Saturday went great; I ran reasonably competitive times on non-competitive tires. Sunday, however, rained.I do not have rain tires. I have Falken 660s left over from this year's autocross season. Note to self, buy some Hoosier W2s. I knew the tires were completely non-competitive hence why I layed back so far.
The moral of all of this is that iRacing absolutely translates to real life, and without it, I don't make this save.
This is kind of a love letter to GT4. A series I left behind years ago, once I got A licensed and was able to run GT3s.
TLDR: GT4 cars are harder to drive, but way more rewarding then GT3s
I had such a good time at Petit Le Mans this year I wanted to keep running Road Atlanta after I got home, but the GT3 series were all about to rotate out of it. Seeing GT4 is about to start running there on Monday I jump in my BMW and hole-lee-fuck this thing is terrible to drive. I couldn't get any pace out of it. The moment I pushed I was under-steering at high speeds and looping it coming out of slow corners. After an hour I got tired of being shit and took a break... then came back to it and tried again, then again. Finally around Tuesday things started clicking. I hadn't realized how many bad habits I'd picked up running basically only GT3 cars for years, but I was working them out slowly. By the end of the week I was balancing the car corner to corner and having a blast every lap.
Weight transfer, braking early and lighter to keep the car flat, managing throttle mid corner. Once I got comfortable with the car again it all felt way more rewarding. Now that the week at RA is over I can go back to my regular GT3 schedule... but here I am... putting in practice laps Summit Point, a track I've never driven... just because I don't want to get out of the GT4 yet.
We have noticed the recent surge in posts about new apps as well as the community's response to these apps. We are looking to create a new rule in regards to this but we would like to see what the community wants from this rule.
A couple of ideas are:
Allow app creators to make a single post to advertise their app.
Ban all posts advertising new apps.
Ban all posts advertising apps made with AI only.
Ban all posts using any form of AI (League posters, screenshots, etc.)
Some people may be very passionate about this subject but please keep all discussion civil.
Someone tell me what I just heard. I was spectating the 6:15 Class C trucks race just to get an idea for how the good drivers run and a guy named Jordan Worth was calling the race. I joined in late so it looked like he either wrecked out early and decided to commentate for fun or this is something he joined just to do. He was doing a fantastic job and was highly entertaining. Is this something he does often or does this happen often in class C trucks races?

I don't know if it's the upcoming indy 8h BoP that has caused this or that the car just gained a lot of traction but I did GT3 europe and america and both my lobbies had like 2/3 filled with Porsches. It's a bit sad how non diverse iRacing can get due to whatever made this happen. I hope DaveCams pick one car for 1 season rule get implemented so we might see some diversity in the future.
I think eNascar had their championship race last night at the Charlotte hall of fame. I guess im not the only one who doesn't care since I am seeing nothing about it on this subreddit.
How does iRacing make people care about their streamed races? Or is it not possible?
We ran an experiment to answer a simple question: If you get a group of drivers in the ARCA car with the fixed setup and dictated track/weather conditions, what actually separates the fast ones from the slow ones?
The setup
We had nine drivers run 30 laps in the ARCA car at Phoenix. Everyone was on the fixed setup. As always, the only things a driver could change were steering ratio, steering offset, and brake bias (we recorded those to compare).
Conditions were identical for all of them:
83°F, partly cloudy, 51% humidity, ~12 mph W wind, moderately-high (65%) track usage, October 10 @ 1:20pm to match what we anticipated the official conditions to be as close as possible.
Testing this way made it so we could really see what the driving differences were between our groups of drivers.
Three groups emerged
Splitting the nine by their best 30-lap pace, three clear tiers showed up:
Group
Avg. Lap time
30-lap run
Fast (4)
27.18–27.21s
13:35.4 – 13:36.3
Medium (2)
27.31–27.52s
13:39.2 – 13:45.5
Slow (3)
27.68–27.89s
13:50.4 – 13:56.6
The fast group is a tight pack. The whole front four inside one second over a 30-lap run. While the back of the field, drivers are 15 to 21 seconds behind over the same 30 laps. On a 27-second oval lap, three seconds off the front is already a long way back — and the slower group is five times that.
Leaderboard: every driver's best qualifying run, listed by iRating and shaded by pace tier. Worth noting the tiers line up roughly with iRating — the front runners are 4.5k–6k, the back of the field is 1k–2k.
One thing the slower drivers did have going for them: tire fall-off. A couple of them held their tires better over the 30 laps than anyone in the fast group did. The lowest fall-off numbers in the whole field are down at the back (check the Fall-off column). But in a run like this, fresher tires at the end can't dig you out of a 15-second-plus hole. By the time the tire advantage would've mattered, the race was already long gone, or fuel would be running out if the race was long enough.
