Track mesh collision issues.

Hello everyone. I am a game design student working on my next biggest project. I am new to the forums but I am pretty familiar with unity. I am a 3d artist at heart, but have delved into about everything at some point. Currently I am working on a sprint car game. I have a car setup and physics system set up pretty close to how I want them, but the problem is that my car seems to collide with every line in the track mesh. The track does fine when it is flat, but when I add the track tilt to make it more like a real sprint car track the car collides with even the smoothest surfaces I can come up with. At this point I am stumped. Here is a small snippet of what I am working with…this track is pretty smooth but you can still feel and see the problem. Any help would be awesome. Thanks everyone.

Nobody knows? I’ve been working on it alot recently…I’ve looked at every car tutorial I can find and still cant find any good answers…it seems nobody really uses a track that turns sharply or has much curvature to the track…Starting to think that unity or this wheel collider car setup isnt the best to use for a serious simulator. I’ve turbosmoothed, meshsmoothed, anything you can think of to make a smooth track, but it seems it just cant understand how to collide with the track mesh correctly. If anyone has had any similar issues get with me so we can work something out. Thanks.
