Suspension Setup, Adjustments, and Testing 

"Remember kids, the only difference between screwing around and science is writing it down"

This was a fantastic video and deserves way more views. This channel is definitely doing the right things. You guys make it easy to bridge the gap from being just an auto enthusiast to an actually knowledgeable auto geek.

You guys are doing the lord's work.

This is so good and valuable - I can't believe I'm watching it for free. Wish you guys endless queue of students to your school. Thank you!

Love this channel. No clickbait, just great content with very well spoken teachers. I hope I can make the trip up to Team O'neal someday.

There's a wealth of knowledge in this video. Seriously thank you for taking the time to do this, can't explain how much it helps to have somewhat of a rule book when trying to figure out a good setup. This page deserves so much more attention.

This is the best video on suspension I've seen

6 years later still kicking.. Gonna be rewriting that whiteboard and stick it somewhere 😅 thanks 💪🏽💪🏽

This was an extremely informative video. Thank you. I don't even own a car, but I am probably going to use this for DiRT Rally. :)

Great video, thank you for including high speed and low speed! My KWs came with a guide that has one sentence to describe high and low speed compression so I never really understood how to set them up and was going to set them up as I would for a single adjustable compression but now I’ve made an excel sheet which copies your chart that gives me a guide to bring to track!

You guys inspired us to get into tuning our crosskart. All of you're videos have been a great lesson for us. Shout out for the whole team! Unfortunetly we live in Belgium and can not pick up a lesson at the school itself. But these video's allready have been a great help.

I LOVE these videos, I live in NH and have always wanted to spend a weekend at your school but unfortunately its a little out of my price range. I know these videos don't replace or compare to going to rally school but its the closest I can get and they're so informative and professional. Keep up the great work guys!

Wow! Thank you for sharing your knowledge. Great video! You just saved me a lot of time dialing in my first all purpose car. Thank you.

WOW! super helpful! Thanks. looking forward to the 5 day rally school next month :)

An advice I found on dampers from sim racers (rFactor 1 if I recall correctly)(sic): " There's basically four kinds of "bouncing": * One is where the damper are set too soft so that the springs start to oscillate. * The second is where the springrate is set too low and the car starts to bottom out either hitting the ground or hitting the limits of suspension travel. * The third bounce is where the springs and dampers are set too tight and the car start to hover over bumbs. * Fourth is when the car is transferring so much weight on front tires that the other tires start to lose their grip. This phenomenon is accentuated if the bounce happens only in the initial turning phase just before the apex when the load on the outside front tire is greatest. Inside wheels start to loose grip because of unloading, all the weight and need for grip is transferred to the outside wheel, the laws of physics steps in and the outside tire starts to slip; it looses grip, weight is transferred back to inside wheels, they loose grip and so on, the car starts twitching and skipping. Too low/high antiroll bar is the case combined with poor suspension settings. Rarest of them all since it needs a lot of variables combined for it to happen. It also feels mostly like twitching and sliding not bouncing. Also any combination of too tight springs on the rear/too soft on front combined with too tight rebound on rear/too soft bound on front, ie any kind extreme unbalance causes unpredictable behavior. Finding out what is the cause is not always easy... Experimentation and experience is the only key. Telemetry analyze with MoTec can help if you're able to read the info correctly. Bottoming is easiest to find, if you start to tighten the springs one click at a time the problem should go away. Oscillation can be found on the straights, if the car bounces a lot after it hits the bumb, tighten dampers. Hovering feels mostly like lo-grip conditions. EDIT: Oh yeah, one tip i got from a real life racer: if the car spins from the curbs (too high fast damping), lower rebound settings, both fast and slow. From my experience, start with the rear fast rebound. " Opinions appreciated

Fantastic explanation! You just managed to simplify what seemed to me like the most complex subject all my life. Thank you.🙏🏽

Thank you for the AMAZING vid and thorough instruction!!! This helps Immensely!!! I just purchased my first set of coilovers and can’t wait to test everything at my next track day!!!

You hit every nail on the head for so many situations! Lol make it adjustable comment never been more true. I am recommending this video in so many other channel's video comments section so I don't need a chapter to help out when people ask about what mods to do. Can't wait to get myself to your school to learn how to drive my cars faster and more importantly safer when I'm driving faster.

By far the best explanation on setup I've found to date. Thanks for sharing!

Fantastic explanations. Great knowledge and energy. Loved it. Thanks

Don’t think I’ve found many videos at all that talk about these adjustments. Been looking for videos about general under/oversteer guides. Thanks!

I took the screenshot but watched your explanation over and over. This is just gold👌 best video from you guys so far. Thank yoi

Liked the soup analogy, lol I took 4 pages of notes on this video to get the information in my head, and also as a point of reference. Very good video!