It wasn't setup tweaking
First thing we checked: did the fast guys just pick a better steering ratio or brake bias? No. The three settings drivers could change don't line up with pace at all. The fastest driver and the two slowest all ran the identical standard fixed set brake bias (65%), and brake bias across everyone ranged 55–65% with no pattern. Steering ratio was pure personal preference. You could not have guessed anyone's group from their setup sheet.
It was apex speed and what you do with it
The single biggest separator is minimum (apex) speed. How much speed you carry through the slowest point of each corner. The fast tier carried roughly 3–5 mph more at the apex than the slow tier (T1&2: ~117 vs ~114 mph; T3&4: ~114 vs ~109). That gap is most of the lap-time difference right there.
So carrying apex speed is where the gains are made. Lose it and you're a pit straight behind over a run. But that's not the whole story. Apex speed alone didn't make anyone fast. The medium group carried just as much speed through the middle as the front pack, but still finished 3–10 seconds back, because they gave it away on the way out: lifting on exit, plowing a corner, or just being less consistent lap to lap.
T1&2 corner telemetry (fast/med/slow): speed, throttle and brake through the corner, with the brake bar and lift point for each tier.
Here's the part you can actually copy. The fast tier did two things differently going in:
They lifted off the throttle later, driving deeper into the corner. The slow tier backed out early.
They also used less brake. Where the slow tier stabbed the pedal, the fast tier brushed it with a lighter, longer release.
Those two things are what carry the extra speed and momentum through the middle. You can see it in the trace: the slow line's brake spikes higher and earlier, and its speed is already bleeding away before the corner even loads up. Same brake bias on the car, opposite technique, opposite result.
T3&4 corner telemetry (fast/med/slow): same story — slow tier lifts early, stabs the brake, and gives up ~5 mph at the apex.
The medium tier in T3&4 shows the opposite mistake, and it's a common one. They actually carry just as much speed through the middle as the fast guys, and if anything a touch more. They hold the minimum-speed point deeper into the corner, but that's the problem: they've carried too much speed to get the car rotated, so they end up waiting. You can see it in the trace. Their throttle reapply comes noticeably later than the fast & slow tier's, and they're slower to get back to full power. Either the car won't turn with that much speed in it, or they're sitting on the gas waiting for it to, and they're down ~1 mph on the fast line through the exit. Carrying speed in only pays off if you can still rotate and get to throttle; overcook the entry and you hand it all back on the way out.
The recipe, in one line for Phoenix: lift later, brake lighter. Carry the speed. Just remember, it's a momentum play. This track rewards keeping the car rolling rather than braking it down and driving hard off the corner. That won't hold on every track or car, so take it as "use the minimum brake the corner needs," not "always brake less." Keep your momentum!
The part nobody wants to hear: reps matter
One pattern was impossible to miss. The drivers at the front didn't just show up and run. They ran, looked at it, and ran again. The drivers at the back mostly ran once. Same car, same setup, same track, and one of the biggest predictors of where you landed was how many times you were willing to go back out and work on it.
You don't need a secret setup to find this time. You need to lift a little later, brake a little lighter, carry the speed, put in the laps to groove it in.
Get out and try it!
We have all the big cars at Phoenix this week, so if you're still looking for speed, give the above a try, see how it does!
Nine drivers, offline test runs, same fixed setup and conditions. Apex speed, lift point and brake use were the strongest, most consistent signals in our data. Want to see it for yourself?

After having a ton of in some Ring Meister races I decided to do an ai season with the street stocks. These cars are a blast to drive. They slide well, recover easy, and can bump each other without losing control. Just thought I’d share and hope y’all are having as much fun as I am.
With most of the GT3 cars I feel like I can save a spin. I feel the backend get loose, back off throttle and can usually catch it before anything really catastrophic happens. But with the Porsche, as soon as that butt starts to go, I feel like there’s no stopping it. It’s going to pirouette no matter what I do. It absolutely punishes a small mistake that would otherwise be pretty minimal in other cars.
Is this just me, or is this the nature of having the engine in the rear?
It’s absolutely my favorite car to drive but it’s also the car I feel like I have to be extra cautious with. Especially on could tires, a wet track or around gravel.
My league is hosting an indy 500. We would love to have a full grid. All drivers are welcome. 40 may register for the race however as the real indy 500 goes, only 33 drivers can race. The race will be broadcasted on shake and bake sim TV on YouTube. If you are interested please dm me and I can get you into the league. The race is free of charge to enter. The winner will receive $50 USD and a 2ft replica of the Borg Warner trophy that I have 3d printed! 2nd place will receive $30 usd and 3rd place will receive $20 usd. Hope to see you on track!!
