so what are the changes? new sounds?

 

[AadHofman]

If it turns out that the rear tires overheat in twistier tracks too quickly, I will introduce a harder compound as an option.

 

[Leonardo Ratafiá]

new engine sounds then.
you should do more clear change and detailed logs. thanks
cheers

 

[AadHofman]

...nevermind...

 

[AadHofman]

Ok, I can confirm there's a temperature issue with the current compound, and a fix is needed. Thanks Robin_NL for pointing it out!

Why is there another archive file in the folder?

 

[AadHofman]

Damn, I thought I had deleted it. It is of no use. Reuploading shortly.

Hmmm, I think the tires went a bit too slippy in the lastest update...

I took a look at the car. Strut for semi-trailing arm is a bit questionable given that DWB generally does a good job in reproducing the camber curves, but I trust the suspsim. However I'm not sure what exactly that front lower arm is. While AC does have issues with anti-geometry and this is a fix for that I presume, you will be screwing up the toe and camber geometry through travel. Perhaps not the most ideal solution. Do you really get the same curves in AC as in the suspsim? Is it an oversight?

 

[AadHofman]

Do you mean the front lower arm of the rear suspension?

In any case, you can say it is an oversight, since I wholly trusted Suspension Analyzer on this (camber gains, caster gains and all). I haven't checked any telemetry in the game, but it drives beatifully, so I have assumed it works as intented. Feel free to analyze it better.

You must adjust all suspensions for AC to correct the anti-forces due to the buggy suspension forces in the public branch. Not to mention such a wide arm geometry will most likely mess up the steering geometry if you modify it for a longer lower control arm for example, and will produce an incorrect steering feel in the context of the simulation. It'll only work for this one specific use, but if you were to change the parameters at all, it will fall apart and need a redesign, is what I'd guess. If we had suspension stresses and bushings that moved, it'd be more apparent.
