Winter 2021 Finale | Thunderhill, Buttonwillow, and Laguna Seca

[@niikon]

6:39 "How has my car not blown up yet", it's a Honda 😚🤙 Cracking into 1:40 on Laguna Seca, damn Jason you're a beast!

[@aRandomAggie]

That second half of the Laguna Seca lap was video game style full send!

[@DIYGuysvideo]

I'm most proud of that lap for sure

[@NAUS2K]

Nice Job man! I'm sure once you move on to a better suspension you will see yourself increasing the stiffness of that front bar again. That and having the front camber at almost -4 will dial out that understeer.

[@DIYGuysvideo]

Soon man!

[@evgeniyhaydamakha1652]

Dude, these numbers are unbelievable for a basically stock S2K. Such an inspiration!

[@brunomanco7529]

Wich shows that apart reliability mods, 255 tires and big brakes its basicaly all u need in a s2000 (cr stock suspension might also be a notch above regular s2000 suspension, and cr rear wing might also make some diference)

[@kimlevi44]

Your content has helped so many of us!! Glad to see you’re doing well for yourself!

[@Mugen-zkY]

Saw you a few times at Thunderhill and wasn't able to say hello, like your video, keep it up, man!

[@equisdos2431]

That bottom corner at Laguna Seca is always a challenge ! Great in car angle.

[@jasontong2218]

Crazy you're still on stock CR suspension and the fact this car has so many miles! Long live the s2000!

[@Nalos2012]

Enjoy your vids, keep them coming

[@Diiwfus]

That laguna seca lap was nuts.

[@sleepy773]

Good stuff! Pretty impressive time with the stock dampers

[@aznheadbanger]

Man I picked up an 08 berlina cr in September and will be tracking for the first time with vtec club at the end of the month. Been watching all your vids to prep the car. Thanks for all the how to's and inspiration!

[@DIYGuysvideo]

You're welcome! Happy to see other CRs being driven as they were designed to!

[@Wpham7]

Glad to see you guys posting again!

Bro, You're absolutely killing it. Keep it up man! And kudos for driving such long distances with out a trailer 😬

[@DIYGuysvideo]

Thanks dude

[@xANDRExFLC]

Awesome!

[@mr.hernandezdrives]

awesome stuff man, s looks very fast out there

[@tonyyang7989]

what a beautiful s2000! it caught my attention that you have a bumper quick-release install any chance you can do a quick explanation of the product?

[@rolandotillit2867]

I was wondering where you were!

[@W33lhop]

Can you slow down, fast boi? Ok thx. -Nemesis

[@JAHgarage]

Great vid and fast laps! Seriously impressive with a relatively stock s2k 👏🏽. Need to get my ass back out there soon

[@chubby_miata]

Has been incredible to watch your growth as a driver over the past 5 or so years. Is there anything apart from seat time that benefits time attack preparation?

[@alexlai2580]

I remember when Jason would come out to meets and was young and super enthusiastic! Damn, you’ve gotten fast, your channel is probably THE DIY resource for our platform!

[@chubby_miata]

@@alexlai2580 we've witnessed an evolution of a Sadboi to a Fastboi

[@DirtDude117]

So I dialed in more oversteer by swapping to a NC1 soft top FSB on the rear of my AP1 with the Karcepts front bar. I wish I could still sell you tires but can't wait to see you break more records!

[@toddxhiggins]

Swapping to a smaller/softer/more compliant rear sway bar would just throw even more bias to the front and cause more understeer. The mx5 rear bar is used by a lot of auto X guys to minimise rear wheel spin and excess sliding.

[@toddxhiggins]

Great stuff! Still awesome to see you doing small changes bit by bit and getting the most out of each set up. Very similar to my philosophy. It's nice getting out on track and beating much more built examples that are nowhere near as well set up.

[@DIYGuysvideo]

Thanks dude!

[@s2k_rob]

Very good. :) Greetings from Germany

[@Rob.Coleman]

Good stuff, looks fun 👍.

[@sbfd3s]

I think the "need" for a large front sway bar on a square setup is greatly overstated unless you are doing an auto-x setup. My friend ran a 1:53.9 on BW n/a with ao52's and he is on the stock 07 sway bars. I also have an 07 but I have the stock rear sway bar with an Eibach front sway bar. On stiff (slightly stiffer than an 00-01/CR bar) I had too much understeer so I put it on soft (about the same as the 08-09 bar) the car started to handle much better. I'm still thinking of putting my stock bar back on the front as it is still a little pushy at times.

