Here are some great Unity car physics repositories on GitHub, ranging from simple to realistic:

Uses a simplified TorkWheel for easy grip and friction tuning. 🛠️ Key Technical Concepts

// apply torque to rear wheels (RWD example) wheelColliders[2].motorTorque = torque; wheelColliders[3].motorTorque = torque; [RequireComponent(typeof(Rigidbody))] public class VehicleController : MonoBehaviour

Techniques for Realistic Car Physics

The "perfect" car physics setup depends on your game's needs. If you want a quick prototype, a WheelCollider-based GitHub repo is fine. For a professional sim, look for Raycast-based systems utilizing Pacejka friction.
