Coilovers - Explained
ฝัง
- เผยแพร่เมื่อ 25 ก.ค. 2024
- What are coilovers? How do coilovers work? Coilovers are a common performance upgrade for car suspensions. Coilovers can allow for lowering a vehicle, and also can reduce body roll with stiffer springs. A coilover gets its name from simply a coil spring over a shock absorber. The coilovers used in the video are Yonaka Motorsports coilovers for a 94-01 Acura Integra.

NEW VIDEO EVERY WEDNESDAY! - ยานยนต์และพาหนะ
All of your videos pack tons of relevant information, clearly and consicely explained, at a great pace without ever making me feel overloaded or confused. You are simply the best! Thanks for all the lessons!
Kirill Melamed Glad you enjoy the videos, thanks for watching many of them!
+Engineering Explained isnt the ford raptor have coilovers? couldnt increase height in any way ?
Making rookie mechanics less stressed.
@@EngineeringExplained hey there brother. I have a Toyota Camry 2015. And can suggest a good suspension for a smooth ride and non bumpy. Thanks
The problem with lowering springs on stock shocks is you reduce useable shock travel, so your shocks could potentially bottom out. Also, the dampening rates of the shocks may not match the spring rates of the springs, so it may cause an overly bouncy ride.
They do not pay me to do reviews, they simply provide me with material in order to enhance my videos. It's much better when I can have the actual item when explaining something. They've been very generous in helping out, and I appreciate it quite a bit. Doesn't hurt that I get to use some of these parts on my car! :)
He makes so much effort on every video. #respect
Ahmad Hasif or maybe he isn’t, some people are just really good at this stuff
You are the only one that makes videos that I can understand. Thank you.
all thumbs up!
Totally thought you were wearing a beanie for the first minute.
lmao
Yea, 6 yrs ago was a strange look hahaha
Zack Klapman lol I literally was going to write that!!!!!!!
I thought it was Dimitri Martin
boyddustin this scenario happens on TH-cam waaaay to often 🤣 I like how there’s other who think alike.
Thanks, yes there are definitely additional factors which need to be altered to maintain an ideal geometry of the suspension. I do hope to make a few videos on ride height, cg, and roll centers to expand on this. Eventually :)
Yes, I'll have install videos soon.
Great Channel, I'm a gear head and I've been around cars for 20+yrs. I understand about 95% of all your topics before watching, but it's always good to review and refresh. I appreciate what you do for the other viewers. PS I would suggest a companion video to this explaining adjustable suspension arms and upgrading bushings, as these are a must have to maintain proper geometry after altering ride height. Keep up the informative and unbiased work!!
Great videos here. You manage to keep them short, but still informative and simple enough to where most anyone could make sense of it. Definitely a real help.
Yep, and yep. I have a few videos on the installation, and one on testing them as well. Cheers.
So far Yonaka has been a great partner in helping make these videos. My relationship with Redline360 is growing as well, which has great potential.
Just installed them this past weekend. Quite noticeably stiffer. Ride quality suffers a little but it does seem to stay very flat in corners. I'll need to get some upper control arms to take care of the negative camber, I've lowered it a good amount.
Hoping to get them installed this weekend!
MacPherson strut is a type or variant of a suspension. A coilover can replace the spring/strut combo already in place in the MacPherson strut setup.
MacPherson strut is basically a type of suspension, I have a video on the topic. A coilover can be used in various suspension types.
They seem to be pretty good quality. I have not yet installed them, and plan on doing so hopefully this weekend. Initial impression though they seem good, and the spring rates are in line with other aftermarket manufacturers.
Thank you! Glad to hear.
Yes, many do this, but it does alter the pre-load of the spring.
I will have videos of the install, and hopefully a test video as well.
Correct, depending on the suspension (double wishbone, macpherson, etc.) the top of the coilover will have a different mounting. A MacPherson strut will likely have a 3rd screw on top.
The cheapest option is lowering springs, but there are reasons you don't want to do this. It won't allow for the full travel of your shock (likely) if you do this, where as coilovers will allow for lowering without altering suspension travel (of the included shock, not all do this, but most do). Also, to get things done right, you may have to get an alignment to alter your camber and toe to make up for the change in geometry.
If you plan on lowering your car, and don't have adjustable camber, it's a good idea to get one to prevent uneven tire wear, or if you want the ability to adjust it for track use.
this was his first video i understood properly. i will have to rewatch some as my interest in fixing more stuff on my car increases. good video and have subscribed.
Thanks for subscribing!
Dude, your videos are quickly becoming some of my favorite
After reading some of the comments their seems to be some confusion with the term "coilover". There's basically two different meanings when people generally refer to coilovers. When people typically refer to coilovers (as in this video) they are usually referring to aftermarket coilovers that are performance-oriented and are usually adjustable in both ride height and shock stiffness. The shock/strut & coil spring are integrated into one assembly where the coil spring is seated over the shock/strut, hence the term "coilovers".
