It just so happens the 787B is available now (at an inflated price of 3,300,000 Cr.), and the R92CP is due next in Hagerty's rotation (down to the launch price of 2,000,000 Cr.). The Jag will be disappearing momentarily (and likely will be gone by the time you see this), while the Sauber is also available now. Unless you already have the 962, forget about it - it's not due again until December, so if it's not the upcoming special pick, you won't be able to get it.

Don't worry mate, I got all the cars already (two each in fact - 1 billion credits and counting lol). I just prefer to test using loaner cars to avoid putting too many miles on my garage cars and having to pay for maintenance

You don't get rich spending your own money, after all.

My fastest FP lap is a 3:18.1xx in an aero tuned Hyundai. I can get the R92CP around in a mid 18, but that was with only some very perfunctory aero tuning, so I suspect 17s are possible. The 787B is also good for a high 18.

With some aero tuning on the Hyundai, I've also managed to handily beat my previous fastest FP lap set with a Gr.C car -- 3:23.172 now, down from 3:24.814 (set with the XJR-9). I think I may have been the beneficiary of a magic session on that one, though. It came after a 25-point adjustment to the front downforce, and resulted in lap time improvements that seemed unreasonably large for such a small change.

What step size do you all use for downforce tuning, btw? I started with steps of 100, but this dramatic change from a 25-point step has me wondering if I should be using smaller ones.

I feel like I might need to work on a set of aero tunes for different weather conditions. My expectation is that, like last week's Manu, we'll only have a dry track for qualifying and spent the race in the rain. My guess is that I'm going to need stronger downforce in the rain to get the most out of the car.

Does anybody have any tips for tuning for weather? I'll need to use either custom races or multiplayer lobby practice to control the weather. Is there a way to get the optimal lap time out of either of those after a race/session like you get from time trial sessions? I suppose I could just pause a custom race and read it off the MFD. Is there a more elegant way?

Small aero changes can have a big impact because they affect the overall balance of the car. For the Hyundai, I have tuned the rear downforce to be just enough to avoid the back sliding through the Porsche curves. Indianapolis will give you an earlier warning* if you've done something very wrong.





* - It's really more of a "catastrophic loss of control resulting in certain death" than a "warning".

Oh yes, I have become quite familiar with the "Indianapolis warning" now. I have to remind myself every time I go into that corner to brake in a straight line -- a really straight line.

I did some additional aero tuning for the Hyundai in moderate rain (R04) on IM tires and managed to shave a couple seconds off my optimal time (starting from my dry-weather tune). Sitting at 3:31.441 now. I feel like there is still some room for improvement there, but I'll leave the fine tuning for later in the week.

Going to try to focus on a tune for heavy rain (R07) on W tires tonight.

I've also been deliberating if I should start working on a dry-weather tune for one of the Gr.C cars in case the race ends up just being a high-speed blast in the sun.

It's starting to feel to me like this race is going to go to whoever has found the best aero tune for whatever conditions they throw at us. Anybody who shows up on race day relying on the default tunes is going to be at a severe disadvantage.

I am curious to how GV is going to shake out.

For GT2, RH are mandatory but there is only a 1x on tires so it'll will likely be RS for all the laps but one...? But, there's also a 6x on fuel so that could come into play as well. Likely run on RS tires until you need fuel then put on RH for the rest.

GT1 is a tire x4 and fuel x2 so that one I think would just be keep running the RSs until you have to put on RH tires. If you can time it such that only one lap needed on RH that would be advantageous (like, about to run out of fuel on the penultimate lap, then pit for RH tires and a splash for only one lap).

Fuel saving will be a thing if you can get an extra lap or two out of the RS tires.

As usual, I'll let you guys have the fun figuring it out. I am not really interested in the Nations so already looking to the GV event.

Yes for GT2 it would be 9 laps with RS that's when fuel runs out and then 5 laps with RH. Doesnt seem worth pitting 2 times to use RS for 4 more laps.

Yeah in GT2 my early tests were a 1 stop race. Run the softs for max fuel stint and the rest on hards. Think it’s about 3/4 laps again like Dragon Trail.
I do think a no stop is possible in a few cars maybe. But it’s the offset pace difference between soft and hard that I think will sway it to been a 1 stop

Agreed, GV seems to be basically identical strategy to the Dragon Trail race, softs as long as fuel lasts (9 laps for me), hards for the rest. Tried one practice race and confirmed, end of 9 laps near empty on fuel, same as last time.

 

[SPL170db]

Probably going to sit out GV, heading to a friend's halloween party...unless I'm running late and can't resist getting a race in

 

[Roggers]

I’ve given up on testing Nations race. I’ve been testing my finger and controller skills to see if I can get my setup done within the 30 seconds timer. Why you can’t save your setup in the extra settings sheets 😡!
Just another stupid thing that PD can add to the list of stupid things.