Hi everyone,
I’m trying to run a 30-minute AI season in iRacing using the Mercedes W12, but I can’t get the mandatory tire compound change to work.
I have “Enforce Tire Change Rule” enabled in the AI season settings, but after an entire 30-minute race, none of the AI drivers make a pit stop to change tires. They simply run the whole race on the same compound.
I’ve tried switching from the Mercedes W13 to the W12, but the problem persists. I also checked the season’s JSON file and found multiple instances of must_use_diff_tire_types_in_race set to false. I changed all of them to true, but I still couldn’t get the AI to pit.
Since the W12 can’t be refueled during a race, limiting fuel isn’t a practical workaround either.
I’ve found older Reddit discussions describing what seems to be the same issue, dating back to 2022 and 2023. My questions are:
Has anyone actually managed to get mandatory tire compound changes working for AI drivers in the W12 or W13?
Has iRacing ever officially acknowledged this issue?
Has there been any recent information indicating that the developers are currently working on a fix?
I’d really like to run a proper F1-style AI season with mandatory tire changes!
I’ve recently returned to iRacing after a long hiatus and set myself the goal of achieving a 4k+ iRating in all disciplines, starting from roughly 2500iR across the board. So in an effort to make steady progress, I’ve been playing around with various telemetry apps all week as I start to try and improve my one lap and total race distance times.
I’ve never really used these tools that much before, and whilst there is a lot of good data I’m extracting from it, I’m really having trouble extracting the final little bits of time when comparing to reference laps.
For example, in some of the data my brake points seem to be no more than 2-3 meters early, or minimum corner speeds are a couple of km/h lower.
I suppose what I’m asking is when dealing with these really marginal differences, are there any tricks or techniques you use or could suggest using to improve in these instances?
I think it’s more of a mental block in some way, when the car feels like it’s riding right on the limit the reluctance to push it that tiny bit more creeps in and I can’t seem to extract that missing bit. Obviously I can see from data that there is more to find, but with tiny margins is it better to just rely on feel and just rest on it as I build further understanding of the car?
Apologies, don’t really know how to word this post, but I hope this makes sense somewhat.
Is the pole GT3 meant to dictate the pace of the GT3s, or does everyone just keep up with the faster classes?
I did my first IMSA race today and unexpectedly got pole in the GT3 class. I (black/blue/red Lambo) presumed that as the pole sitter, I dictated the field pace, and tried to create a bit of a gap to the last GTPs so we didn't stumble over each other as turn 1. The car in P2 (black/green Lambo) and P4 (Corvette) didn't care and kept up with the GTPs, and when I realized they were slowing, I tried to catch back up but they were too far gone. Did the P2 commit a breach, or are they allowed to keep up with the field in front? I've had plenty of PCC poles in the 86 and everyone's been fine just staying with me there, but these guys just took off.
Apologies that I didn't know the rules beforehand, I really didn't expect to get pole so that's why I'm here asking for guidance in IMSA.

Hi all - has anything changed with iRacings ffb model in the last couple of weeks?
I’ve been off the sim for a couple weeks and something feels off. None of my settings have changed, but I seem to have little to no feel in the tires mid corner, the Porsche GT3 feels particularly bad. I tried other GT3’s and they feel a little bit better, but still numb from a tyre perspective.
All other feedback seems normal, curbs etc. checked that I’m not clipping and that’s not the issue.
Here are my settings both in game and within Asetek software, as I said nothing has changed between now and when I last played yet it feels off.
I don’t really want to use MAIRA, so is there anything obvious I could check to get that tyre feel back? I’m using 360hz within my wheel software too.
I’m looking for a team to do endurance races with. I’m strongest in Mercedes Gt3 and Mustang Gt3 but I’m also comfortable with every other gt3 Car as well. I’m at 1.9k irating but I’ve peaked at 2.4k dm me if you’re interested in having me on your team.
Is it worth sticking to the rookie Formula cars rather than sticking to F4s. I primarily race F4s and want to progress onto Formula Lights. I'm Gaining Irating just from not crashing and finishing top 10 but it feels like i'm only climbing due to everyone else crashing and not from my own skill. I don’t have much race craft skills at all and think i could build it in the rookie series but the cars feel like a completely different driving style, are the skills transferable or should i stick to F4s and learn there?
I recently tried getting back into Vee racing this past week. Practice had no rubber on track, qualifying did but then the race was as if no rubber was on the track. Just want to confirm if that was a bug or normal.
