. Anyone found trying to implement one of these will be thrown out of the season and any prize/"attendance" money withheld.
10. Allow each team 5 days of testing during the season on top of the current pre-season test sessions. They choose when they go testing. Must be at an approved circuit, not a team owned circuit. May be taken on the Monday after a GP at the GP circuit (this would help poorer teams as they wouldn't have to transport everything to another circuit just to test).
I had thought about suggesting success ballast as used in some championships. It's a bit artificial but no worse than e.g. DRS and it has the benefit of bunching up the drivers as the season goes on. No more run away seasons.