Back to cars. Ive tried a few options tonight, Hyundai, Porsche (group c), 787b, GR10 and the 919… and the GR10 has to be my pick. While the GR10 isn’t the greatest car to drive, it still feels better to me than the others. Just hope I’m competitive enough in it.

Did a little aero testing at Special X to see the effects. Only did cars I owned.
Rules were to take the max MPH on the downhill bit on the bridge and then take a reading at 9000 metres after the car had settled again on the straight. Speeds all in MPH as that what I use, and also I can’t be bothered to convert them either 🤣

Car	Aero	Max speed on downhill (mph)	Max speed at 9000m/9km (mph)
GR10	Default	211	207
	High	204	200
	Low	217	214
787b	Default	229	226
	High	217	213
	Low	243	242
Porsche (Gr.C)	Default	223	219
	High	210	206
	Low	243	243

 

[Moose78]

Feeling reasonably well-prepared for the race now. I've got aero tunes for the Hyundai N 2025 for dry, moderate rain (R04), and heavy rain (R07), with optimal lap times of 3:21.961, 3:31.441, and 3:52.352, respectively. There might a little bit more time to squeeze out those with some more fine tuning, but I'm mostly happy with where I'm sitting with those.

I even had time to go back to the R92C and start on a dry-weather aero tune for it. I thought it was fast with the default settings, but that thing is a rocket once you drop the down force. My optimal lap time with it so far is 3.21.631, with a top speed of 374 km/h. Set a new FP best lap of 3:22.324 (IIRC), too.

My plan had been to us the N 2025 for any mixed weather races, but seeing that top speed from the R92C, it is tempting to see how it performs in the rain. Think I'll try out a few weather scenarios to see if it ever makes sense to use it in a mixed weather race.

Damn. Bummed I’m missing this weekend’s race, as well as next weekends GV race. Admittedly, I suck at both tracks…but group C cars are my jam.

What’s everyone’s opinion on the limited tuning they’ve allowed us in this FIA season as well as the daily’s?

Hopefully, it won’t get anymore involved then just sway bars and dampers. I think if they open it up any further than that (knowing that they’ve done exactly that for Nations this weekend), they run the risk of chasing people away. Not to mention, then car setup can really start swaying the odds drastically away from the casuals, and in the favor of people who are willing to spend hours testing. IMO, dampers and sway bars are the sweet spot. Offers just enough tuning where you can tailor the car to your liking, without it being overly-complicated

I'm agreed that either no or very limited tuning is best for competitive balance. I'm already not thrilled with alien-style tricks like dragging the brake in hybrids, I'm not super interested in finding out what kind of weird glitch tunes that full open tuning will demand to keep competitive.

 

[Roggers]

Hahaha basically did the same test as me but actually made it relevant and did it properly 🤣

Interesting to see from this video about how quick that Hyundai can go in the wet. 10 seconds a lap quicker... Convert that into average people pace, it what maybe 12-15 seconds?
I have to say I am enjoying this mystery surrounding what the weather will be doing that will potentially pick your car, but I’m not liking all these choices available and having to decide on a car. Plus add on all the time spent trying configuration on a long lap in multiple weather. Stressful!

So for the daily races I think the setups have been fine and are balanced about right. Just allowing damper and suspension changes doesnt really affect the top speed or lap times, all it does is just help the driver tailor a car to you driving style. Last weeks Manufacturers at Nurburgring I think was spot on. Anti rolls, dampers and suspension.

This issue I’ve found this week for Le Mans is you 3 categories or cars that all work in 3 different ways. LMP1, Group C and the VGTs. Allowing people to adjust the aero I think has just opened up was too many complications on this race and a few small glitches really.

I test the aero effects on a Gr3 car and I think allowing aero changes would be a welcome addition to the daily races and the speed differences is only 6/7 MOHs difference. I’m the same test on the old Group C cars the speed difference is nearly 40mphs

Car	Aero	Max speed on downhill (mph)	Max speed at 9000m/9km (mph)
Audi R8 Gr3	Default	178	172
	High	175	170
	Low	183	177

If PD are allowing setups then I do think they need to be more cautious about what category of cars they use and what options they allow is to change

Tuning allows you to tailor the car handling to your driving style and opens up more cars to be competitive. But it also increases the time commitment needed for a race and increases the gap between those who have lots of free time to test and those who have busy lives and just want to jump in and race. In the end, at the sharp end of the grid I find it doesn't really change anything. Every one is equally well prepared and you just finish according to skill level. The only difference is everyone has wasted more time preparing for the race trying to find a "perfect" tune.

