wheelcollider friction and braketarque confused

hi~ all
i am reading doc about wheelcollider
now i have some question:
what is the difference between forwardfriction and braketarque:
is asymptoteValue/extremumValue of forwardfriction the max value of braketarque??
for example when the car is not slip
braketarque = 100
extremumValuestiffness = 1000
what is the real force added to my car
and what about
braketarque = 1000
extremumValue
stiffness = 100
or should i caculate braketarque by forwardfriction
some one plz help

ah~~~ some one help~~

Hi:)
To be honest, I recommend you to use the standard and plays with slip friction.
Everyone uses standard in most cases, and handles the wheelsColliders via script if necessary.
Checks on YouTube there are many tutorials on vehicles.
cheers.

Formulas for wheels colliders i don´t know.

well
thanks pauloaguiar
i got some real bad problem with YouTube
u may not know
when every pathetic chink(yes i call myself chink) type in “www.youtube.com”(as well as facebook) within ther explorer,the magic happens:
404 not found
the truth is their god damn gov has create another GreatWall called GFW(great fire wall) which make every chink their slave.
fuck chinese gov!!!
fuck GFW!!!
fuckfangbinxing(father of GFW)!!!
well, i may thank these busters cause i can still visit unity3d.com, (but fuck them again!!!)
and
thank you all the same

i mean no offence
pauloaguiar
just these busters made me angry
i just want my god given right back
apologize for my words above(it is hard to keep calm)
thanks again

My understanding is the extremium slip, etc. are all about the friction between the wheel and the ground. Braketorque and Motortorque control the rotation of the wheel. So if you increased braketorque very high but had the friction very low, the wheel would stop, but it would be like sliding on ice. If you had high friction but low braketorque, it would be like you were coasting.

No problem:)
