Gran Turismo World Series discussion

[Mumster]

No strategy this week. Simple sprint. Just go as fast as you can.

For me, that's probably not very fast. SH tires are my kryptonite so this round will probably be a write-off for me. We'll see.

I can’t wait for this one. The BRZ is great. Makes me wonder if there is any actual difference between the two. I actually like SH tires. It’s gonna be all about the racing line for this one.

 

[Skidude88]

Am I missing something?

Rd4, no weather, no tyre change, no tyre wear, no stops, no speed,

.....no fun?

 

[ZEE]

This was my race results on Saturday for the Round 3 of the Nations cup at RBR!

Managed a good 6th place overall! Had a very poor qualifying with a argy bargy all over. But it was good race I did enjoy racing the ring with the Porsche but a few dodgy French drivers didn’t make it too pleasant. But kept chugging and managed to finish in an ok position to net some points and rank up overall.

GT2 EMEA 1st Slot low A/S lobby 265 up for grabs, 11 on the doors

Qualifying you can only do 2 flying laps and with the penalty line location a penalty will ruin 2 laps. Managed to not get any penalties but did clip the wall on the last corner so slowed down both flying laps and managed a 2.16.705 which put me 12th, with pole on a low 2.15 so no great hopes for this race.

Opening laps are drama free with some great close racing but with nobody doing anything stupid. With the custom slip stream here it's quite important to stick with a group rather than trying your luck early as anyone on their own generally got left behind.

Lap 5 the shenanigans begin and a few mistakes up ahead give me a few places, then one Austrian driver is being a bit dirty up ahead, I got a run on them but then they squeezed me off the outside. They then caused more trouble with other drivers so I get past a group of faster drivers into 8th. A German ahead has a similar pace to mine and seemed sensible so started bump drafting with them to try and catch 6th ahead.

After a while they messed up the corner before the big straight so I had to leave them behind and could see the big group from earlier had caught up as well. So last lap I of course I pick up a penalty on T1 and can see that this 0.5s is going to lose me 4 places. The dirty Austrian driver from before has caught up and went for a dirty move on my German buddy, but they retaliated perfectly, sending the Austrian off without damaging their own race, and hold up the other cars, so I end up only losing 1 place in the penalty slow down, but amazingly that driver had their own penalty so I remained in 7th for 224 points!

Was a really fun close race with most people being very sensible and clean.

I have to say, practicing against Sophy all week for today's race has kinda soured me on this combo. So much dive-bombing and pushing-to-pass. I hope my actual race against humans later today is a little better, but I'm not counting on it.

Maybe I shouldn't worry about it, though. Being so slow here -- my best laps are in the high 2:17s -- means there probably won't be many drivers behind me to try dirty moves. We'll see how it goes, but my expectations are pretty low.

Best of luck to everybody who has yet to race!

All the best Moose, I had a terrible 1st race with being dive bombed on the 1st Q lap! Never recovered from that so had to race again.
Second race was better but some crazy 😜 Italian did not like being overtaken and slam dumped 3 cars on the final left corner and picked up a 4 second penalty and after ruining 3 others races he quit.
Fortunately for me I was behind said incident and slipped through to finish 9th after I made an error on lap 9.
Everyone was clean bar 1 so hopefully 🤞🏻 you’ll have a nice clean and fair race. 🤠

 

[VillaJ100]

Just did my race, Low to Mid GT2 lobby, went with the Toyota, qualifying wasn't great with a mid 1:18, Q10. Knew I could go quicker in the race and was lapping around 1:17.9 consistently, a couple of laps into the 1:17.5 and 6's.

Was in a fight with P7 and 8 for a few laps, thought I had blown it with a small mistake on the 'sequence' after T1 which put me a couple of seconds behind them but the lap time was only a 1:19.7 so not too bad. Reeled them back in and was back up to P7 soon, P6 made a mistake before the bridge and was way down on speed, tried to kill me going past and again at the hairpin but the gap was just big enough.

