They finished the race? If the race time was set to 30 minutes and they passed the finish line after that, then they finished the race a lap behind others.

Back at it with my FIA GT1 grid. Lamborghinis need a bit of a dial back in power or some extra weight added. Still, great battles throughout the grid. Here's half an hour at Suzuka for you to enjoy .

Just flipped through your channel and you've got some awesome custom races on there, do you have anywhere where you have posted the builds for the grids?

That goes for everyone doing them really, perhaps we need a thread somewhere with car builds + setups for Classic DTM, 90's JGTC, TCR etc etc. Apologies if there already is one, but I haven't noticed it.

Gran Turismo 7 Custom Race thread

Do you guys know if things like fireworks and jets flying over the track also happen in custom races?

I know this DTM tune/setup because I bookmarked it haha.

So I just did a 30 minute Gr.3 race at La Sarthe. All cars were mine. Race was a good one and came down to me winning the race on the last lap with Roxy the Porsche 911. Anyway,that's besides the point. I noticed this weird thing happen. I was watching the map while racing and was wondering why there were two cars lagging way behind in the last few laps of the race. The replay showed this:

So weird. Fuel was good, tires were good. What, they just decided to both call it quits?

They had to call it quits - time was up! This happens on the 700pp 30-min race, as well, or any timed race (as opposed to lap count). Clock strikes 0 after all but the final 2 have crossed the line, so the final two “end” their race, ultimately having finished 1 fewer lap than the others. Notice the chequered flag next to their names in the leaderboard.

05XR8 put this beauty together, I’ve referred to this for old school DTM/‘87-91 Gr.A.

I have a few old grids that aren’t recently polished but can still give a pretty good base:

IMSA 2024 (WSC - Gr.1s and Gr.3s; MPC - Gr.4s and tuned roadies)
NASCAR (Tri-oval-tested only, recently)
Muscle Cars
LMGT1/LMGT2 (lots of good posts in this thread covering “90s Le Mans”)

For the latter, I keep the Gr2 trio together (CLK, McLF1 Longtail, GT-One) as one class and then use tuned road cars as the GT2 class. Here’s a decent reference, but it’s also not too time consuming to look up the wikipedia pages for each year’s running of Le Mans and notice which cars have street versions in game. It’s quite a large chunk of them!

As you can tell, I like to replicate! Have been having just as much fun in the ‘Career Mode’ options listed in my signature, which may not be what you’re looking for but genuinely create dozens (hundreds?) of unique custom grids. Lot of clicking around the menus and really helps to have one of each car to begin with!

Thanks for checking it out 👍🏻. My YouTube has become a dumping ground for my custom grids. If there is one you're particularly interested in, I'm happy to upload the cars and their stats.

The 2000 JGTC one would be great whenever you get time please!

Are the Classic DTM builds that @Gingerale posted of yours from '23 still used or have they been heavily modified since then?

Ahhh got it. Makes sense. I've never noticed that in the 700.

For that grid I just use the three cars (NSX, Supra, Skyline) under bop with liveries. Quite easy to set up, that one.

The DTM grid remains the same

A year ago I had revisited this Rolex set up using the Toyota GT-One(tuned to about 605 BHP) instead of the Peugeot. With SOPHY it should run much better.

Now that we have the perfect car for it, revisiting my old grid.

I stick with Group A as it’s cheaper and most diverse in what cars I put together for whatever region of a series(DTM, JTC, ATCC, BTCC, ETCC). Super Touring(using the road cars) are my next most used cars for the same reasons.

 

[Revengel]

That is a capital idea. I may have to try this and see just what happens using my 590 race. Lately the same couple of cars are at the front . . . but they start near the front so that's not a surprise.

Might have to try this out at dinner tonight.

Tried this last night and it seems to depend on where different cars start. May need to experiment more. Ralph Philips (IYKYK) does normally come in first in the Porsche Club RS with Dom in the neon colored Supra normally in second.

I was watching the map while racing and was wondering why there were two cars lagging way behind in the last few laps of the race.

So weird. Fuel was good, tires were good. What, they just decided to both call it quits?

They did it in protest the mis-treatment of the dual clutch transmission.

 

[2cam16]

Today was test day for my Porsche Cup races. 6 laps at Spa with my 12(so far) 911's with some liveries that I copied from the Japanese cup racecars back in the day and some my own. All stock cars except for SS.
Decent race. I thought it would be more exciting and close quarters but I took the lead in the third lap and it was over.

Hello folks,

I'm sorry for the basic question: Is it still best to run boost on weak, for those of us not blessed with a PS5 and Sophy?

I always find custom races so frustrating, as there's so much potential, but it really frustrates me having AI randomly speed up or slow down to create a false sense of competition.

Even as flawed as the AI seems to be - unless I'm missing something - it has been great fun creating skins based on the UK-based CSCC series and running facsimilies of their very varied grid in-game.

 

[05XR8]

Yes. You’re better off running Boost Weak to at least have the AI “battle” you for P1 to the finish line.

When racing against non-Sophy, you additionally need to solve for the 95% throttle ‘bug’ (deliberate design?), which isn’t addressed by boost=weak. After loading up the pre-race, adjust your own car’s tune to reduce power to about 95% (will vary between you/me/etc., the car, sometimes circuit). I just keep it on a separate tune sheet so it’s easy to flip to once you find the appropriate balance for a car in a grid. It’ll be important to train the habit of flipping back to the ‘normal power’ tune sheet every time you finish a race. For some reason - and I haven’t tested in a long time - it seemed to me it wasn’t enough to launch the pre-race with the lesser ‘human’ tune sheet selected, so adding this nonintuitive step (and undoing it) EVERY time I raced was the convention I landed on. Still do it! Have honestly had just as (if not more) challenging races against Reggy as I am having against Sophy. Just need to give the old dog a fair fight

 

[Revengel]

Just to share something as a follow up to my Sophy 590 Cup Post I made earlier in this string.

