yeha but in the game if i change to 5th gear the car can move in real life the car cant move in that gear.
you see if i script it that way:

if(gear == 1)
{
motor2 = 10
}
....
if(gear ==5)
{
motor2 = 50
}

i can start the engine in 5th gear and the car will go even beter...
its not like gear ratio you just get the motor more power...
i know all about car's i know how real gearbox and drivetrain work's but i cant manange that into the physics engine because the motor function just add amount of power.
i think that i will need to do a constant motor power and to build gear system that bypass the motor...
but i need to do more thinking....

but what about the other problem????
the rear wheels are messed up!!


BTW: Sorry for my english.
