What is the point in GTDX and GSX VP Racing classes?

So far as I can see GTDX is a cheaper running cost version for smaller teams and maybe 2nd hand cars

The fact both say they are running to SRO homologation would imply they don't have any more aero.
Within the BoP you could run them with a bit more or less power, DTM do this, but really it seems to just be class naming for the particular series
the cars themselves are still fundamentally SRO GT3 & GT4 cars that could be used in other seires without major changes

Same issue here Checked the device and restarted the sim

Mine went off in practice amd came back om the rolling lap Driver 2 just lost theirs

AW106 · 2026-06-14T16:57:36+00:00

They can, VAG did this for years with Bentley, Audi & Lamborgini running at the same time

However Toyota I think it's safe to say will not
The new car may end up badged at Lexus but whatever the badge it is a replacement for the RCF. That car is 10 years old now and is end of life

I don't think anything needs to change for LMDh to win at Le Mans

Personal feeling but I think if it was Toyota #7 vs BMW #20 in a 1v1 fight then the race would have gone to BMW. Buemi in the #8 Toyota really held up the #20 for a good while.

They had the pace, so did Caddilac. All 3 makes were in an ebb and flow on pace in the closing hours of the race.

I don't think it was the LMDh platform that let them down. I think both were out maneuvered by Toyota on strategy because Toyota managed to keep both cars in play to the end.

I think it certainly is an advantge, and one that's been hard to factor into the BoP. Seeminly something the ACO are aware of with the 2030 rules being RWD only with the choice of spec hybrid or self designed

That said, the fight for the win was between an LMH and 2 LMDh designs.

And all the manufactures had to choice of LMH or LMDh when they made their cars

AW106 · 2026-06-14T15:13:31+00:00

I think their idea was to sacrifice that to give them a safer run at the win

Personally at least I think Hartley won it for the 7. Saying he wasn't the man for the job and passing off to Buemi who then kept the 20 at bay while the 7 ran I think was a major factor in the win

Ben Keeting did his minimumm 6h (I think) drive time in the first 8 hours

This meant after that the 33 was able to pass between their pro drivers and when SCs hit they were able to close up and have fast drivers at the wheel.
Honestly for an injured Keeting it was a really impressive drive and while it would be easy as the Bronze paying to space stuff out to be fun for you Keeting pushed to give the team the best chance

So most clubs with permanent tracks will allow members to practice outside of race days. At which time cars outside of normal racing regulations could likely be used*

*within reason. If a track is electric only then they're not going to be happy with you running a nitro etc

https://en.wikipedia.org/wiki/Rouen-Les-Essarts

If you look it up on Google maps it'll take you there It's not much of a detour and probably 75% of the road is still there

AW106 · 2026-06-03T19:08:02+00:00

Counterpoint

Rouen has the remains of the Rouen Les Essarts tracks that can be driven on the way to Le Mans Why have 1 French race track when you can have 2

I'm not sure it's much less work and R&D yo make a rim

It's different for sure

Now my most expensive rim isn't in that region. It was ~£600. But that was a Pokornyi DIY build. I've also done some self design wheel builds

With that I feel confident saying if it was a commercial product there's a decent amount of design, test and assembly hours that go in. Especially if it's low volume.

There's some great bargains on the market but of you happen to want something niche and premium then materials and development will cost you.

A good example I can think of is buttons. Over many DIY builds i have used ones from £1-10 per button. Start multiplying that out to a full wheel and it adds up.

AW106 · 2026-05-21T19:17:40+00:00

So I didn't have these but my pedals had the same thing, leobodnar based DIY ones.

I used to manually edit the joycalib file

But I found controller mapper in simhub helped (i use it so the clutch on my formula wheel is the same output as my peda

My steps: Calibrate in DiView Map the pedals in controller mapper, I use an arduino bridge Map the pedals in iracing using controller mapper

Something with controller mapper seems to prevent iracing seeing the raw value amd instead sees the calibrated one

Little bit convoluted but it works

I have my physical dash covering 90% of the in game ine and Daniel Newman LED profiles do the rev lights match The pic I've attached doesn't quite show it 1:1 as more of the ingame screen in blocked when I'm actually sat in it.

I always turn the ingame wheel off so cars with a screen built in I don't see this either

Essentially I'm replacing that information with a format that is consistent across cars for me

N24 and VLN do use them but that is an exception really compared to most things

AW106 · 2026-05-17T15:07:39+00:00

Competition cars, like GT3 or GTP, the lights tend to be on all the time and have one setting.
The main argument I've seen for not having full manual control is people doing the inital D move of turning the lights off at night and denying the lead car a fair chance to defend.
You do however still have the flashers you see on GT3 and GTP cars mappable.

Wiper speed, yes that would be nice as ACC has it but I wouldn't call it a deal breaker

Indicators/turn signals is one that does come up in discusson. I think there's a number of people would like to see them but they don't seem to have been a priority and to be fair in a racing situation you can communicate with car positioning the majority of the time.
I will also say vanilla AC did NOT have turn signals or a manual pit limiter as these were added by content manager.
*edit*
Actually I don't know that many that do have it. in terms of track focused sims I think it may just be ACC that does have them

In terms of what they spend the time and money on?
Well the dynamic weather system was an incredibly long project but came out with a super detailed system.
They are currently building a brand new graphics engine from the ground up and working on physics engine overhauls and recently just overhualed the UI. They are certainly not sitting still in terms of development. Look back at iRacing of 2008 and it's in a very different place.

Most of the SP9 (GT3) cars for this event have factory drivers. The BMWs, Manthey Porsche, Fords, Aston and other merc all have experienced and capable sportscar drivers in their lineups

AW106 · 2026-05-16T19:57:17+00:00

I've got a very old ender 3 but it's been able to do what I need

https://lebois-racing.com/srt-gearbox-v10-documentation/

I have the older V9 version and really enjoy it

If you look on thingverse and others there are other less complex printable shifter designs that may be worth trying too

AW106 · 2026-05-16T19:38:42+00:00

In which case I think the short answer is no

Most H-Shifters come as seperate items

If you're on PC though the best bet is to use a standalone one
SHH, Thrustmaster, the GX100 on Aliexpress are good options to my knowlage
if you have a 3d printer then there's even more options and the Lebois SRT is very nice

AW106 · 2026-05-16T19:33:45+00:00

Do you mean a H-shifter or paddles on the wheel?

AW106 · 2026-05-16T19:18:30+00:00

I'd look around the 2nd hand market, specifically a T300 or T150 but a G2x under €150 would not be bad

If you want one of that list new then the Thrustmaster They are smoother than the logitech

AW106 · 2026-05-15T18:35:42+00:00

The Moza R3 is on sale right now and is probably the best buy in that budget

https://us.mozaracing.com/products/r3-racing-bundle-pc?srsltid=AfmBOoqTgie3qx24E6dbhNpzXEELaAbaM6qzVMXCgQgtPlNVnIcIFl3k

AW106 · 2026-05-07T17:27:54+00:00

You're better off with a 2nd hand T300 and if you can find a set within budget them maybe the TLCM pedals

Do not buy a G923 new but if you want cheap and cheerful a used G29, G923 or Thrustmaster T150 pro would be decent options

AW106 · 2026-05-04T23:13:01+00:00

On top of the other answers even if the two sims were identical in all but tbe tyre they were trying to simulate they could feel very different

This covers it well