If PD wants to open up tuning they need to increase the stakes of the competition to match the increased time commitment from the players. This will allow people to bring their own crew chief, have their own sponsors, and win actual prize money. Basically make it closer to the professional PC sim esports scene. Now some people might see this as good, but I think the reason why GT esports is one of the most popular ones is because of how accessible it is and the low barrier to entry. Everyone's in it because they just love racing, not because of money or sponsor requirements or other superficial reasons. You don't need to have a full team of engineers building setups and exploiting every physics loophole just to be competitive. This might sound selfish but I'd personally keep it locked setup for the official seasons. For exhibition, 1-2 tuning races for fun and variety would be fine since it doesn't count towards anything.

 

[RacingGrandpa]

While I think the tuning is fun it's detrimental to accessibility. The #1 force of GT in my opinion is it's accessibility and using tuning raises that bar.
And to be fair a proper different ed setup from the start would make it less necessary

 

[Nakano219]

I don't mind the suspension tuning they've been giving us, I don't think that it really makes that much difference to ultimate lap times but it can help people be more comfortable and maybe use different cars that have a default setup they may not get on with.

I'm quite uneasy about the downforce tuning this weekend though, that makes a much bigger difference - it's weird watching a Group C car go around the Porsche curves like it's a 919. And I really hope they never open up gearbox tuning.

 

[Fezzik]

No time to tune, no idea how to tune so I will be running a bog-standard Mazda or Hyundai tomorrow. Hopefully it rains or I will be swamped down the straights.

I'd rather they eliminated tuning completely and just made it a level playing field again.

 

[Talon16]

I don't like the tuning at all. As others have mentioned, I don't have time for it. I just want to jump in my car and race other people in their non-tuned car and go. Make the BoP as good as it can be (still a bit broken IMO) and let's go. I want to race other drivers, not their tunes they've spent 10 hours dialing in. It also makes it harder/impossible to learn from others' replays as you have no idea of their set-ups. This is why I don't play ACC as I just want to drop in a car and go.

I wonder how much it helps anyway and how much is placebo. In reading stuff here as well as watching videos, I've determined most people have no idea what they're talking about. And that's not from a, "I know everything and that is wrong!" perspective because that is 100% not true... but more of a bunch of contradicting information. If you want to reduce understeer one person will say to do "this" and another will say to do "that" which is the exact opposite.

Thus, you have to figure it out for yourself and...

 

[Met Entso]

I would like to know how to tune a car and all but for me just learning a track and and reaching good consistency and lap times is already high time consuming, so i'd say limit tuning to few variables as they are doing now.

 

[GlockPants]

This is me, also. No amount of tuning is going to make up as much speed as learning the track better. Aero, brake balance, tire strategy are sufficient challenges for me. Getting into spring rates and damping force, toe and camber, it's a bit much for a car you're going to run once.

I'm planning on running a stock tune with lower downforce. I'm used to reducing downforce for the WTC 700 so I think I'll handle it ok.

I'm just not sure if I want to go Group C or not.

 

[Moose78]

Mistah_MCA put this together, found it helpful from a tuning perspective. Now its just down to weather.....

I second that.

I gave his medium-downforce tune for the R92C a try and promptly knocked more than a second off my optimal lap time (down to 3:20.492) and set a new FP best lap of (3:21.324). That said, I'm not sure I'd use it for a race as it only reaches a top speed of 368 km/h, versus the 374 km/h that I'm getting with my previous best tune.

I couldn't get his low-downforce tune to work for me, though. I just couldn't adjust to the new braking points, so I kept missing apexes and incurring track limit penalties. Maybe with some more practice, I could get it to work but I wasn't getting there in the few practice laps I tried.

I like his tune for the Hyundai N 2025, too. It has significantly lower downforce than the tunes that I was using, so it requires a different approach to the corners. But that also means that it has a higher top speed in the straights -- 344 km/h versus the 320 km/h in the tunes I made. I haven't matched the optimal time of my other tunes with it, but it's only off by 0.3s so I'm seriously considering using it. That might change once I try it in the rain, though, which I still have to do.

What’s everyone’s opinion on the limited tuning they’ve allowed us in this FIA season as well as the daily’s?

Like @Nakano219, I don't mind the suspension settings, where you might be able to squeeze our a few tenths off your lap time with some tuning, but when it gets to the point where you have to tune to be competitive, like tomorrow's race, it's just too much.

If PD is going to make a habit of these kinds of races, I would like to see them make it possible to inspect the tunes used in the replays by the top drivers and easily apply them to your own car, so nobody is at a disadvantage.

Of course, having better tools to share tunes with other users would be a welcome change, too. The current technique of taking screenshots of the settings detail screen is archaic and painful.
