Bug Reports - Automobilista 2 (Read the Opening Post)

I've already posted about this more in depth here, however I've decided to report this as a bug because I think it's a fundamental flaw with the setup of any/all cars in the game with a clutch-type LSD. I believe this is a large factor in the proposed "slidey-ness" of AMS2 as a whole.

The problem:
The ramp angles are set backwards on every car in which I am able to see and edit the values in the setup screen. I can only assume it's the same for all the others where these values are hidden and unable to be edited. (GT3 cars spring to mind.)

For example with the default setup for the Porsche 963 LMDH, the power ramp is set to 65° and the coast ramp is set to 40°
The problem being a shallower ramp angle (closer to 0°) actually provides MORE locking force than a steeper angle (closer to 90°).
These values should be opposite.
Ex. Power 40° and Coast 65°.

Put plainly:
The lower the number on the setup screen, the higher/more aggressive the clamping force inside the diff.

This means under acceleration the diff is allowing one wheel to slip and spin faster than the other due to the steep power ramp angle, especially under lateral load for instance when getting on the throttle at the apex of a corner. In this instance it should be clamping the two halves of the rear axle together to provide better traction.
And under braking the shallow coast ramp is actually causing the diff to lock undesirably causing a snappy sensation when trail braking or braking at all when the car is under lateral load.

On a real life racing car you would essentially never find the power ramp being steeper than the coast ramp. You may set the power ramp to a slightly steeper angle to prevent excessive traction loss when it's wet, or if the track is old and has a bad surface; but you'd still never have the coast ramp shallower than the power. It makes no sense, hence why I believe this has been set this way in error.

To test this yourself, find a car with a clutch-type LSD that you can actually change the ramp angles of.
Drive it on the default setup for a few laps to get a feeling for how it drives.
Go back to the garage and swap the two values over so the power ramp is shallower and the coast is steeper.
Drive a few more laps and feel how much more stable the car is on the throttle, how you get a slight push of understeer when getting on throttle mid-corner and how it rotates nicer off throttle, especially when trail braking.

 

• Locking Action (Generic Explanation):
  Steeper ramp angles (e.g., 30 degrees) result in more aggressive locking, meaning the differential engages more quickly and transfers more torque to the wheel with better traction. Shallower angles (e.g., 60 degrees) lead to less locking, allowing for more independent wheel rotation, which can be desirable in certain situations.

Differential Tuning Discussion

It's not a bug, just an issue of terminology.

But you are correct that values never or unlikely to be used in real life are possible in the game.