Cool now i know how to setup my Evo VI for that god awful Argentina stage in Dirt Rally 2.0 ;)

The detailing for the use of camber according to the terrain made me think how and what for the double wishbone suspensions work..! Love the content!! 13/10

Идеально разложил по полочкам! Столько полезной информации за 30 мин я ещё никогда не получал.

I've been around racing all my life and I knew most of this, but this is the best short explanation I've ever seen. Well done.

This is hands down the best description/explanation of tuning methodology for damper compression/extension I've ever seen. Grazie!

Wow, sick! I didn't think you guys were going to actually do it, thanks!

Great video! I'm surprised there isn't much views for it. This is right up there with Engineering explained.

This has been the most informative and useful video regarding suspension setup on a track car I've seen. Thank you so much for making this. This has helped my understanding greatly.

Just rebuild the whole back end of my wrx wagon, will defiantly be referring to this vid when sorting out the rear suspension. Thanks for your time and effort in this video! To the point and clear

Excellent - well put together in a simplified form. Thank you!

Great Basic advice explain in a way easy to understand. Brilliant Job. I loosing my way with multi adjustable suspensions and stuff now - but reminded me to keep simple! :) MANY THANKS

I was really happy to find I was doing the right stuff to my car under just pure suspension. This just cleared up my feelings and what I experienced when twicked cars but now I want to take a class on suspension geometry.... gonna have to add a class to my list now.

Easily one of your best videos. Super dense and useful information.

This is a damn excellent video and you are greatly appreciated, man

This is an amazing resource!! I hope I can visit your school one day! As to video suggestions, maybe some overviews of setting up a car's engine and powertrain for rally specifically and/or track use. Such as a general overview of what you need to build a basic/budget rally car. Keep up the good work, and I'll be sharing this with my buddies! -Cody

This videos are wonderful and really helpful, thanks for the hard work!

Very informative video. Thank you for taking the time to share this

Excellent video! Great work!

Since I've been playing carx rally, I've been looking for videos on suspension adjustments, and I found this one

Finding this in 2021. Wyatt is the man. Thanks for this

@Team O'Neil awesome instructional vid. you're a great teacher. wish i knew this before my 1st track event

Thank you so much. This is exactly what I wanted to understand what I need to do. Good that I had the right idea at least. Just nice to have the confirmation

Good video, I knew most of it but the order makes this a valuable tuning tool. They are right, this should have more views!

Thanks guys! The video really helps alot on high speed & low speed Compression/Rebound. Simple & easy to understand

Great explanation and chart, straight to the point. Thanks

best video on suspension setup that i've found. thank you!

Its video change my life. Thank you very much!

This combined with a handling/suspension tuning book, is perfect. I've wanted to complete my full suspension build for years but always had to put finances first. Maybe 2022 is the year I make the changes? I originally wanted a RallyX setup but I think a track setup with rough roads might be the better choice. The spring rates would be for smooth surfaces. This lets me have higher spring rates and therefore can keep my car low enough without bottoming out. I'm glad he mentioned a 1.5x increase in spring rates from factory. Very good advice for a starting point.

Wish this video was around when i started playing DiRT Rally... All of these settings are in the game, and i wasn't sure what half of them did exactly, so my setup was almost always out of whack.

Thanks for dropping all of this knowledge🤯

i feel like the vids on the channel like this are such a god-tier resource for people, and that maybe the car control eps and these types of eps should be mandatory viewing for anyone remotely interested in high performance driving or sim racing. i recommend them to so many people, they are so helpful ESPECIALLY for ppl just getting into this kind of stuff where it's like the holy grail of info.

I was just looking for a crash course like this one and this was so helpful and straight to the point! Thanks a lot!

You guys are fantastic. Very good at explaining things as they truly use at real life, not that tech teorethical analisis. Thanks for this.

Beeest guideline of all yt! On point explanation, funny, down to earth and simple for use! 👏👏👏

This is such an informative vid. Thank you for making it!

Best explanation I ever came across, brilliant stuff.

Thanks so much for this .. certainly will help my sim racing. Really appreciate this. 💯

Great info. You are awesome 😉👍 all what you say works😁 thanks , hope you will continue to share you knowledge

Excellent demonstration. Screenshot taken. I have a rally car RWD overpowered engine with a light butt that wants to oversteer way too easy. I will be trying these options thanks.

I was able to calm down to the point that I could visualize the dynamic suspension. I have seen the light! Thank you!

Always Gold my dude!!! Thanks

Superb explanation of car setup even for people unfamiliar with racing stuff.

Very informative. Thanks for the post. Especially rebound...I had the settings reversed, thanks for clarifying that.
