Suspension Design With GX550 Chief Engineer

[@96kylar]

Most youtubers just talk about new colors and bullshit with the new yota/lexus rigs coming out,..... Kai, gets it, and gives you what you actually want to hear about. Well done Kai.

[@floofy117]

That's because most youtubers decided to call themselves "auto journalists" just to make content for money on KZbin and aren't into most automotive things. Guys like Tinkerer actually spend time with cars as their hobbies/lifestyle

[@rickmontelongo4230]

KIAs are garbage you can’t compare it to Lexus or Toyota buddy are you that 😜

[@jean-pierrelutsheto6386]

@@rickmontelongo4230 You’re the crazy one since you failed to understand that Kai is the name of the guy in the video and not “ Kia the brand.” Read his sentence again 😂

[@mattb9664]

I unsubscribed from a major Toyota channel because he didn't want to respond to my comments about how the older GX appears way more luxurious than the new one...after begging for the "let me know what you guys think in the comments". (And I got sick of his bragging in every video about how he was going to change out his current Toyota again to the latest and greatest.) Those guys all thrive on providing neutral opinions in order to keep getting invited to manufacturer press events. They claim it's unbiased, but the invites influence their bias.

[@LyleTanner]

LOVE the fact you stopped the vehicle in the middle of the test track to measure articulation and then brought your own paper templates with magnets!

[@MHam1]

Very needy! Was Koji impressed? It’s no wonder you got 1-1 time with him. Nice job @Kai

[@nitrofreakmanho]

Agreed! He’s committed to the cause👍🏼. I’ve never seen anyone willing to do that under those circumstances. Kudos to Kai for the impressive videos he puts out.

[@ronaldrussell5481]

Like Kia said, "I'm nerdy!".

[@alexgavieres8293]

😅 When he whipped out the paper cutouts, I instantly thought...this is some next-level nerdiness happening!! LOL!!

[@vincefairleigh6899]

You should become an automotive journalist, I hate hearing about the interiors of trucks when a new truck comes out.. most if not all automotive journalists know nothing about suspension travel, so for the first time in a long time Toyota came out with something that isn’t just a crossover.. I’m still not convinced that this is a really capable truck, now if it came with 285-70-17” tires I’d be interested, keep those engineers on their toes😎

[@IndependenceOverland]

Thank you Toyota and Lexus for inviting someone who actually does this kind of stuff. A lot of the reviewers spend next to no time actually using these kinds of vehicles, and I always have to sift through their vague information to find the details that I actually care about. Invite some race enthusiasts to the sport car events, off road enthusiasts to your 4wd events, and someone with a family of 6 to your mini van events 🤣 Solid work as usual man!

[@TinkerersAdventure]

Thanks man! It almost won my heart from the trailhunter. But if the trailhunter would cost $65K, I'll probably get the overtrail lol

[@levikender4820]

I hope Toyota is watching your videos. They should be proud of their engineers and thankful for people like you Kai. You truly appreciate their systems and understand them better than most mechanics. Great video!

[@Tacoexplorer]

Probably most engineers as well!!

[@InGratitudeIam]

What an honor to be able to visit with the chief engineer of this vehicle! This shows that they have tremendous respect for your work. Congratulations, Kai!

[@chefgiovanni]

We love LEXUS, keep it up.

[@TheJmatagi]

I don’t think the engineers expected Tink. Your speciations show 24” flex I brought a measuring tape… haha Thanks for asking the hard questions.

[@monoped_adventures]

Everyone else "reviews" a vehicle. Kai "investigates" it. Great video.

[@ap-1994]

This guy is a REAL engineer. As an Mechanical Engineer myself I can say this guy is a cut above the rest.

[@RJ-vc2ju]

Then there's the other guy that puts automotive engineer in every title and limits his "engineering" analysis to measuring panel gaps and paint thickness lol!!! Well done Kai!

[@4WDisLife]

the BEST GX review on the internet!

[@CajunRunner4x4]

You are the only auto journalist on KZbin that has any real knowledge of vehicles. What a breath of fresh air. You are greatly appreciated sir.

[@floofy117]

"only" is a stretch. There's a literal automotive engineer that covers cars on his KZbin channel. I forget his name but he goes to car shows and events with his device that checks panel gaps😂

[@toyotatrailtrash]

This is why I waited years to get a bumper for my AWESOME FJ from Kai, it was designed and engineered! Thanks for the videos! So much info. To call you a KZbinr would be a disrespect to you!💪🏻💪🏻FJ4Life!

[@mattb9664]

I bet the Toyota Standard involves having each wheel in its own independent articulation stand, and then controlling the amount of Down and Up applied at each corner to achieve those numbers. So it's an ideal number that won't typically be achieved in the real world. Sound like the Toyota engineers were very respectful to make sure they didn't attack his method of measuring which was a real world measurement.

[@Ikki11235]

maybe the toyota standart is to measure it with some weights in the car simulating 4 Adults and stuff in the trunk? maybe even close to the max allowed weight to compress the suspension as far as possible.