4 laps to go and was 3 seconds behind P4 and 5, but they were fighting every turn and I soon caught up, final hairpin on lap 9 they bumped each other and I went past for P4, with less than 1.5 second between P4 and P8, P5 conceded T1 to me on the final lap but ran wide and caused a jam that backed up everyone behind me and caused a 3 second gap so just had to bring it home safely for P4 and 70 points, about 6 seconds behind P3. P1 was miles ahead like a stupid amount 35+ seconds or something.

I think I'll be skipping this round. Summertime BBQ season along with Canada Day celebrations are taking precedence. Along with my woefully slow pace in my few laps of practice.

Good luck to all yet to race!

That’s disgraceful and another example of how the penalty system doesn’t penalise such poor driving 🥺

GT EMEA Nations Cup ROUND 4 - TOYOTA GR86 - B LOBBY GT3 - Door no.4 - Qualify 7th - Finished 6th place - TC 1 - BB 5

Well Round 4 was bit shaky and cakey with these foreign drivers play bish bosh with the GR86 all over the mountain. I had a real annoying Polish driver just start bumping me up the hill after the long left hander hairpin on lap 3. The guy drove like a total K**b, so is what it was and the guy had no penalty dished out to him for rammin into the barrier, thx game.

Overall a bit floppy race but I held it together to net some good points. Hopefully Round 5 a bit sweeter.

Spoiler: Racing photos summary

 

[Moose78]

Could've been worse. Could've been better.

GT2 - North America - 12 PM EDT - Toyota GR86 RZ '21 - 253 points available (top split!) - Door #8 - Q7 (2:17.525)

A better qualifying position, Q7, than I expected for the mediocre time I set.

It didn't matter a whole lot because lap one was a mess from the first turn. The car ahead braked more than I expected and I cut the corner as I over-adjusted. That got me a 0.5s penalty. At T5, I got pinched into the apex wall, which set me back to P10. At T11, I was pinched into the wall again, sending me down to P11. By the time I served my penalty at the end of the lap, I was down to P13.

From there, I put my head down and focused on putting in my best laps. As the race went on, I was able to climb back to P8, in the fight for P7.

But then came lap 8. In the heat of the fight, I cut T13 (pictured above) for another 0.5 penalty. I wouldn't serve that one until the end of lap 9, though, sending me back to P11 for the final lap.

I thought I might still have a chance to pick up a place or two through the first lap, but I pushed too hard through the sector 1 complex. I went into the grass coming out of T3, which gave me dirty tires and killed any hope I had of regaining some spots.

I finished P11 for 189 points -- my worst of the season so far -- for a 2.2% hit to my DR B progress, taking it to 94.6%.

Next up, Grand Valley Reverse in the X2019s. I'm looking forward to giving it another run.

 

[Wilsonson]

Wow that was a lucky drive.

I only managed a low 2:17 in my limited practice runs but felt like 16s might be possible. I consistently struggled with T1/T2 as well as the exit towards the long back straight though.

I was once again in top split of GT2 EMEA with 248 pts up for grabs.

Qualifying went terrible. Only managed a 2:18.8 for 13th.

I finally found my groove in the race and managed to stay out of trouble. I never once attempted to dive into any of those tight corners and tried to keep my overtaking to the back straight and of course capitalizing on other's mistakes. That worked to perfection. I had a single .5 second penalty at the beginning but it didn't hurt too much.

One after the other they punted each other into oblivion which resulted in a smooth 4th place finish. I was on P3's heels for the last 2 laps but never managed to get a clean exit towards the back straight. With a perfect exit out of the final chicane I could have maybe gotten them but that also didn't quite work out.

Bonus pic of me cruising by Q1 and Q2 (right and left of my Impreza tribute) who went toe to toe through each and every of the first corners for both of them to spin out here. One quit and the other never managed to recover.

Bonus pic 2: I have never been closer to DR A than this. It's about time I guess.

