erm i got quite alot id like to c changed:
-Tyres: they need to be able to use all 3 types(dry, intermediate and wet), its safer, cos if a team only brought dry and inter, and rain falls, its unsafe. The slicks must come back IMO
-The engine must NOT be used for an entire weekend, its F1 not Le Mans damnit!
who cares its cheaper this way, its F1, its suposed to be the pinnacle of SPEED, not honda-like reliability!
-Ride height: the cars are now limited to a couple of cm's above the ground, if u look u'll c the Le Mans cars are much lower to the ground. Also they shud b able to use ground effect(venturi tunnels and stuff like that), not the ridiculous wooden plank under the car
-Minimum weight: as long as the car passes its crash tests, they can save as much weight as they want IMO
-All the rules for where u can and cannot put wings should be abandoned, so there will be better use of the available room on the car.
The last 3 suggestion wont only make the cars faster, it also stimulates more R&D, more innovation in F1. at this point the teams are only trying to improve their cars by iny tiny changes within the rules, while in the early days, there was soooooo much more experimenting, and alot of revolutionary inventions were made in F1. Today's rules make that impossible
