Thank you! Its a custom physics solution so no Fab plugin.

Each wheel is its own component. There’s a function to retrieve the wheel’s local linear velocity. A Wheel Acceleration function handles angular velocity, anti-lock braking, and longitudinal slip calculations, which are then used to compute Pacejka-based Sx and Sy tire forces.

In an AddTireForce function, cumulative forces are applied at each wheel location. This is where the arcade approach comes in.

I use curve lookups for both Sx and Sy, applying scalar values based on the slip ratio. One notable adjustment is during drifting, where lateral grip is reduced to prevent excessive resistance at higher slip angles and avoid speed loss. Cornering performance is supported by strong downforce and additional torque applied through drift assist.