 

[Thorson1987]

Next round will be fun.

I'm guessing more strategy will be involved because it doesn't say that you have to use all 3 sets of tyres, just that you do have to change.

 

[Moose78]

Since this race is a repeat from Oct 25, 2025, I'm not planning to do any new testing. You can find the results of my original tests in the post linked below:

I've done some of my usual strategy testing. Results below.

Disclaimer: I feel it is necessary to mention right off the top that this reverse direction of the track is pretty much entirely new to me, especially driving the X2019 here. I've figured out a way to drive around the track. It's slower than @Zorz's, but that's normal. I seem to be seeing stronger effects of tire wear on my lap times than he did. This is probably a quirk of how I'm driving. This is all to say, take all these results with a grain of salt. What is true for me and my way of driving may not be for you.

I did test stints on each tire compound -- 10RS, 20RM, and 13RH -- in Custom Races against one AI driver, with the fuel and tire multipliers matching this round's. For weather, I picked early morning with S05.

I did a couple runs each of 10RS, 20RM stints. From those, I fabricated 'optimal' stints by picking the fastest of each lap. I only had time (and interest) for one run of 13RH. That's why the chart has a few spikes in it -- mistakes were made.

Summary:

Tire compound	Laps	Opt time	Best time	Avg time	Total time
RS	10​	1:28.719​	1:28.808​	1:30.211​	15:02.113​
RM	20​	1:29.600​	1:29.689​	1:31.085​	30:21.695​
RH	13​	1:30.882​	1:30.965​	1:32.227​	19:58.945​

Tire tread levels a finish:

Tire compound	Laps	Front Left	Front Right	Rear Left	Rear Right
RS	10​	35%​	25%​	20%​	10%​
RM	20​	35%​	25%​	20%​	5%​
RH	13​	70%​	65%​	60%​	55%​

Lap times:
View attachment 1487338

Simulated strategies:

Using these lap times, I can simulate various strategies for a full race. I assumed an additional pit loss of 17 seconds for the 2-pit strategies, which was an estimate based on the lap times @Zorz posted yesterday. I simulated 38 strategies in total. These were 5 fastest:

Strategy	Stint 1	Stint 2	Stint 3	Additional pit loss	Total time
10RS-20RM	15:02.113​	30:21.695​			45:23.808​
9RS-9RS-12RM	13:30.029​	13:30.029​	18:06.991​	0:17.000​	45:24.049​
9RS-8RS-13RM	13:30.029​	11:59.557​	19:38.368​	0:17.000​	45:24.954​
10RS-9RS-11RM	15:02.113​	13:30.029​	16:35.914​	0:17.000​	45:25.056​
8RS-8RS-14RM	11:59.557​	11:59.557​	21:10.055​	0:17.000​	45:26.169​

I'm surprised at how close the 9RS-9RS-12RM strategy is to the 10RS-20RM one. There are lots of caveats, of course, but for me, it looks like a 2-stop is viable. It would give me more options in the race, and avoid some of the dangers of driving on totally bald tires. It seems like it might be the right choice for me.

EDIT: All of the raw data can be found in this spreadsheet.

TLDR: I ran a 20RM-10RS strategy and came home with a win. Race report below:

I ran the first GT2 slot in North America at 12PM EDT. It was an all B/S lobby with 109 points on offer. I was in door #8.

I managed to get three flying laps in for qualifying, but the third was dud because I caught up to the driver ahead of me. No matter. The second was good enough: 1.27.589 for Q3.

View attachment 1487652

The race got off to a good start. The P2 driver must have not been expecting to start in first gear. They got a horrible jump off the line and I easily pulled ahead as we drove through the tunnel. Sadly, that's where my luck ended for the first lap. I was on RMs, planning a 12RM-9RS-9RS strategy, and getting way more wheel spin on the infield than I was expecting. I made a few mistakes and dropped back to P5.

