Commands
/offset [Front/Back] [Value]

Examples

/offset front 1.6 - This would set the front wheels 1.6 units out from the center of the car
/offset back 1.6 - This would set the back wheels 1.6 units out from the center of the car

/camber front 0.9 - This would set the front wheels 0.9 units of negative camber
/camber back 0.9 - This would set the back wheels 0.9 units of negative camber

/camber front -0.9 - This would set the front wheels 0.9 units of positive camber
/camber back -0.9 - This would set the back wheels 0.9 units of positive camber

This script will sync the offset and camber values of the car to all players currently connected to the server. New Players who join will not see the changes unless the changes are re-applied when they're connected. 
This could simply be resolved with storing the vehicle data but no one atm can be bother implementing it.
