I voted yes because it is a great idea in my eyes
Of course you have to put a limit to every car, a value at which it just starts spinning and sliding out if you put too much or too little downforce, so people don't just make 500km/h builds or cars that have 0 loss of traction
If these values are adjusted correctly, it could bring more flexibility to people who actually care, and those who don't can just use the spoilers as is, just for visuals
I mean, dyno tuning is coming too, so why not downforce too?
