How do I make cars not fly up into the air when turning or accelerating?

Spoilers just act like wings, pulling my vehicles up into the air, unless I add hinges to turn them downwards more or tilt them sideways, but that makes my wheels clip into the ground causing other issues.

post the vehicle, spoilers should create downforce while right side up without requiring being angled (i use them a lot on race cars which often are really fast and need to turn sharply, everytime i have used them they have made my vehicle stick more to the ground)

I've tried a lot of different vehicles. Whenever I turn any of them, if they have suspension they lean, causing spoilers to become wings that lift the vehicle. If I don't have suspension, the vehicle just flips on its own.

as i said, post the vehicle. There is not much i can tell you about why it happens when i haven't seen your vehicle and i know it doesn't happen most of the time

I don't save any vehicles that don't work, but if you try the "Jet Car" template vehicle, you'll see what I mean. It has good aerodynamics, but it can't turn without flipping. Same with most Workshop vehicles.
Here's a vehicle that I got to not flip, but the downforce had to be so strong, the wheels sink into the ground causing it to explode when going over any sort of bump or hill.

The problem with jet car is that it only has downforce on the back, which makes the front have less grip. When convined with how thin it is and that it has weight higher than necessary lifting the center of mass you get a vehicle that easily drifts and flips over on turns. Moving blocks closer to the ground, moving the front wheels a bit outwards to make it wider, moving the back spoilers a bit closer to the middle and adding 2 spoilers to the front completely fixed both problem

As for the vehicle you posted, i haven't been able to make it flip even after removing both all spoilers and suspension. The wheels sinking into the ground is caused mostly by the mass though, you can see this by looking the small difference there is between not moving and moving at high speeds (spoilers create very little downforce while not moving)

you don't need downforce if your powered by jets