As the race settled down, I was able to put in some decent laps and work my up the field. I was back to P3 when I pitted for RSs on lap 12. Came out in P5, in a nice gap with nobody around. That let me put in some good laps. Some of the cars ahead pitted, but I managed to catch and pass the leader on lap 19. When they went in for RSs on lap 20 about 2 second behind me, obviously doing a 1-stop.

I pitted for the second time on lap 21, coming out ahead of the former leader who'd pitted the previous lap. There were still a few cars ahead, but I figured they were either going to pit again or were trying an illegal strategy. As the laps went on, all but one of the cars ahead went into pits, promoting me to P2.

The leader was 8-10 seconds ahead and since they were behind me on lap 20, I figured they were running an RM-RM one-stop strategy, so I wasn't too concerned about catching them. But on lap 28, they spun on the final corner. That tightened the gap considerably.

Over lap 29, I was able to catch them. They were obviously struggling with their tires. I had the run on them on the main straight, but when I went to pass them, they swerved in front of me for a block. Despite running into their back, my tires were still good enough to make another attempt on the straight, but as soon as I had some overlap, they tried to push me into the wall. I wasn't about to sacrifice my race for this clown, so I stayed behind, biding my time for a good opportunity to get by.

That finally came on the final corner of lap 30.

They lost the back end. I zipped by as they attempted to recover. From there it was short sprint to the finish line for the win.

View attachment 1487655

That's 109 points and 6% boost to my DR. I'll take it.

BTW, it turns out the other driver was on a legal strategy. They'd pitted from RMs to RSs on lap 19. It's no wonder their tires were smoked at the end. I'm amazed they were able to make the tires last as long as they did.

Didn’t know BB was available for the race? I was using borrowed car and no BB was available.

Raced EMEA GT1 twice with Q2 at 16.1
First race with a P9 finish after coming back from a few small punts.

Second race Q3 at 16.3 and had a clean race landing on P1 due to the alien 👽 in P1 disconnect around lap 3.
Was down to 15.8 in free practice but was consistently over driving the car in race.

 

[Moose78]

Since this race is a repeat from Oct 25, 2025, I'm not planning to do any new testing. You can find the results of my original tests in the post linked below:

TLDR: I ran a 20RM-10RS strategy and came home with a win. Race report below:

As it turns out, this is not an exact copy of what we had then. The tire wear multiplier has increased from 4x to 5x this time. It seems I'm going to have to do some testing this time around after all.

 

[Skidude88]

Shame...I think they've also swapped out the required compound change, weeded out last time those who weren't serious and hadn't paid attention to the regs

 

[Mumster]

Did the 11 pm out of the 3 GT1 time slots q9 2:17:5 f p8 clean race. Happy with the result. Carnage in front of me the whole race people running each other into walls etc I was p7 at one point but I’m not fighting with those people so I let a couple through since they were faster anyway. 115 points best result so far.

Nope. It is still enabled. Everybody needs to use at least two compounds:

Thought my driving style has changed as I was shredding the tyres compared to last time - glad to know it is actually different. Now need to figure out if a 1 stopper is possible, maybe a H-M or H-S

 

[VillaJ100]

Thought my driving style has changed as I was shredding the tyres compared to last time - glad to know it is actually different. Now need to figure out if a 1 stopper is possible, maybe a H-M or H-S

It'd have to be H-M for sure I think with the tyre wear unless you were the tyre whisperer but H-S would be great if you could go hammer the final 8-9 laps on softs.

Early practice not going too bad but turn 14? The uphill hairpin is a helluva thing. Really hard to not understeer or get good traction on exit. I've done it a few times but seems more of a fluke

 

[Moose78]

Here's what I'm seeing. The most laps I can get out of each of the tire compounds is:

• RS - 8 laps
• RM - 16 laps
• RH - 21 laps

So that's what I tested. Custom race against a single opponent. S08 weather in the evening with a 1x time multiplier. I did two rounds of testing on each tire compound, taking the better lap from each round to compose an 'optimal' stint.

