- Laguna Seca... No matter what you may think of its many previous names and sponsors, it is one of the most iconic tracks in North America. It is also one of my all time favorites, with many millions of laps driven on the Good ole' Forza 4. The competition was extremely strong, but we gave it our all!

Its amazing how i can relate with all turns just from driving in Assetto Corsa. The sketchy downhills that unbalance the car under braking, the fast full commitment where camber really allows you to carry lots of speed and the T1 with the double apex and a understeer magnet. Even the oversteer at the exits happens exactly the same way when using a M3 GT2, for example. The way the car hit the curbs, the track limits, all perfect. Really shows the quality of the work that some guys put on AC and Sims on general.
I remember going and I didn't even think you would be out on the west coast and then I saw ur car in the paddock and it made me so happy man. Really enjoyed seeing you drive irl for the first time.
Just to let you know, BMW have launched an official racing version of the M2. It would be cool to see a comparison between your tuning and theirs.
AGREED, LET'S BUMP THIS COMMENT!
We saw it! It looks like a fairly stock car with minimal suspension and safety modifications to make it suitable for track use. Think of it as a GR86 Cup car or a MX5 Cup car, just slightly faster!
@@JackieDing86 Out of curiosity, would you have bought it if you didn't already have your current M2?
We had the previous generation m2 racing with our team. It didn't have more power as stock when we got it. Just adjustable suspension, cage, and some carbon panels.
@@TheTechnoaddictbasically a stock m2 that is track prep think stock m2 with track tuned suspension and grippy tires.
You are a great pilot, your efforts, tenacity and desire will be rewarded. Cheer up and the next race will be better Jackie.👍
neat to see your analysis of the track, couldn't agree more. had a good laugh when you asked for downforce and Alex was like nope you ain't getting that!
hope to see you back on the west coast in the future...maybe gridlife will do Sonoma for some real theater.
It's amazing the tires held air. Also amazing that this issue was missed. You could hear it slapping the car.
Great video and great competing against you and everyone else! I always love seeing other’s POVs from event weekends. See you next year!
Costly and frustrating but thanks for providing another data point on the downside / unimportance of stiffer sway bar on multilink suspension. Should be considered only to fine tune setups as a last option. Now more aero!
I can't agree more with the rule changes for the Podium Sprint with literally zero communication. This has happened MULTIPLE TIMES this year with rules being bent or formats changing. It's total chaos for the competitors, those running the livestream, and most of all the people watching. I love Gridlife with all my heart but I REALLY hope they tighten that up next season.
Yeaaaaaa, I share that sentiment. I love Gridlife but sometimes it just feels like it's too loosely regulated. It was fine back in 2018, when most of TA was just glorified HPDE, but now in 2024, with so many ppl putting so much effort and finances into it, it's hard for competitors not to feel hurt or screwed at times.
That corkscrew exit hurt you big time, I think you could've been real close to the 30.6. Looking forward to COTA and being able to utilize all the camber. 🤘
1:30 around Laguna Seca is no JOKE.
I cant wait to see some more upgrades to this thing 🤙🤙
I hope H&R is watching this right now.
Great video man!
nice video and great competition overall.
In my opinion a great 4th place, the track seemed not to be easy at all.
just keep going
If you were checking tire temps after runs you would have realised that the camber wasn't optimal.
I was surprised by this. They should have noticed the wear immediately, at least to figure out setup
You need a way to make the 10 increment OEM traction control work again.
Always looking into how to get it back online. It would be an extremely useful tool for sure.
Is the factory TC timing or brake based?
If the bars are an issue, should have tried just unhooking the rear as test.
Heyo! it was dope to meet you there! Hopefully I can get a car together and join everyone on track at some point!
Since it is still a street-ish spec, I suspect it is still mechanical grip>>>aero grip reliant on setup. (in addition to slimmer side walls on modern size tires) From my understanding, aero cars do have stiffer bars to limit floor height fluctuation for stabilization. Im not sure if there is any but having adjustable sway-bar setup could help with the setup in the future.
You're absolutely right, the car is still more mechanical grip than aero in its current state. So making the car excessively stiff with the bars just overall hurts grip.
We're still working with Eibach on adjustable sway bars for these cars, but now we know not to go crazy stiff compared to OEM!
@@JackieDing86you’ve got the luxury to work with big companies! Hope both of you and Eibach could develop a good one!
Jackie great videos as always, which product gives you the HUD when editing your videos? Throttle, Break, Oil, Gforce, Speed, Track radar etc. Thanks
Anti roll bar swap back ? 😜😜😜 looking forward to see more about the M2🎉🎉🎉🎉
anyone know what exhaust muffler + midpipe setup is on this?
