Brake strength

[cotharyus]

Ok - after some fooling around with break frictions on a couple of cars and making some notes:

The G4's brakes are about right. The problem I seem to have with the G4 is that any amount of braking seems to cause the (already very loose) rear end to step right around. The cure? It's downforce folks. I don't know who is in charge of specs on this car, and exactly what all the numbers mean, but when I change the -0.5 on the lift-coeffecient to 0.9 on the rear wing, the whole works gets a lot better. Part of my wondering about this number is looking at the same number on the AX2 (defidently not enough brakes on here) it is an even -2.

On that note, I upped the brake friction on the AX2 to 0.92 and it was much better. Still not stopping the way I expect a _race_ car to stop, but better.

So - who comes up with these values, and where do the values come from? How open are we to changing some of these values until they are reasonable? I realize that based on what I've read about some of the cars, that downforce might just be masking some problems in suspension geometery, but we have to start somewhere.

Also on a side note, what, exactly, is the AX2 supposed to be? It certainly seems like it could stand some taller gears, as it tops out very quickly.