[@toddxhiggins]

Agreed! I see so many comments saying you need to go big front sway bar the moment you even think of changing to a square set up. Annoying as in most cases it's not needed and the person giving the advice hits the track once every 3 years haha. I went to a square set up on my 01 (largest OEM sway bars) and even with the stock front bar I still had a touch of understeer to iron out so can imagine how bad it would've been with an aftermarket bar.

[@brunomanco7529]

I was going to go with CR Springs + koni + eibach front sway, but will try with oem 01 to check this. At the moment im on stock suspension and 16 inch wheels and 205/245 tires

[@massimilianozeni1848]

wow!bravo!congrats! always liked the fact that you could drive your OEM staggered s2000 so fast that I almost feel bad that the squared set up is faster ahah. In Italy we can't change tire size, I wish I could drive an S with 245 all around. I kinda did like your friend (Nat?, the other super fast guy) and bought a showroom s2000 only to find out that I love to track it. It's a bit of a pity but it's really addictive. Did my first few mod after 2 years, Ohlins, alignement and Recaro Rsg and I love how the car feels now but I really need more seat time (and better tires) in it. I live abroad and the S is my summer/Xmas toy only. You drive it very well, I wanna hone my skills too. Priority number one is always to bring the car back home in one piece for now :) Nice recap of the last few months. Does the big brake kit handle heat much better than the stock rotors/calipers with good pads? Well done.ciao!

[@karltaht2370]

Your driving is absolutely clinical! Looks like the Karcepts bar had the same experience for me. Too stiff. Objectively fast but not nearly as fun to drive.

[@Getsomepiggy]

Car is gonna be very fast once you fine tune the suspension to work with the square setup

[@maxymillion7480]

Seems to be consistent quality problems with Stop Tech. I've no idea why people opt for them when theres alternatives from other high level motorsport providers. Are they much cheaper?

[@PatrickHidden]

I really like karcepts, but I agree with you about their front sway. It's crazy stiff when looking at the numbers and comparing to other FSBs. I've always had an eibach FSB on my non aero s2000. I like it. What tire were you on for that 58 lap at bw?

[@DIYGuysvideo]

Maxxis RC-1

[@PatrickHidden]

I honestly enjoyed seeing those grids on there…. Positive is if you bend a wheel you can get another in a week or less. But overall love the content man

[@DIYGuysvideo]

I already bent one loooooooool

[@_anonico]

No issues with Rotas? Thinking of picking up some Slipstreams for track only… can’t justify huge spend on nice wheels that might break

[@DIYGuysvideo]

Well they bend easily so maybe consider a forged wheel 😅

[@ghunmayang5672]

Can you do a video on how to do a Quick Release Lock Latch for the Front Bumper ? Like your videos helped me out a lot on DIYs

Likely won’t sorry.

Amazing driving! How much mileage do you have on the drivetrain?

[@DIYGuysvideo]

Thanks. The CR is at 164K now

[@petahlee]

@@DIYGuysvideo Like you mentioned in the video, amazing how it's holding up even with all the hard miles! This really is a Testament to how well this was put together.

[@i-barg]

Awesome! My new favorite s2k channel! What are you thinking for lightweight wheels? I

[@jrlude_]

What's up man? I've been a subscriber for a while and was hoping you could help pin-point an issue with my AP2 by picking your brain. I have a 04 s2000 with 115k miles. 10/10 vin, garage kept. It is pulling to the right (significantly) since I messed with my ride height. It is on Ohlin's coilovers. Thought an alignment would fix it, but nope. Alignment is good (camber, caster, and toe) (lets take this out the equation) Tires are good. However, I've already flipped both fronts (left to right) and rears (left to right) just to make sure. 32 PSI all round. (lets take this out the equation). Car drove straight no issues on the same tires. So if we can take alignment and radial pull out of the equation, could I pick your brain on what are the potential things to check?

[@kumingo]

How much of a spacer did you run on Cr wheels? Did you run any spacer on rear as well?

[@gooey41]

Do you have any brake ducting for the front/rear? Thank you for all your content!! It has helped me immensely.

[@DIYGuysvideo]

No I don't. I had ducting for a brief period on the front of the car but once I went to a big brake kit I had to remove the dust shields on my wheel knuckles. In the rear I'm using the Urge vented rotor so it typically stays quite cool.

[@ccramer3712]

What tires are you running on the street vs the track? I’m going to move to 17” for my AP1 with a supercharger install within the next year. I do not plan on rolling fenders was hoping to stay around AP2 OEM staggered specs.

