Love Sonoma. It flows so well. Those tires were screaming for their lives. Looks like a track alignment and a fresh set of tires would knock a few seconds off. Sub 2:00 would be pretty quick especially for your first time there. Keep up the good content.
I would honestly go there with a set of good fresh tires before installing everything. That can probably make A LOT of difference.
When that GT3 passed you I had an eargasm. Sweet Jesus that sounded good
Big Gran Turismo 4 vibes. Tire Squeal and all.
Was thinking the same thing
I think you drove pretty well considering the poor tires and alignment. Looking forward on your next videos. 👍
Oh dang I was at this event. Think I saw your car on track. I watched from the garages. Was in the black Speed3 in a different run group. You looked super quick from my vantage point hehe.
I'm missing out on all this fun right in my own backyard. I would love to do this. I will do this!
Do it! I used to live in California before covid but had to move for work. I never went to these tracks the whole time I lived there and I regret it
I'm not sure if used budget tires are what I'd bring to the track, unless I'm just messing around....
I bought these secondhand since my OEM tires chunked. Definitely not the tire I'll be using for time attack!
@@Zygrene the ps4s chunked? That's not great
@@Zygrene Whats chunked? sounds like chucks of tire coming off?
Also what is MAOU?
@@JeffMartinEquinox Yeah, literally chunks of the tread block coming off. "Maou" is the "Demon King" of the Touge in Hot Version! For years (and maybe still today?) it was the J's Racing S2000
@@Zygrene Must of been defective. Can you put on PS4s tires as part of the category you are aiming for?
The 200lbs added weight can testify the understeer was real.
After one lap I remembered that I knew This Track from Forza Motorsport. 😂 looks fun! Can‘t wait for the GR86 to come to europe. Probably going to trade my GT86 in for it.
Great driving, like all the in-race comments added. Definitely seems like a tire issue for the hairpins, you'd think the car wouldn't understeer that badly as you weren't going that hard
Can you review the 2022 mx5, they added brake based torque vectoring they call it kpc kinematic posture control. It handles and turns in alot better and has less body roll. Nvm guys the kpc system is useless it turns off with stability control off, because if ur running aggresive track pads it makes it act weird, plus it doesnt make the biggest difference to begin with.
If anyone has a 2022 MX5, please shoot me an email!
Its an interesting feature, they use the ABS system to brake the inner rear. Not sure how good/bad this will be for track though.
Whats the lap diff between the brz and f82 M4?
I live in SoCal but Sonoma is my favorite California track.
@zygrene what gloves are you using? Do you have any favorites you've used? Some gloves seem to thick, lessens steering feel.
Awesome videos i love how much you share about the car. Living vicariously through you until i can order a 2023 model. Really looking forward to the alignment and camber adjustment to see what the results are. Sounds like the stock alignment is very tire friendly in terms of wear on public roads. Does the car feel more nimble on the 17s as opposed to the 18s?
Not that I could tell, but the 17" tires with taller sidewall do ride ever so slightly better than the 18"
Get some better rubber and once you get the feel of the track it's such a fun track!
I was looking for my Z but I'm in group 3 so probably not on the track at the same time
Tires for sure. Set of cup 2’s would take care of all your understeer issues (even with stock alignment, as there are buckets of grip once they reach operating temps) but of course you’d get maybe 2-3 of these HPDE’s before you have to throw a fresh set on… pay to play ;)
Cup 2s are not what use on these cars for time attack 🤣 pretty much there a few 200tw tires for time attack. Nankang, Yoko, falken are pretty much the top 3 now
Why would you recommend cup 2’s. You the type to go the cheat route instead of the more challenging route.
@@piercetm Dude wtf
@@piercetm not sure I understand your comment, but with that kind of logic I guess everyone using slicks at the track are cheatingx2 rather than care about grip. Tires is the first thing, before you start messing with suspension geometry
@@JFlogerzi I have sampled it all (besides Nankangs, which I hear great things) and for some strange reason, I keep going back to Michelin. And I don’t work for them lol
Can you tell me which part number for those power stop pads? and is that the Nsx air pump lol
thanks
PSA-1124 and PSA-1539, and yes that's the OG 1991 NSX air pump lol
Just wondering if tire squeal is heard and if that means more tire wear in the corners.
Yes and yes
Which adjustable rear lower control arms you planning to use?
PLM Billet Aluminum
That right hander when you're coming down hill and kept putting two off on the left.. Most cars will have a tendency to understeer there due to the weight shift forward and you're braking. It really shows though your tires just losing grip and the car needing a better alignment. There's a similar/slower sort of turn at my local track. At the risk of being captain obvious, with the current state of the car (in this video) I'm thinking you have to take that turn slower as coming into that turn too hot the car won't rotate and you just push off track. Following the s2k's line doesn't work for a stockish 86..? Either way nice videos man!
