The Ultimate Nissan S Chassis REAR Suspension?

We've got a new project at MotoIQ and this time it's a Nissan S13! If you watched our last video you saw why we think GK Tech makes the best front suspension/angle kit for the Nissan S-chassis. Now learn why we're equally impressed with their rear suspension upgrades to make your 240 competitive for both drifting and road racing!

Finally a well educated man not being some flashy youtuber with a bunch a guys just doing a bunch of whatever on cars, THANK YOU for this, I'm so sick of content that's full of gimmicks, non-sense, immaturity, and just pure zero substance

[@y.b.-]

The amount of knowledge Mike is giving out for free is jaw dropping honestly. So much value, not just for specific S builds but overall is awesome, thanks a lot!

[@worthamsgarage]

Please continue to make these S Chassis videos! Thank you so much for sharing you knowledge!!!!!

[@chris-lx5xw]

Wow this is great conten. Love the S chassis break downs! 👍🏻

[@albertt7784]

Another great video! A must watch video for any real fan of the Nissan S cars.

[@JC-vc7tf]

Thank you for the level of detail in this video, you don't know how much it's helped me!

[@funkyd04]

Love it when you dig in deep into The suspension geometry of different platforms. Please keep doing stuff like this!!!

[@JordanDunning]

Found the channel thanks to the HPA podcast. Looks like I'll be watching lots of your content, great stuff!

[@S-Kidz]

I'm already running some gk tech parts up front and they feel amazing. Know you convinced me I need more gk tech goodies for the rear now lol 😅 thanks man lol 🤣

[@BeamerFonz]

Man i love this dudes chill vibe and constant smiles, could watch him all day. Cant wait to grab this kit for my s13

[@slfrules1]

thanks for the great info! love y'all!

[@tommylyeah]

Wow. Props to GK Tech, that's really trick.

[@SeanOBryanZZ]

Thank you for another great video!

[@cherstonwarner2187]

Thanks for explaining the root cause of those car's wheel hop! I had been chasing for a solution in all the wrong places and hadn't considered it was a kinematic design issue.

[@RadDadisRad]

Wow. Amazing kit.

[@MK3504]

My s14 was my first car and sadly I neglected it a bit. I'm looking to restore it, thank you for these tips

[@tengrex]

Man this is awesome information. I have owned my 95 300zx for a couple years now. Its bonestock. And after watching this. I now know what suspension parts to upgrade too. Thank you

[@motoiq]

It really helps the Z32 because it has so much anti that it wheelhops like crazy and can't hook up.

[@RGHTBrainDesignDrive]

Siim out at GKTech is a fantastic suspension design engineer. Great content, Mike!

[@motary]

aww

[@Persocondes]

i Smashed that like button! shared and commented for the algorithm !

[@ronaldduff492]

Had to see what else you guys had after I seen the dual cam KA build. Gonna have to grab a 3rd ka before they shoot up in prices as well. I love what you guys are doing. Already have a GKTECH full front end and it’s amazing can’t wait to get some funds aside for the rear end setup. Gktech is a great brand and offer amazing customer support even make oem parts now

[@Cwrigh25]

How does it drive on the street? I don't drift but a lot of spirited driving.

[@ronaldduff492]

@@Cwrigh25 I like it but the coils I have currently are pretty firm.

[@factionmotorsports]

Mike is the man!

[@ryanvarner1522]

Can you put all your s13 stuff into one Playlist so it's easier to watch them all

[@brianspiess1420]

Please do a full s chassis video series!!! I’ve watch all the videos and ka video! Also a 1jz video from you would be cool. But regardless love the knowledge. I will be sending my ka to you guys for the honing and head tests you guys do!!

[@motoiq]

Coming soon!

[@hughdick1924]

One special feature of the camber arms you didn't mention is that they are designed to clear the chassis rail on very low vehicle's 😀

[@coupeL0VE]

[@C-M-E]

I almost find it ironically comical that the S13 chassis is in such demand the last few years that the aftermarket for it is producing kits like this in such good quality. I bought mine in 2002 for a whopping $2400 and had it 11 years til a kid in the neighborhood stole it for a joyride and plowed into a Lexus (found that out via a detective that showed up at my door while we were moving. Surprise!) Prior to that, I remember spending A Lot of time in junkyards scavenging Q45s and 300ZXs for 'upgrades'. Went through quite a few tie rods back then. 😉

[@taoisttiger4702]

Please do a more elaborate video on roll center/ squat geometries.

[@StrayzKid]

cool !

[@S-Kidz]

Geez Mike sure you aren't a salesman? Cuz the more videos I watch the more parts I wanna buy haha

[@Nighthawk745]

Great video, very informative, how would you rate this kit compared with Wisefab rear kit?

[@motoiq]

It is a lot stronger and has less toe steer.

[@deadlegintheface568]

Looks like a cool purple 280ZX in the background. Is there any where to have a look at it? Or could there be? Thanks for sharing your experience and expertise

[@motoiq]

It is a very nice car, belongs to a customer

[@anthonyconti1065]

Can you guys please do a video on how much it cost to build your r33 and rb engine please !!

[@TheKeatyBear]

They need to make this front and rear kit for the 350z chasis

[@motoiq]

They do!

[@luckduck5031]

More s chassis videos please

[@motoiq]

More coming!

[@shadowsaiyan]

So glad this information is being documented here, especially since the forums you could find this info are virtually dead now... #RIPZilvia

[@motoiq]

They are no more?!

[@shadowsaiyan]

@@motoiq It's still up ATM, but participation seems WAAAY down & it seems like there's been trouble keeping the site live for significant chucks of time a few times over the last year or two. Plus, so many dead Photobucket picture links. Sadly, that treasure trove won't be around forever, IMO 😫😭

[@cnknguyen]

Hi Mike.