[@DIYGuysvideo]

I don’t daily this car so I just run the same tire to and from the track. Maxxis RC-1, Yokohama A052, or Falken RT660

[@ccramer3712]

@@DIYGuysvideo thanks I appreciate it. Keep up the good work, your videos have helped me get my S back out of the garage.

[@Tony-ui8eg]

love the vids, was wondering if its needed to have aftermarket roll bar for track day? i dont have hard top..

[@DIYGuysvideo]

Typically you don't, at least out here on the west coast. The S2000 technically has factory rollover protection which allows you to run without an aftermarket roll bar.

[@Krazy_Shorts]

Fuckin A, this looks so fun!

[@Jazzybo]

How do you like the rotas? I may go that route for just tracking

[@jaimehurtado356]

Hello, I have watched many of your videos! I recently purchased an AP1 and live near button willow so I want to get it out on track however if Inspect my valve retainers and find no cracks would I be okay tracking it or should I replace them even if there is no signs of cracks?

[@DIYGuysvideo]

You are most likely to mis shift if you have broken motor mounts and you are not driving in a bucket seat. Having said that I have overrevved my AP1 a few times in the past without issue. If you’re a beginner you’re more likely to miss shift but I wouldn’t make it a barrier for getting out on track.

[@jaimehurtado356]

@@DIYGuysvideo thank you, yes I am trying to go in the next two weeks but if I have to do new keepers and retainers it might be another month or two. How’s the F22? I’m contemplating a k swap once the motor goes my AP1 is high mileage I picked up up crashed for cheap and have been fixing it since

[@DIYGuysvideo]

F22 is great and solves all of the F20s issues. K series may be more expensive than you’d think.

[@jaimehurtado356]

@@DIYGuysvideo good to know, thanks again! I will continue to watch many of your videos as I work on restoring my S2k

[@rolandotillit2867]

Lift off oversteer is chassis warp, if you want to run the big front sway bar you need a ladder brace to go with it. The big swaybar links the front axle more than the rear and the chassis twists and bends a bit. With the front and rear subframes linked you transfer more of that front axle twist from the larger sway bar to the rear.

[@ncrx1]

How have the Rota Grid's held up?

[@DIYGuysvideo]

They bend if you don’t treat them nicely. Can also crack if you go wild but I’ve primarily sustained a few bends from Thunderhill west which is notorious for bending wheels.

[@pvogel]

I absolutely love your channel, and appreciate the work & time you put towards the videos. But, those wheels are nothing but a downgrade from your previous AP2v3’s. Wider? Sure; but, they’re much weaker. Point being: I’d go with a quality wheel! Specially when you have a such a nice build already!!

[@DIYGuysvideo]

I do plan on going with a forged wheel soon. I just wanted to finally go squared. Evasive was coming out with a 17x10 that was supposed to arrive in June and I don’t know what the hell happened with that. These are temporarily wheels until I can find something proper. I’ve already bent one of the rotas at Thunderhill west heh

[@pvogel]

@@DIYGuysvideo Why not source some 17x10 +50 Ce28’s from ICB? (They even have a 17x10 +70) Perfect fit for stock body, great quality wheels, and if I’m not mistaken they have some in stock!

[@DIYGuysvideo]

I looked into CE28 and they generally have poor BBK clearance. With a +50 I would have to run a 5mm spacer. Then the wheel becomes a +45 and you’re looking at installing extended studs (hubs and bearings) on all four corners. Obviously if a +50 won’t clear a +70 would be even worse. Even now, I can’t turn to full lock without the grids scraping my front suspension (probably due to the offset ball joints). TE37 at +47 is more doable with a 3mm spacer on stock studs but that is down to a +44. I like Titan 7s but they so don’t do 10s and I have a lot of friends that have bent them pretty easily. Advan RS2 +50 would be perfect but they aren’t produced anymore. I have a connection at Apex that is interested in building an s2000 spec wheel based on my feedback so I’m going to try and explore that.

[@i-barg]

@@DIYGuysvideo If you do get Apex to create a wheel... I think we can get enough people in for a group buy.

@@DIYGuysvideo Also - have you considered 949 Racing I think they do 17×10 +52

[@moustachio334]

It’s unfortunate you had to move to a square setup and now have to deal with understeer. I personally don’t like square setups on RWD cars for this reason unless they are pushing large amounts of horsepower. Seeing as your S is mostly a track car, you won’t have to deal with the terrible side effects of driving a square setup on the street.

[@DIYGuysvideo]

Well after I moved back to the stock swaybar that understeer is gone and the car feels great. Its also nice that I can rotate wheels and tires front to back. I'm able to get 1 more track day out of tires which is really nice.

[@chasethemdreams]
