Edit: One thing, the LOD jumps on the rear brake duct openings on the new Ligier JS P4 are quite irritating (at least in VR). They switch from black at far away to the medium gray mesh structure at closer distance abruptly. In a certain distance following another car, this jump always happens between braking into and accelerating out of a corner, so it almost looks like an additional brake light and is quite distracting. Changing the far distance LOD color closer to the average of the near detail mesh would be an easy fix imo.

This is indeed extremely annoying & distracting alongside the MCL 720s LODs which are the only other major LOD issues related to cars AFAICS.

Reiza Team: Can you please fix the LODs of the MCL 720s (GT3/GT3 EVO) & Ligier JS2 P4 please ?

Ok it's really just not my imagination, the GT3s really changed a lot with this update. You can easily try it yourself by going for a track with the HD variant like Spa and then drive a a track like Monza where you have the LD car. It becomes really obvious how much more glued to the ground the HD variant is while the LD is the same as before.

Really appreciate all the work Reiza is putting into this and drop such great Updates out of nowhere

@Reiza: Could you maybe look into adding a tiny bit of the rear aero yaw rotation changes to LD variants too? Of course LD isn't supposed to be as stable as HD, but it think they would benefit of a bit of the recent adjustments too
Click to expand...

All cars with large rear wings have had that adjustment including their LD & oval variants; if you feel the LD variant is a little too unstable by comparison it´s indeed probably just the downforce generally you are missing so it´s worth adding another click or two of rear wing.

To provide a little more context on the change folks - basically race cars will lose some of its downforce as its yaw angle increases:

The losses tend to be higher for the rear wing than the front wing or splitter, and since the rear wing usually already produces more downforce than the frontend, that translates into the overall center of pressure shifting forward the higher the yaw angle is; because of that, if a driver is going through a fast kink that tightens into a long medium speed corner, or if he has a mid-corner rear slide he will get both a drop in overall downforce and a shift forward to the aero balance even if he manages to sustain the speed in both scenarios; the more downforce the car has, the more impactful that shift will tend to be, unless the car has design properties to counteract those effects. That is one of the reasons why slides are quicker to accelerate into a spin in high downforce cars (high performance slicks having a sharper drop-off past peak being another).

How much is actually lost with the yaw angle though? That is a trickier question and it obviously varies from car to car, but generally speaking what we found during v1.6 development was that we were being conservative with the values we were using - these remaining largely unchanged since AMS1 days which relied on a tire model that was much harder to make work at higher tire slip angles - the opposite problem from what we have in AMS2. So very early on v1.6 development we adjusted those yaw aero losses, and kept working on improving the tires´ shallow peak slip angles, but as progress continued on the latter front throughout V1.6 development and ever since, the perception became that we had over-corrected the problem and generally made rear wings too sensitive to the yaw angle of the car - that over-correction is what has been addressed on this latest update. Relatively speaking the adjustment is still "minor", and overall the yaw aero losses as of v1.6.7 are still higher than they were up until V1.5.X; but it is closer to what we understand the sweetspot to be.

Now WRT whether this "fixes the AMS2 sliding problem", that´s a very different question as to begin with it is one that can mean many completely different things the actual "sliding problem" as we perceived it to exist earlier on with which many tires could sustain, and in some cases increase cornering forces at higher slip angles had already been greatly mitigated in V1.5 and for the most part resolved with V1.6 and subsequent fine-tuning; unless you are in a vintage or bias ply tire you are very unlikely to be going faster with any car in AMS2 if you are going even slightly sideways.

If by "sliding problem" you mean high downforce cars had a tendency to oversteer mid-corner, that indeed is something that will at the very least have been improved on with the latest aero adjustment.

If by "sliding problem" you mean cars are not always on rails and they slide marginally at the limit of tire adhesion, that is a feature rather than a bug, and that will never change; anyone expecting race cars to be eternally front-limited on turn-in and traction snappy on exit because that´s what they have come to expect from driving other sims should continue driving and enjoying those other sims - it´s not what they will ever get in AMS2 because it´s not now how real tires handle.

Which isn´t to say all is perfect as is - room for improvement always exists and as we keep demonstrating update after update we are in constant pursuit to find these improvements

Renato Simioni · Aug 31, 2025 at 2:00 PM

FYI folks a couple of "silent" hotfixes were deployed over the last few hours primarily to tidy up some rough edges on the new content; a proper complementary update should follow within a couple of days now.

Siggi_Stoppschild · Aug 31, 2025 at 4:03 PM

Just drove with the Ligier LMP3 and the GT3 Gen2 Aston Martin around 24h Nordschleife 2025 and is it just me or did the driving in the game completly changed with this update to the better?
The cars feel so planted & controlable now, if you keep an eye on the tire temps they keep being predictable. I‘m really enjoying it and the track I was upset I have to pay for again is just so good.

I feel the same way. The diffrence is definitely noticeable. I did some time trial in the Aston GT3 on the 2025 Nordschleife before and after the update and for me the biggest diffrence is in Mutkurve. Previously the car was really unstable and any kind of slide was just impossible to save. The way you had to drive this corner in the old version just felt a bit awkward. But after the update it just feels so much more natural and you can pretty much just throw the car in without having to think about it too much. Instantly set a new record with the increased confidence in the rear that the new version gives you. Good job Reiza

Max Gaudreau · Aug 31, 2025 at 5:45 PM

I really like the new LMP4, but I really hope it gets its own class, same with the LMP3 from the P1 gen 2.

