Problem with Wheel Colliders: Jitter and unstable!

Hello everyone,

I am currently working on a VR Biking game and need some help with the wheel colliders. Since simulating bike physics is no easy task I opted for just making a car with 4 invisible wheels and using my bike model. I had it working but decided to try to make a more realistic feeling bike, which failed. When I tried to get back to the working "Car style" some issues started to appear:

• Extreme Jitter, horrible for VR!

• Weird behaviour when turning

I tried everything in my power to fix this, including:

• Disabling VR Mode

• Disabling any Camera or Movement scripts attached

• Lowering / Raising the gravity in the Physics Settings

• Modifying the Wheel Collider values

• Changing the Center of Mass to any position (towards the front / back, move it up / down)

• Entirely deleting Unity with all the settings files and reinstalling

NOTHING Worked! So I decided to create an entirely new Project and simply follow Unity's standard Wheel Collider tutorial. I recreated the given instuctions step for step exactly like shown, but when I hit play and drive around the random jittering still occurs, even on a completely flat plane! In my confusion and rage I made this video simply showing all the settings and the weird effect: https://youtu.be/ujn5TJ3Mv4g

What is going on here, does anybody know? I'm sure it's just that I forgot about one super simple thing or something stupid like always, just need a nudge in the right direction :)
