FGear Vehicle Physics (v1.4)

Somebody here integrated any kind of burnout system? Can somebody share the code or give any tips of how it should be?

I started with some idea that is something but far to be as good as needed:

	  if ( speedUI < 25.0f && mWheelTorque > 0.0f && mAccel > 0.0f ) 
	   { 
	   // START VALUE   || 0 Mass Wheel
	   mMass = FMath::Lerp(0.0f, 
	   
	   // DESIRED VALUE || From 0 to default car Mass Wheel
	   mMassDefault, 
	   
	   // SPEED VALUE   ||  The lerp speed sets the final value
	   FMath::Clamp( speedUI * 0.04f , 0.01f, 0.99f) ); 
	   }
	   
	  else  { mMass = FMath::Lerp(mMass, mMassDefault, 0.01f); } 

Basically when car speed is less than 25km/h, the mass goes from 0 to default based on that speed. It makes that on car stop and accel or when doing 180ยบ turns, the wheels on that speed range got lot of spin giving a good feel but have also some cons too.

So before develop or try other ideas, wonder if somebody already did it and what values or how it was achieved.