GearNazi · Aug 31, 2025 at 7:55 PM

With the whole aero/yaw situation and the JS P4 being such an engaging drive, I decided to run the entire LMDh line-up through Road America since I had not touched them basically for a couple builds now.(Concluded they were not for me even though I really like the more junior prototypes)

Well, it's very clear to me something changed that influences general handling/behavior quite drastically(for the better)
Granted I switched ffb to one of the latest Danielkart files...
A much more consistent aero loading through various states of yaw where previously notable dips would occur causing weird and unpredictable behavior of the rear that I perceived as unnatural but couldn't put my finger on at the time...(and erroneously blamed the tire model)
This insta-transformed entire prototype classes for me in one update.
Even the Valk that I did NOT get on with initially; probably my favourite now of the LMDh.
Like Renato said this would influence anything with a substantial rear wing to some degree at least.

Hi Renato,

Taking this opportunity, I’d like to ask a few questions that have been on my mind for a long time. Of course, these are my subjective impressions, so please take them with a grain of salt.

Overall, I’ve always had the feeling that LMDh cars are much more unpredictable to drive and far more prone to spinning in corners. Driving an LMP2 or a Cadillac DPi gives the impression of being almost glued to the road compared to LMDh. The latest Ligier feels like it runs on rails (which I don’t see as a flaw) and it’s a lot of fun to drive, even in wet conditions.

Despite having other bases, I always come back to the Thrustmaster T818, because thanks to the lack of filters I can really feel the differences when the game changes. A few months ago, when using the default+ settings, driving with damping turned off was quite exhausting due to sudden drops in force when going over curbs or during quick weight transfers in corners. After the latest update, though, it feels almost perfect—although I’m sure you’ll surprise us again with the next updates.

Overall, the car that impressed me the most this year was the Formula Vee Gen 2. The 3D model is beautifully done, the sound both inside and outside is excellent, and the handling delivers an incredible amount of information through the FFB.

Best regards

“I did it in January at Daytona, I drove the Porsche LMDh. I'm glad I checked that box, but I really did not enjoy the experience,” he told Motorsport.com at Le Mans where he raced United Autosport's ORECA-Gibson 07 in LMP2.

“And the LMDh car, pff! I felt like I'm scared. Every corner, every brake zone.

“Because the cars are heavier than LMP2, because the tyre does not have as much grip as LMP2, it's brake-by-wire so I don't have a good feeling for what is going on with the brakes.

“My only job as a bronze driver driving the LMDh is to not wreck. No one is expecting me to be as fast as all the other people, so I feel like my only job is to not wreck."

“And I would say that in an LMDh car that is a hard job, it's hard not to wreck that car."

“I watch all the Hypercar drivers spinning in qualifying [at Le Mans]. I know what that's like. Those are really good drivers, but that car is really hard to drive."

Ben Keating drove in IMSA 24 hours of Daytona in 2024 two (sic!) cars:

1) JDC-Miller MotorSports #85 LMh Porsche 963
2) United Autosports USA #2 LMP2 Oreca 07

In IMSA 24 hours of Daytona in 2022 he also drove two cars:

1) JDC-Miller MotorSports #5 Cadillac DPi-V.R
2) PR1/Mathiasen Motorsports #52 LMP2 Oreca 07

That's exactly, what Mr. Keating would say

But jokes aside, the interview about the 963 and the comments about it scaring him really are an eye opener, how much less of LMP and how much more of "GT" is in them at times. (The 963 is actually the debatably most sophisticated of the bunch aswell)

From a physics POV much like IRL the three classes are really quite similar, as alluded in the follow-up post however there is just more mass, more power, more tire in the LMDhs and that really changes the nature of the challenge especially if tires aren´t fully up to optimal range.

scotch lafaro · Aug 31, 2025 at 10:30 PM

i am just curious and its not a negative comment. Do reiza watch youtubers like badwin or game muscle for ams2 or reddit comment? Or do pro driver give you input about the handling for modern endurance cars ? I feel you really know what you are doing. Keep your great job ❤️

Ace · Aug 31, 2025 at 10:56 PM

Hey Renato, thank you for the little deep dive into this topic. It all makes sense what you describe to what I've felt with AMS2 since 1.6 and further updates. Tires felt more and more reliable, I always enjoyed AMS2 way of allowing slip angle and with all the tires updates the game allows slip but it just doesn't make you fast anymore. Honestly in some sims having cars spin out on the slightest corner exit slip feels like it's just a cop out so drifting isn't faster than clean racing. 1.6.5 already felt amazing to me. And now this out of nowhere the tweak to rear aero really was a spot on call what benefits the cars.

Maybe my intitial reaction to LD cars is just that you now feel much more difference between HD and LD. Will do some further laps in the upcoming days, play around with rear aero values and leave some impressions.

There's one strange bug that appeared since todays patch: The Corvette GT3 livery overwrites replace the Corvette and somehow also the McLaren GT3 liveries and preview images

Wow... I am impressed by how this change is affecting the cars. You definitely have made a huge step in the right direction with this, and IMO, as others said, they feel more predictable and aligned with what front/rear wing adjustment we do on the setups.

After testing FUltimateGen2 and GT3s at Suzuka, I can definitely notice this improvement. I have understeer when I expect it and not as before, where it could be corrected a bit pushing with the throttle to slide a bit or lifting. Now, I have found moments when it is definitely too late to correct that understeer when at the limit, and that terminal oversteer others complain about seems to be gone.

Awesome work!

100% agree, not only an excellent addition to AMS2, but up there with the top cars in any sim.

The vee is easy to drive but also easy to mess things up and lose time or spin out when you start to push, this is a car that will teach you more in an hour of driving than 50 hours in a GT3. Especially if you are using a H shifter.
