v3.0 is now out with some major improvements and changes!

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 with only minor differences from Unity’s inbuilt WheelCollider – familiar and easily swappable.
• Fully customizable via custom inspector. Adjust spring, damper, friction curves, geometry, etc.
• Adjustable camber, caster and rim offset.
• Pacejka friction model with support for different surfaces.
• Friction preset system.
• Adjustable at runtime.
• Adjustable ground detection resolution (mostly between 5 and 25 rays per wheel).
• Can handle wheel visuals by itself (rotation and position).
• Suitable for different kinds of vehicles: cars, trucks, motorcycles, tanks, etc.
• C# (OOP) with documentation and API reference.
• Source code included.
