Its simple, build a f1 car,

Regulations;
Must have a halo
Cant have better launch than 2.3 seconds (for realism)
Cant have downforce exceeding 960 kg in the rear and 910 in the front (if this rule is not obeyed your car will get tuned to stay in the limitation)
Max fuel allowed is 20 gallons (the car should atleast do 3 laps with no additional fuel, this would also get your car tuned back to normal)
Cant have a top speed over 357 kmh
(Trust me, it will be bad for your handling)
No rudders
Cant weight over 988 kilos
Must have a 45 degrees steering angle
No fan cars
Hp will be set low to have accurate accel
NO REPLICAS
No real sponsors (fictional only)

I know it has a lot of rules but it should be competitive ;u have 4 days to make ur car.
