I would:
- 3L V8 with no restrictions and/or 3L V10 with just the air intake reastrictor
- Slick tyres, with the rear being like 2 as wide as front
- Yes for tyre changes
- refuelling to a certain extent (limit fuel used per team)
- No for traction control (but maybe in rain)
- No for launch control
- No team orders because then you can't really race for yourself and have fun
I think it would be a good idea to bring the rear wing and front wing back to when car were able to overtake eachother. Like the rear should be moved back and the front should be lowered 2 the ground.