I've tinkered (and continue to play with) the staring order and regularly get fantastic results. I shared the replay here:

Sophy at Spa - 590 Cup

Feel free to enjoy; I may post this to YouTube later on this weekend. If folks want the tunes I used, let me know. I can post screen caps here either in this string or in the tuning string.

This is really interesting, I'm fairly new to the game and was wondering how to make the regular AI more competitive. Is there any other way to make a fair battle, other than changing to inferior tires?

 

[pritchyTim]

Inferior anything, really. @PirovacBoy had some of the earliest tests, waaay back in the thread, and seemed to find his comfort zone upgrading brakes/pads/clutches on AI cars…it’s true they can be particularly slow in the braking zone.

I usually find a nice home at 91-95 on the power restrictor (with that pre-race trick…my comment history elaborates beyond what I posted yesterday if it isn’t crystal clear). That’ll depend on the human - I was in B league back when I did my 50 races in Sportmode hell. Am certainly a better driver today. If you overnerf your own car, you can create ‘samey’ races where you dog it down the straights (even at <100% throttle, the AI WILL be capable of reaching top speed, and you won’t, and you’ll fall back on every straightaway) and exclusively pass/make up time on that one corner or subsector that the AI just plain stinks at.

@Theufcveteran was the one who suggested I add a convention for shortening my transmission a little to better control the balance. In theory, with a shorter transmission (closer gearing/lower topspeed), I have the advantage over the AI on corner exit, keeping me in slipstream as the AI builds its natural (BHP) advantage down the straight. When you get it just right, you can ride slipstream into passing opportunities in the braking zone and create realistic, fun racing.

Some people use fuel mapping to slow themselves down, probably not in conjunction with an inferior tune sheet. The AI uses assists and traction control, so if you have fun matching that (I don’t), that could balance things a bit. I haven’t played around with suspension or aerodynamics when it comes to self-BoP, that could be a neat topic to have a handle on. @Bazool does some awesome stuff with old cars and seemingly quirky suspension setups. At one point, long ago, I read some thoughts in here that the AI was quicker with LESS downforce, given its ‘on rails’ tendencies (probably doesn’t apply for Sophy, at least). Idk about that so much, it probably depends a little on what sorts of cars are in your grid, too.

Last thing that comes to mind is exactly that - the cars in your grid. Try as we might for perfect balance, inevitably you will learn which cars in which grids provide easier/harder win conditions for you. Maybe one car just has that extra oomph, or one is just planted and super easy to get to do what you want. There are some days I just, secretly, want to whoop on the AI, and I’ll get in that car that day that helps me do so. On the day where I prefer a tough challenge, I know which car in which grid will deliver. The same can be said about circuits - my signature ‘integrale’ links contain a tab I keep as a ‘report card’ of sorts, to note which circuit layouts have better/worse AI performance. Open to co-contributors!

These are the thrills I try to recreate. Same speeds, attitudes of the cars and closeness of the racing.

 

[N-VEE]

Just got done doing a GT300-style race around Suzuka Circuit. Was a fun experience overall.

I pitted in at lap 9 out of 21 for some reason and was thinking to myself, "damn, this probably was the worst strategy I've tried doing lmao"... until all the Sophy drivers ahead of me began pitting in and before you know, I took the lead with enough fuel to last the whole race and tyres that were definitely showing signs of wear, but weren't completely shot. I almost got killed by the TEAM UPGARAGE NSX on the final lap when it tried to go for an overtake on the hairpin corner. Overall it was a fun race.

Now that I think about it, I should probably update the GT300 grid since TEAM UPGARAGE now uses a AMG GT3 instead of the NSX...

Anyways, for anyone who's interested in what race settings I used, I attached them to this reply. Have fun and feel free to provide any feedback and suggestions!

This one is for sure a glitch as this is the second time it's happened. Gr.4 custom race. 10 laps at Road Atlanta. I'm in the Cayman. My custom livery AND SEVEN other cars reverted to stock livery other than mine which is who knows what livery.
Michelin Raceway Road Atlanta _ (20) by 2cam16, on Flickr
For comparison, the second place car is what the livery should be. It also affected a Silvia,Scirocco, Supra, R35, Renault, Aston Martin and an NSX. Other weird thing is they were all behind me at the start but there were also cars behind me that were ok. A couple of weeks ago when I ran a Genesis in a Gr.4 custom, it too lost it's custom livery. Otherwise this was a fun race at the end as you can tell by the gap. We were trading places on that final lap and were inches away from each other through the esses!!

If your custom liveries don’t show up, go into the event settings from the pre-race screen, change a slider like the race length or lap count, save it, then go back in and revert the change and save it again, the liveries should appear as normal.

 

[05XR8]

I just restart the race if liveries have not fully loaded after I cross the start/finish line. Also, if I’ve made changes to liveries, I go to my garage and select each car I’ve changed. When initially selected, all the decals won’t be on the car and it’ll load them in a couple seconds. This helps the liveries to load when I jump back into racing.

I really appreciate your very detailed post with all the information you just shared. Thanks a lot!

I have lots to catch up with, and lots to try and experiment. One of my favorite tracks are sardegna and Saint Croix, and sadly those don't have Sophy support at the moment. I'll try messing around with some of your suggestions and report back how successful I am able to be.

Thanks a lot!
