Post Update 1.49 Suspension Compression Issues - Possible Glitch?

[WolfpackS2k]

Since the latest physics update, several of my cars have become undriveable when encountering track areas where the suspension encounters extreme suspension compression.

When this happened in the past I was usually to blame by lowering a car too much, using wheels too wide, a combination of the two, etc, leading to clearance issues between the tires and car body. However, since the latest update this is happening to many of my 100% stock vehicles. I haven't tried out all of my stock vehicles (who has time for that?) but the biggest offenders I've found so far are the E36 M3 and 964 911 RS. There are spots on many tracks with problems, but the easiest ones to identify occur on the Nordschleife. Specifically the downhill dip after Flugplatz, as well as at bottom of Fuchsrohre (Foxhole) and especially the drop at Pflanzgarten, also to a lesser degree the bottom of hill at Tiergarten. This is extra annoying given Nordschleife is my favorite track.

The steering wheel suddenly turns over 90° and will crash the car.

To fix this issue on my 964 I continually tried raising the ride height with full custom suspension. Minimum height for that car is 75 mm. BEFORE the update my car was perfectly happy at 105 mm. But now, that doesn't work. I tried raising the height, 5mm at a time, to get rid of the issue. No luck. Went up to 125 mm and at that point the height started to negatively affect handling in all aspects.

Again, this is happening to stock vehicles using sport tires (SH and SS, haven't tried SM but shouldn't matter). Stock wheel sizes as well. Anyone else experiencing this? Please help.

Try increasing the natural frequency and the compression damping. The force of the springs is proportional to the displacement, while the force of the damper is proportional to the velocity of the displacement. So when you increase the damper compression setting you absorb more of the shock from sudden compressions.

I mentioned the exactly same thing in the thread related to said update (1:49), exactly the same problem and exactly the same spot at the Nordschleife.

The car I was tes driving at Nordschleife was the Aston Martin V8 Vantage. The solution I found for it was setting the natural frequency to the max.

It has been working for many stock cars I drove there that display that problem.

In addition to this I always set the dampers (compression and expansion) to be stiffer (not max out though) and try to not set the car too low. At least not as low as before the 1:49 update.

As I don't seek tunning my cars to max performance, for I rather try to "just" improve them a reasonable bit, the height adjustable suspension does the trick for me. I'm sure the fully customizable suspension will get you even better results.

Edit: corrected typos

Thanks for reply. I feel like setting the suspension to be extremely stiff is a poor solution, especially given that the problem occurs mostly on tracks where you DON'T want a stiff suspension, lol.

Glad you found a "fix" but that's not really a fix. Stock vehicles should not behave that way, and given that they were not before update 1.49 that would indicate that PD ****ed up here. To which I ponder, does anyone know if PD is aware of this? They have to!

I'm not sure if it's the combo of cars and tracks this week but 2 of the weekly races so far have been awful.

The Daytona race, I used a old Mustang, everything I hit the banking it chucked my to the infield, the race was unplayable... I recorded it so if someone could advise how to get it from PS5 to here I'll share.

The Lambo special event was just a trail of oversteer the second the brake was touched and then low speed unrealistic understeer.

Will also post in the weekly race thread if this is the wrong place.

I don't know it this issue is related somehow but i have found some of my road cars (older ones) cannot have race tyres installed or the warning triangle of PP doom appears, I change any and all settings possible with race tyres and its a no-go situation until i change them to sports tyres. Does anyone have same experience?

Try mounting a 'lesser' tire. I had nearly always the same issue with the stock 992 at foxhole and sometimes at the two other spots you mentioned when Racing Softs were mounted. I believe it's a grip issue in stead of a suspension issue. My car just shot away in a direction and there was nothing I could do about it. Racing Hard made it better and Sport Soft 'fixed' it for me.

I have this with one of the Evos on stock susp and SH tyres, I cant remember which,the E36 on race susp is another'funny'one since the update.Some people give it the learn to tune speach but im not convinced.If it was one person having the issue I would get it but its clearly not.
There are other cars that arent great for me since update 1.50,my engine swsp Yaris is one.That used to corner on rails on Tokyo and Grand Valley but not anymore.Ive got it to a reasonable level by messing with ride height and natural frequency settings but nothing like before.
It is what it is I guess,fingers crossed for the update. 🫱

@Daxus Adding a lesser tyre might make the problem bettet but is not really the correct fix though is it?
Ive never raced but I wouldnt expect touring car drivers to ask for harder tyres because they have handling or suspension problems.Maybe they would,I dont know.
I get where your coming from but for me this was not an issue before the last update.Hopefulky PD can sort it.

Maybe it wasn't clear but I never mentioned race tires. I said Sport Hard & Sport Soft tires.

And I mean, how do we report these issues to PD?