However, most vehicles that have Macpherson strut front-suspension design use an OEM strut & spring assembly where the strut and the coil spring are integrated together into one unit, so technically they can be considered a coilover, but they are OEM or OEM-equivalent and are not adjustable. They are also primarily designed for ride comfort over handling performance as opposed to aftermarket coilovers that are performance-oriented and designed for handling over ride comfort. Hopefully that clears up some of the confusion.
thanks! i commented before i read this.
Thank you and yes it does
Learning about suspension systems as I learn to do work on my own vehicles. This video is super helpful and easy to follow. Thank you!
Glad it was helpful!
I'll probably get around to a sway bar eventually. I'll likely try to go with the Type-R set-up.
Great video, thank you. I would love to see a video on what makes Ohlins better than the competition. From what I have experienced, there are no compromises with that coilover system. Plus you might score some very nice dampers for your STI by reaching out to them
The spec1 may simply mean that the damping is not adjustable. Though I have not yet installed mine, the build quality looks to be good. I need to install mine!
The way you explained things are so easy to understand. IF only others can explain things as well as you do. Thank you!
You need to become a teacher or run your own engineering shop and design race car man, no joke.
Beast60 What about a TH-cam channel dedicated to educating people about cars?
Engineering Explained haha that too, but does it pay good?
Engineering Explained or why not both?
@John Matthew 🤣
Engineering Explained go on a quest to build the perfect super fun “single guy” enthusiast build. Such as a Nissan 240 or similar
Eventually, hopefully, yes. I'd like to get into CG and roll center.
We're all happy, things are going well!
Wow. Look how young Jason was here! I’ve learned much from his videos over the years. I’m glad he stayed with it!
Good ole' Mohr's circle. Perhaps one day, I'm trying to keep most videos automotive related, but perhaps if I got into chassis stresses or something of the like.
What did you not understand? I have a suspensions playlist that goes into much greater detail of many of the topics.
I love your videos! I have a question. If I want the smoothest ride on my daily driver, what kind of suspension modifications would be best? I switched to summer tires which helped a lot, but my favorite is actually the "boat" kind of feeling some luxury cars have.
Hopefully I'll have a video up at some point.
That's what this video's about. Check out my other suspension videos if interested.
Check out my video "suspensions - explained" for detailed answer. It dissipates the energy absorbed by the springs when they are loaded (from bumps, turning, accelerating, braking, etc.).
Eventually I could make a video on this, yes. It's a good topic but also gets very complicated very quickly.
They may fit, but that doesn't necessarily mean the damping and spring rates are properly matched, or that you won't break the shocks on a heavy bump. Unless they're simply an OEM replacement, with the same height.
Really really good at explaining things and good diagrams. Keep it up man !
Thank you sir, Glad to see that someone else sees sense in this conversation!
Thanks!
Absolutely.
I'll get around to it at some point, yes.
99 Integra GS, I've got a more detailed answer to that question on my FAQ, which you can find on the "about" link on my channel.
If you increase spring rate, you will need to adjust your rebound and compression in the shock. If you are going from a soft spring, your compression will be to stiff and your rebound will be to fast for the stiffer spring. The proper spring rate should be vehicle weight plus passenger weight and spring accordingly. Then revalve the shock to slow or speed up movement of the spring for the compression or rebound, to your needs. Be careful to not preload the spring to much or you might coil bind the suspension.
Pre-loading the springs does not change the stiffness of the springs. Unfortunately if you want stiff you'd need different springs. That said, you may be able to achieve what you want to do cheaper with anti-roll bars, not really sure what your goal is though.
Thank you man this really helped with my 2.4l taco
I don't plan on dropping it 4 inches, maybe 1" at the most. I live in a city where a lowered car is incredibly impractical. Once this is my "track-only" car I'll go a little more, depending on if I can get the suspension geometry correct.
Super informative, thank you! :) But I still can't get myself to get it done, fearing of potholes and bumps along the road and highway, especially at my place here
Yes, but by using stiffer springs you aren't reducing the "independence" of the suspension. Sway bars act as a link for the two, but are a cheaper solution to the problem of body roll.
+Engineering Explained, I could have used those on my 89 Mustang to stiffen my weak rear leaf springs. Great Explanation. Keep up the good work.
no u could not...mustangs after 1978 don't have leaf springs
Great video man,that was classy and knowledgeable, keep them comming. Greetings from Costa Rica, central america
I still watch these videos from SEVEN YEARS AGO. Lol it's crazy to think about it like that but I love love love these videos. So informative and precise
Really great exploitation! Helped me out a lot.
thanks mate you re the best! keep those vids coming!!! i've learned so many things
ty, im not knowledgable on cars but you r explaining very well
Dude, awesome video man. It's crazy how much I have learned on this channel, and how it conceptually helps with physics (Which I'm taking now!) Also, I think you should do a walk around of your Integra soon! Perhaps after you install these coilovers, best of luck and don't stop making videos!
