Wheel Controller 3D is a complete alternative to the Unity's inbuilt wheel collider. It allows for more realistic vehicle behavior, complete customization and 3D ground detection. No more "stick" wheels!

Features:
• Wheel has width and length, not only a single point in the middle.
• API similar to Unity's WheelCollider + extra features.
• Fully customizable via custom inspector.
• Camber and caster angles.
• Pacejka friction model with support for different surfaces with ability to change during runtime.
• Adjustable ground detection resolution.
• Handles wheel visuals by itself (rotation, position).
• C# (OOP) with documentation and API reference.
• Works on mobile devices.