First time ever at Sonoma, or just first time in this car?
The track will absolutely expose any weakness in handling and weight-transfer stability (of both car, & driver lol)
Part of what makes this circuit so brilliant.
First time at Sonoma in any car. I've done countless sim racing laps but the real deal is even more challenging.
@@Zygrene first time on any track or do you have experience out there? Never done track yet and I have a wheel, is it worth trying iRacing?
New brz owner here. Do you recommend any camber adjustment for street use or just track, if so how much?
Highly recommend doing the SPC adjustable lower camber bolts + OEM upper crash bolts. I was able to get -2.6 camber which greatly reduced understeer in canyon/track driving.
No idea what data the Garmin Catalyst gives, but it'd be great to compare your speed through various corners when you get the suspension upgraded.
I should have a Catalyst by the next track day!
How are the track day pads holding up so far ?
Holding up great. Still plenty of pad left and no fade with PS4 or SX2.
4:50 maou, Hahaha
Can you run Hankook rs4's? They are the same rating as the champiro. I've really liked using the rs3 on track and will definitely go for the rs4.
RS4s are a bit faster than the SX2s. I am curious how good the new RS tires as most old twins ran 17x9 for track and the RS tires only in 18s
RS4 will push me into the Unlimited class unfortunately.
hi！how about the oil tempreture?what oil do you use?thx!
Max oil temp was 255-260F I think. Running 5W30
Are you running with 86DC by any chance?
Nope, planning to run 86CUP events through SpeedSF in California
Just a little entangled with brz or nd2, which car has better cornering performance? I already ordered the new brz but when I say your s2000 nd2 video, I start entangled.
As a 19 BRZ owner i'd say ND2 all day every day...
ND2 turns better, hands down. It has double wishbone front suspension and is much lighter.
Could you try recording in-car with the fake engine sounds unplugged?
I heard the engine is almost inaudible with this unplugged, but I'll give it a shot
That would be great. Not really any good videos showing the difference in sound. Here's an instruction video: ua-cam.com/video/H-EUBupvQ7o/v-deo.html
lot's of fun content! Do you anticipate needing an oil cooler for the warmer days?
I think it's likely, but so far my oil temp hasn't gone past about 255-260F
@@Zygrene awesome. I just took delivery of a white manual base model gr86. Thanks for the fun vids, I'm subscribed and look forward to more. I'm from the Bay too I'll probably run into you somewhere I'll definitely introduce myself. ✌️✌️
The 2022's have an oil/water oil cooler setup. Not sure if that will be up to hot Cali summer sessions though.
my 19 BRZ is an understeering pig! Much preffered the GT86 tuning from stock i had before...
Seems like old and new models both suffer the same understeer from factory. I'll find out for sure at my next track day. Will be trying a stock 2020 BRZ.
@@Zygrene That would be interesting to see the comparison! I reckon you'll find them similar.
I have crashed so many cars here... In Forza!
3:03 lol
don't worry. the SX2 don't grip any day. new, old its low grip
This is true. Great learning tire. I think with a better alignment ie more negitive camber the SX2s would do better
@@JFlogerzi what is a "learning tire"?
@@JohnZhu1988 lower grip, a tire the communicates and tells you when your on the edge of grip. Something's not just on/off. Also sticky tires cover up mistakes as a driver. Which means you will need to unlearn bad habits later on.
@@JFlogerzi i feel like sticky tires are better to learn on, but that comes from karting i guess
Surprised you didn't go wider on the tires?
He is going to be running in the gt86 cup in stock class so there is a limit in size and treadwear
@@JFlogerzi Touring class, which means I can still run up to 255. My competition setup will probably be 18x9 with 245/40/18 or 255/35/18.
@@Zygrene you running the TRD cup or Northern 86cup?
@@JFlogerzi 86CUP in California
can u send me link to the track pads you got?
Just search PSA-1124 and PSA-1539 on Amazon
@@Zygrene is that for front and rear? cuz when i found them they both say they are for the rear.
That's too bad a car like this lacks any negative camber out of the factory. Looks like stock spec's range is centered around 0 degrees, which is an odd decision.
If it's like gen 1 I think it's roughly -.7 up front and -.5 in the rear. I could be full of shit though i don't remember.
5:36 when you're beta testing a game and the tire clips through the track geometry
What actually happened there? The tire squeal doesn't make sense to me
I actually have no clue but it was pretty disconcerting
Those tires just seemed lame honestly, and I hate understeer, the new mx5 understeers too much IMO too. It’s not enough to make you hate the car because you can correct it but it’ll never handle as good as my heavily modified mr2 spyder.
