Steering issue, doesnt go straight

Question

I have a small problem where the car will slightly go left or right (mostly right) when im only pressing the forward key and i can also see it change in the telemetry window, what could be the problem?

Answer 1

Possible causes:

• Center of mass not centered or not assigned in the vehicle controller. Best practice is to create a child gameobject at the proper CoM position and reference it from the vehicle controller's Center Of Mass property.
• Non-symmetric or malformed inertia tensor. Best practice is to configure the Parametric inertia mode in the vehicle controller.
• Wheel positions not symmetric. This includes the Offset value in the VPWheelCollider component.
• Suspension properties not symmetric: distance, anchor, spring, damper.
• Wheel properties not symmetric: radius, mass.
• Aerodynamic components or external forces not being centered or applied asymmetrically.
• Left-right wheels driving on different ground materials.
• Ground mesh not perfectly flat and uniform.