Here's a summary:

Tire compound	Laps	Opt time	Best time	Avg time	Total time
RS	8	1:28.750	1:29.023	1:29.685	11:57.478

RM	16	35%	20%	15%	5%
RH	21	30%	20%	15%	5%

Using the above lap times and assuming a pit loss of 17.0 seconds, I simulated 156 different strategies. These were the 10 fastest:

Strategy	Total time
8RS-8RS-14RM	45:19.829
11RM-19RH	45:21.138
12RM-18RH	45:21.239
8RS-7RS-15RM	45:21.404
14RM-16RH	45:21.638
13RM-17RH	45:21.831
8RS-11RM-11RM	45:21.862
10RM-20RH	45:22.145
15RM-15RH	45:22.160
7RS-12RM-11RM	45:22.800

Note: These simulations don't take into account the order in which the tire compounds are used, so for example 8RS-8RS-14RM is equivalent to 14RM-8RS-8RS or 8RS-14RM-8RS.

I'm not sure how accurate my assumption is for pit loss. If it is actually greater than the 17.0s I guessed, that would favour the 1-stop strategies. If it is less than 17.0s, the 2-stoppers become better.

I'm glad to see there is RS-RM strategy at the top. I didn't enjoy driving on the RH tires, especially once they started wearing down. The thought of avoiding them altogether is very appealing.

 

[Skidude88]

Can't find any info....on the 'Data logger', there's a middle Tab 'Collection'...what, who, why, how?

Wondered if there was a way to load my fastest lap from last October's NC rounds (almost) copy. Can't seem to tag or mark anything as a 'collection'

 

[Wilsonson]

Pretty sure you can only load laps of the exact same event. Therefore your old one doesn't work.

 

[Moose78]

Now that I've done my basic tire tests and identified some viable strategies via simulation, I'm trying to understand the differences between 1-stop and 2-stop strategies. I did a single full 30-lap test race yesterday for two representative strategies: 18RH-12RM (1-stop) and 14RM-8RS-8RS (2-stop).

They came out pretty close overall:

Strategy	Opt time	Best time	Avg time	Total time
18RH-12RM	1:28.779	1:28.922	1:30.901	45:27.031
14RM-8RS-8RS	1:27.929	1:28.089	1:30.892	45:26.747

But how they get there is quite different. If I set up a virtual race between the two strategies, the gap between them looks like this:

You can see how the 2-stop strategy on the RM tires immediately pulls away from the 1-stopper on RHs. When the 2-stop goes in for the first pit stop, they come out 6s behind. They have nearly caught up to the 1-stopper just as the 1-stopper goes in for their first pit on lap 18. The two stay separated until the 2-stopper goes into the pits a second time on lap 22. This is where things get interesting. The 2-stopper comes out just behind the 1-stopper. The 2-stopper gets by the 1-stopper on lap 25, but their lead shrinks as the tires wear out towards the end of the race.

I find myself leaning towards doing the 1-stop. In the early stages of the race on RH tires, I don't really have to worry about getting held up behind a driver on harder compounds, and I might even be able to hitch a ride in the slipstream of the drivers using softer ones. Towards the end of the race, I'll be defending rather than attacking. Even if I just let drivers on faster compounds by without a fight, I might be able to stay in their slipstream and mount an attack at the very end when their RS tires are dying.

There are risks, of course. Being on the RH tires at the beginning of the race increases the likelihood of getting punted off in one of the many hard braking zones by drivers on softer tires, who may not be prepared (or willing) to slow down enough to avoid contact.

The risks for the 2-stop are more about getting held up. On the RS tires especially, I only have 2-3 laps where the tires are actually faster than RMs. After that, they are on-par or slower. If I get into traffic during that window, the tire-compound advantage just evapourates, and I'd still have to contend with the slow laps at the end of each stint.

That's how I'm seeing it, anyways. What are the rest of you thinking?