[@waltermckinney606]

👍👍👍👍👍

[@yourmommashouse]

I love this video. PLEASE TELL ME THESE ARE AVAILABLE FOR S14 as well. And I didn’t know it came as 4 lug, I coulda sworn my s13 had 5 lugs. I know my 14 does lol

[@motoiq]

Yes they are.

[@jarrodnichols8111]

S13, S14, and S15 are virtually the same. Any differences can be eliminated by swapping the subframe.

[@josemendez-wu1nj]

I want to ask if you’re hiring so I can just be around you and gain knowledge and experience with in-depth explication on why you do whatever your doing

[@mjjjj_8780]

Gktech could be the best but they fall short on some details, can also be a pain in the az to deal with if you have an issue

[@motoiq]

We have not found any lack of details yet, especialy when compared to others we have used, even the most famous brand!

[@muasboy]

Super cool content!!! This is the guy that motor trend wants, but can’t have lol He can sales-pitch anything, without even trying haha

[@cruisecontrol6938]

See here is my thing,about 2 years ago I fabricated my S chassis ( s13) to accept the 2015 Q50 Akebono brake calipers & Rotors on all 4 corners. I had to weld the rear Q50 parking brake mount wholes shut, & match them to the s13 hub along with the anchor bolt hole. I used a G35 cable with some fabrication & I had to weld the anchor to the backing plate. It works but I can't use it for drifting because the plate is so thin. I have asked GK Tech if they have done the same thing & are working on a dual caliper setup for the 13.9 in rotor. I spied a video from Japan some guy in a G37 or late model G35 ( car was black) had dual caliper setup with Akebono's. I was wondering if I'm the only person in America who's done this or is there anyone working on a plan?

[@satanaz]

I want to buy a S chassis jsut to install one of those haha

[@hyper8545]

👍🤙

[@agustingerosa]

If those braces are so strong as you tell a hit will bend the subframe or chassis. I prefer bending braces than the chassis. The other thing is you dont mention what brand are those bearings because Enjuku doesnt make any bearings, they sell other brands.

[@motoiq]

Koyo bearings are used, are you talking about the subframe braces?

[@hazardlightsmotorsports]

Thank you Mike for the wealth of knowledge & it motivates me to rebuild my entire suspension! This is something I have always wanted to do with my S13 to do both grip & drift, which still has the original OEM hardware. But seeing how adjustable & durable these GK tech are I am definitely in the market to buy them. Also, as the only perfect place to do this in virtually on Gran Turismo to see this be done in real life is quite a feat! I hope that you can guys can do an installation, alignment, & final build video of your S13 project. I'm definitely going to get these because of the well thought out & engineered parts! If you have a link to these suspension parts or affiliation I would greatly appreciate it! Here is my S13 drifting virtually in Gran Turismo Sport. ->kzbin.info/www/bejne/bnaqiqWNftSEm5I

[@CRAZCHEVBOY]

wish this can work on me car :D

[@charlesescarria3726]

So you can use z32 hubs then? Right? And that's also going to allow you to use the beefier axles.

[@motoiq]

yes

PBM is the way for schassis rear

[@motoiq]

PBM is very good and so is this

[@ArchOfficial]

Some of the stuff about stock Schassis geo isn't quite correct. Schassis rear has toe-in bumpsteer standard. The reason it gets toe-out is because people only change the RUCA length without changing the FUCA as well. FUCA controls the bumpsteer curve. Not that any of this matters at all because elastokinematics mean you will always have 0.2deg toe-out or whatever under loads.

[@motoiq]

No we have plotted the toe curves many times.

[@ArchOfficial]

@@motoiq I checked my kinematic analysis and you're right, S13 does have a smidge of toe-out for the first 40mm. S14 is purely toe-in. Although in an idealized S13 geo the toe deflection is low enough to consider it as "none" for the first 40mm of compression.

[@motoiq]

Toe in was a nice side effect of reducing the anti on the 14 and 15

[@ArchOfficial]

@@motoiq I think the reason S13 had a mostly neutral curve is due to the focus on elastokinematic toe-in, at least when using standard components. The different toe curve on S14 is most likely just a side-effect like you said, but do you know if the elastokinematics were changed at all to compensate?

[@motoiq]

No I don't but I guess you could look at the bushings cutouts and guess.

[@thailandretromods]

My wallet is screaming watching this....

[@chewdoobautomotivedetailtm2883]

Man talks about S chassis like S12 never existed.... I was getting all hyped up for nothing

[@ddgsxr504]

Z32 rear brake rotor is NOT ventilated. Its a single disc thickness with the integrated parking brake.

[@motoiq]

They are ventilated, have one sitting right here and we own a Z32 Project car! Google pictures of Z32 rotors and you can see the vent right up the middle!

[@seethruhead7119]

No where near as pretty as the FDF Raceshop billet kit tho.

[@yourmommashouse]

Who needs that unless it’s a show car?

[@1gooey968]

it's also more than double the price.

[@motoiq]

FDF is painted silver so maybe it photos better but the construction quality is equivalent. I like the FDF adjustable offset tie rods and the fact that everything is in double shear. The GKTech has more adjustability particularly at the top due to the mount being under the tower, it can move all over that area in any direction. GKTech can use OEM configured parts due to stuff not being in double shear so there are tradeoffs.

[@Kiret123]

@@motoiq what is double shear?

[@motoiq]

@@Kiret123 the rod ends being supported on both sides, can be lighter and stronger for sure.
