Whats the best colider to use for my race track?

i’m pretty new to unity and i’m having a few problems with mesh coliders. My track has a lot of curves and elevation and i’m not sure what the best colider to use is.


mesh collider with convex unticked.

Iv tried that but still get errors with the car floating and bouncing

Also when I turn it off it slows my frame rate from >1000fps to 2fps cause it doesn’t reduce reduce the mesh triangles
