Regarding #3: While big brakes are better, the brakes in F1 are so incredible already that idk if more weight would be worth more braking power. You also have to take into consideration the brakes must warm enough to work correctly. I’m no engineer or brake expert, but that would be my thoughts

Red Bull basically already has Torro Rosso. They aren’t allowed to share data and what not, but similar

Not to mention tires blowing up are dangerous for the following drivers. Could lead to debris hitting drivers or clogging up air intake, brake cooling intakes, aero pieces, etc. Plus, 2psi is a bigger difference than .05... It is a bigger difference in lap time as well as how long the tires last before they need to…

Also important to remember that the dimensions of the cars will be completely different as well. So while they do look a little ridiculous on the test mules, they should look appropriate on the 2017 spec cars
