Hello

Hey, could you please help me, by telling me what do I need to use, to make all the cars' speed, and the tires' traction or stickiness a bit better? So far I know I'll have to use for k, v. But i don't know how for works. I want to make ALL the cars' max speed faster by 100, and i'd like them to be more stickier by doubling the default traction's value, and educe it's quarter.