G87 M2 doing G87 M2 things
💪💪💪
I never seen you dancing with any car like this Jackie!
The S2000 had some of these moments back in the day. That shit was wild
Let’s go ! 😎
God it loves to slide, good save and amazing skills
Friction with rubber that thin only works well if you're not planning on using it twice. ;)
Exhaust and upshifts sound awesome! Shorter FD I’m guessing?
Drivetrain is all factory!
Do you have a rough estimation of how much roll stiffness you have fron the roll bars and how much you have from the springs?
If not done.. Or for sure tried. If the rear sway is adjustable. Set to full soft?
Maybe try H&R Front sway bar and oem rear sway bar with stiffer bushings than the rubber factory
Sure you will easily get this m2 sorted quickly
Disconnect the rear sway ? Just for a lap or two?
Disconnecting the rear sway is a bad idea, as the unconnected sway bar has a chance of catching on the barrel of the wheels under heavy cornering. Also this would cause significant understeer and I think it would just be a temporary bandaid.
That would be undriveable. Especially when driving s-turns you would have very snappy behaviour.
I know some of the max attack BRZ/86 guys are huge proponents of no rear sway bar. Would that work for a G87?
Gordon Murray, too
@Shadowboost I think there's enough other factors going on with the t.50 that it's not the best example, but valid point.
@@justinbecker4772 not just T.50. essentially his entire career of car design
First comment 🎉
I wanted to suggest a few things. I know the car is being developed and many changes are soon to come. Now I know from what BimmerWorld was saying that those H&R’s are very stiff and heavy. And optimizing your setup would definitely need to happen to make car grip and be forgiving (softer spring or something idk).
Buy if your looking for more compliance but slightly less roll, may I suggest sway bars from the M4 CSL? Evolve Tuning did the M4 CSL sway bars and front hubs (which have build in camber) and gave excellent reviews. Not many people have done this but I believe they are on to something. Combine that with a CSL steering or Chasssis flash for the diff or trans and so on. And you might see nice result that will mix better with the rest of your mods.
Also CSR is coming out and might have some specific parts you could borrow but not much news on that car as of the time I’m making this.
Lemme know what you think def would love to brainstorm !
we actually went to the CSL sway bars right after this, so you’re right on the money! :)
@ 🥰🥰🥰 I love being a genius. Definitely let us know how it’s goes I’m so excited to see what changes come next.
you fucking did it! LFG!!!
20:20 SENDING it down the corkscrew. 180 degree steering input. 🙈
oh and again at 22:00 lol
So, as it was a heart broken 0.2s, what about let Jimmy Diggs have a try?
Stock sways for the win
a picture says a thousand words they say, if I could send you one picture it would be of Alain Prost in the pits and the team had the F1 car on a precision flat and he patiently sat there as they worked on the F1 cartat
To what extent do you think the handling issues you're having do you think are due to the typical high weight car problems? Need a really stiff suspension setup to manage the weight, which makes it unforgiving at the limit?
I've also generally been under the impression that you should get most of your stiffness from springs and shocks and run the smallest swaybars possible that give you the handling balance you want, especially in the rear where having a very stiff bar would make putting the power down harder - seems like that might be shown in your experience with the sway bars here.
Changing the shootout rules partway through the season sucks though, feel for ya on that for sure. Great driving in a not ideal scenario!
I don't think it's a weight problem, it's just the sway bars being extra stiff caused more harm than good in this scenario. I think what you mentioned is correct!
Dude run the 3R when you are allowed! They are another league from CRS and A052.
pirelli motorsport 💪💪💪💪
For reference GT4 race cars do 28's 27's.
We will beat it next year, 100%
@@JackieDing86 With ease. I seen it.
they named it Supra for a reason :D
This thing needs a diff controller badly. That's what's making it a bear.
Soon you guys may break a record with 1000khp track lap record instead of a drag time record with xxx amount :)
You know what would fix this car? A K swap
The M2 is really heavy. I hope you can find some way within the rules to take more weight out the vehicle. To dial in the suspension and tires I believe you need more data. Try dataloging shock travel and tire temps using infrared sensors over the tires. If you cant measure it you cant improve it.
Whyd it look like you had terrible oversteer
THE WEST COAST CURSE CONTINUES
Hahahaha. At least nothing broke!
@@JackieDing86 Are you doing the GTA finals???
Just get a cayman man
That's on the list down the line!
What about a lotus?
@@JackieDing86wow amazing
Very cool! I just bought a sim system and was struggling or am struggling on LS. So I got some pointers from you watching you run it lol. Apparently I need to slow down in a few of the counters. Always good content! edwjohnson83stx.
