Understeer Issue

[Raspytooth28]

All of the cars i built have massive Understeer, what am i looking for on the steering graph? Is there any tutorials?

https://www.youtube.com/watch?v=r0eCR4NUuy0 that video (starting at around 11:10 for the slow steering graph and 14:00 for the fast steering graph, but the whole video is worth watching) explains those sort of things

We are working on a video for that.

Basically on the handling graph. The red line is neutral. The yellow line is how your car performs.

So if the yellow line turns down, it understeers. If it turns up it oversteers.

If it suddenly turns up, that is snap oversteer.

There are differences in Automation's and BeamNG's simulation. So don't expect it to be a 1 to 1 direct translation.

The yellow line is what the car is actually doing. You want it between the other 2 lines for as long as possible. Just mess with things until you get there. Try stiffening the rear suspension, reducing the rear camber, increasing the rear sway bar, lowering the ride height, etc. Even try reducing the rear tyre width, or increasing the front.

Check your weight distribution too, to get an idea of what you need to do. A rear heavy FWD car would be a real challenge to sort understeer out on, for example.

Thank you for all of your replies, I have got the car to be somewhat controllable by using your advice.

suspention deffinetly needs more customization like toe caster camber and more complex geometry adjustment, most of the cars i export to beamng show me just how messed up the suspention is because i cant adjust basic stuff like toe in and out in either BNG or automation (sure i could go into the jbeam files but i'd have to do that for EVERY car)
Wish this game had a more advanced suspention tuning mode, everything else works fine in both games.

Actually, I have a bit of an issue with this. Even though according to the graph it appears to be terminally understeering, the game often complains about the opposite, which correlates with the behavior in BeamNG.

Thanks for the suspension video you posted, it helped me setup the suspension correctly.

even beamng's cars understeer alot its usually down to the tyre's not being very grippy and yes ofc its suspention setup, ive got quite alot of grippy cars made in automation but the trick is to make the suspention setup fairly soft with grippy tyres to keep the contact patch on the road.

Thanks, i will keep this in mind when designing future vehicles.

Yep, its usually front suspention thats causing understeer and stuffing up the rear will give you oversteer its about balance.

This video should be helping more :) cheers!
