How do you know you were locking the real axle?

 

You did a much more complicated version of my proposed test above, but I think the same conclusion is drawn.

 

I do not know how valid my testing was, but I did some testing in TT using the default setup of the Aston GT3 @ Spa 2022. I turned of TC and pushed to do the quickest lap I can make. I also recorded data to see how much slip angle I reached without feeling like I lost the car. I did roughly 5 laps and I noticed that my peak slip angle was just under 6 degrees. Now I’m no expert on tyre dynamics, but my research suggests that the amount of slip I got is a realistic amount. If there’s any info you want or some things I can change to make the testing more reliable then please tell me. I want to make AMS2 as good as it can be and I think independent testing like this can be a way of double checking that everything is reasonable

 

I will check that. I don't use Default+ so not much effort making it work right. Before I start doing FullFFB, I used Default+ and I have it much lower (10-20?), if I remember correctly!

 

IMO the rear of the car is completely predictable and behaves as it should. I've never lost near without knowing what caused it.

The front end in other hand.. It has all the grip in the world and i can just steer the front however i wish regardless of inertia. Then i just keep the car in very controllable and unrealistic front end slide thru the entire corner. This enables very unrealistic rotation so overshooting the corner is impossible.

It feels very rewarding tbh but completely wrong. Atleast i can feed my ego with laptimes which would be alien level in ACC.

This applies mostly to the gt cars but in some extend to all classes, expect some classic low df formula cars.
They feel very nice with a loose rear and front end on rails.
The front maybe has unrealistic amount of grip even in these classes and you can really dance the car on the nose.


Overall i think AMS2 physics are excellent and ahead of many competitors. Only those issues around rotation and front end grip’s disrespect to laws of inertia botches the ensemble.

If Reiza can fix this, i think AMS2 become all time greatest sim to the date.