[@geepuller1]

I love the templates and magnets. No wonder the head engineer had respect for you. Your videos are great. You are a dork in the best possible way.

[@DeuceDeuceBravo]

Brilliant stuff! We can always count on you to bring us the truly important nerdy details that the automotive "journalists" skip over. This platform looks pretty damn cool.

[@williamd8146]

Thanks, Kai! You present valuable information and analysis unavailable elsewhere. TA is my favorite KZbin channel!

[@dmb350]

I cannot express enough gratitude to you for these videos. You've made REALLY understanding suspension supported with actual data accessible to everyone. 100% the best channel on KZbin on this subject.

[@numbr17]

I agree. Best I have found yet. Kai is amazing.

[@brianpeck697]

Your channel is criminally underrated! Thank you for making such quality content

[@samro9744]

Wow! I'm pretty excited for the new Toyota trucks that are gonna come. This is superb journalism and you explain it flawlessly. Brilliant engineering on their new E-KDSS which I think will be safer and more effective than a true sway bar disconnect. Keep up the good work, Kai!

[@faheemabbas3965]

Well, the new LC250 pricing and MPG got posted today, and unfortunately, imo it’s a flop.

[@gregmgm06]

Your explanations are phenomenal. I went back and replayed a few section so I could understand better. Your comparison templates.....no one does that. So excellent!

[@GoodkatNW]

So the new Overland trim w/ ~9" of stock ground clearance and center/rear lockers is basically better (or at least equal) to a heavily modded 460? That's pretty damn cool that Lexus is spending so much effort in improving the offroad performance, knowing that very few 550 owners will actually take it somewhere where 19"+ of flex is even necessary

[@nitrofreakmanho]

You’re making some pretty amazing video Kai. Your explanations are top class! Your videos are helping so many of us understand suspension geometry and how all the parts work together better than most. Thank you for taking the time to test, document and explain all of the details that you share with us all. Keep up the great work!!👍🏼👍🏼

Kai, your videos rock! Been waiting to hear your take on the new GX 550 for a while now. You do such a great job explaining the science of off-roading. Can't believe Lexus/Toyota hasn't offered you an opportunity to join their team yet... Keep it up and thank you for helping me solidify my decision to buy an Overtrail this year!

[@joegenshlea6827]

Well articulated!! haha. BEST BEST BEST review of the GX 550! And I've watched just about every one of them. You filled in the gaps that all were missing. Seems like an awkward conversation though with the Toyota Engineers.

Another amazing video Kai! Love your attention to detail and how passionate you are about this stuff. We appreciate you being nerdy! Turns out, lots of us are the same way haha.

[@TinkerersAdventure]

Thanks Grant!

[@PatrickRich]

This was great. I got all the answers I couldn't get at the time. I still think its a crime that eKDSS is not an option on the Land Cruiser 250. The main benefit I noticed was how incredibly level the body stayed in all terrain. no head toss, I was amazing. Then you can rip into a corner and not roll like a boat because its automatic. I was very impressed.

Kai, your channel is fast becoming my favorite content on KZbin! I really appreciate your approach to testing and reviewing off-road vehicles and suspension systems. Most reviews I watch are a waste of time to try to find any useful information. Your videos I rewatch several times to understand the concepts you present. Keep up the outstanding work! Thank you!

[@marcoallasio7790]

I don't even have the money to buy an offroader, nor the lexus is sold in Italy, but here am I, looking at technical reviews just to enjoy your videos. 🤣 You are great Kay!

[@aarongerman7857]

This. Is. the best review of the new GX550 hands down. Full stop. actual information. there's 50 reviews that tell me about the tow rating and v6 turbo. You have added an enormous amount of value for us who really want to know about this thing. THANK YOU

I'm glad to see how respectful you were to be honored in the presence of the designer. You were able to gather much data while also being dignified. I'm sure he appreciated it. I know I do! I also like how you came prepared with templates and magnets, and really got into the weeds with your inspections. This is great information. I wish other channels would pay attention. Then maybe "the KZbins" would start to be what they truly should be. You're doing it right. Keep it up, sir.

[@Unb3arablePain]

I miss the V8 but this is excellent news to see as a GX460 owner and fan! Toyota went above & beyond not just to improve the interior or ride comfot but made large changes to the mechanical design od the suspension itself to make the vehicle even better for off-road use. That's good news, I think many believed they'd try to make it more mall crawler friendly only.

Pure gold in terms of information. Good work. Clear concise, well prepared, you know what you want to look for. Keep it up!

[@WhiteyNorge]

Toyota tend to engineer their closed lengths to be coincident with 100% bumpstop compression, or metal-metal with bumpstop removed. The extra 4 inches or so the Lexus engineer refers to may be the remaining bump travel from bumpstop contact to full closed on the struts and shocks. The GX550 is also using the 300 Series chassis which is just a modified 200 chassis, so travel is different to the older 120/150 chassis.

[@tonymartucci7097]
