Seperating front and rear tires on Wheeled Vehicles

I got the idea to seperate the front tires and springs from the rear tires and springs. I now have a buggy with small front tires and large rear tires both front and rear having diffrent settings to achive more realistic handling.

thoughts ?


datablock WheeledVehicleTire(DefaultCarTireRear)
{
shapeFile = "~/data/shapes/car/tire2.dts";
friction = 2.0;
lateralForce = 7000;
lateralDamping = 50;
lateralRelaxation = 1;
longitudinalForce = 7000;
longitudinalDamping = 50;
longitudinalRelaxation = 1;
};


datablock WheeledVehicleTire(DefaultCarTireFront)
{

shapeFile = "~/data/shapes/buggy/wheel.dts";
friction = 2.0;
lateralForce = 8000;
lateralDamping = 200;
lateralRelaxation = 1;
longitudinalForce = 8000;
longitudinalDamping = 2000;
longitudinalRelaxation = 1;
};


datablock WheeledVehicleSpring(DefaultCarSpringFront)
{
length = 0.85; // Suspension travel
force = 3000; // Spring force
damping = 1000; // Spring damping
antiSwayForce = 3; // Lateral anti-sway force
};

datablock WheeledVehicleSpring(DefaultCarSpringRear)
{
length = 0.85; // Suspension travel
force = 3000; // Spring force
damping = 2800; // Spring damping
antiSwayForce = 3; // Lateral anti-sway force



This is how I add the tires to the Vehicle


function WheeledVehicleData::onAdd(%this,%obj)
{

for (%i = 2 ; %i >= 0; %i--) {
%obj.setWheelTire(%i,DefaultCarTireFront);
%obj.setWheelSpring(%i,DefaultCarSpringFront);
}// End Front tire for loop

for (%i = 3 ; %i >= 2; %i--) {
%obj.setWheelTire(%i,DefaultCarTireRear);
%obj.setWheelSpring(%i,DefaultCarSpringRear);
} //end Rear tire For loop

} // End Function

};