It could be that the fluid, or some of it, has managed to break a seal and leaked out, thus making the shock absorbers of no use.
Depends if there is anything else that is powered by that belt.
Check out my video "suspensions - explained." Damping comes from the shock absorber.
Thanks a lot dude! Really thorough explanation.
Amazing explanation, keep it up man.
Most accurate descriptions.. appreciate the videos and info
I'll never forget I had an old RWD Malibu with sacked springs in the rear that I did not want to pay to make new again so I asked about coil over shocks (since it was also ready for shocks anyway) and the first couple service writer/mechanics were like"huh?" basically claiming I had no such option ...So finally I just went to aftermarket parts counter and ordered a pair of coil over rear shocks ....peanuts $ compared to doing it "right" ...It TOTALLY corrected the problem, Worked perfect! I was very happy ...never did understand service writers claiming there was no such fix....wth??
Great job. You are very easy to understand and pleasant. Subbed.
Luckily I haven't had too much go wrong with it. I certainly don't do everything. I've just replaced the distributor cap and thermostat. I've taken it to the shop to fix oil leaks/burning, but I think what truly needs to happen is a full engine rebuild.
That's awesome man. Keep up the good work!
Nice vid. pretty thorough. Got my Skunk 2 pro S2's going on my 8th gen Si tomorrow. They are known for being a bit harsh as far as coilovers so I think I'm going to try and keep the spring pre-load to a minimum. :)
I've been researching what spring rates would be ideal for my driving habits. I am getting the BC Racing Coilovers extreme drop with front and rear cup kit. The issue i'm stuck on is what spring rate to choose. This video has been most helpful in learning about coilover sysytem. Thanks. I'm still trying to figure out the spring rates as with BC they are custom and can do any spring rate you choose.
Great video. I am in line to know more info about how these coilovers work for you. I've been going back and forth on wanting to pick a set up but there isn't too much info on these.
Man this videos are sooooo informative, its so easy to understand, it doesnt even matter the fact that english is not my native language. I really apreciate the fact that you take the time to share your knowledge. Ive learned a lot from you, Im a ver happy subscriber, always waiting for new videos. Greetings from El Salvador :)
Yes, eventually.
good work, could you explain the suspension for a 4x4 SUV which may use a soft sring and other suspension components; also if one wants to raise the vehicle instead of lowering what suspension components does one use, longer springs, please make a video on that, thank you.
You make my life so much easier!
I'm designing vehicles for a video game and was wondering how to improve the payload/suspension. Thanks for the cool video!
Thanks very much for this mate. I had never heard the term until about twenty minutes ago, googled it and got your video. Brilliant!
The only think I don't undersand is why you need coil springs AND the oil cartridge shock absorber. Is that solely for controlling the damping? I am a motorcyclist where we use cartridges up front and a coil at the back - possibly with a small sealed shock inside that.
Excellent video
Excellent Explanation !!!! Thank you
That science talk at the end blew my mind🤯
First of all, thanks for all the great information you're putting out there. Being a mechanic I've found it to all be correct so far. One question though, I have a bmw z3 1.8 1996 with a 50/50 weight distribution, should I use the same spring weights then? Thanks!!
Thanks again for the great explanation
could watch hours of your videos! learned so much! Would you mind explaining "Bags" airsuspension, are they viable for tracking your car, etc...?
Wow nicely done, I enjoy your video.
@engineering explained . how about a video on Subaru suspension. my front struts are blown trying to figure out what springs and struts, or coil overs I should go with.
Perfect Explanation! Thanks!
Awesome video brother. I was thinking about getting coilovers without new shocks, but going with my stock shocks and buying new shocks at a later date since the whole package makes it twice as much as just the coilovers. How long would you say it is alright to ride with coilovers without new shocks before buying them? Would it be better to just wait a longer while and buy the whole package? Thanks!
Awesome explanation!
I first saw this video 7 years ago. And now I’m experienced and smart enough to fully understand this now.
bro i love your videos and i learn a lot from them :)
i have a question if anyone can answer it please! are struts and coilovers the same thing?
Can u suggest which is the best type of shock absorber..like hydraulic or gas filled?..or else what could be with comparision of their costs too.
"And that of course being 9.81 meters per second" 😆👍
After watching your videos I always think... I need to brush up on my arithmetic!
Thanks for the info.. Excellent!
I am a car idiot. In the words uttered to John Snow, i know nothing.
When forums keep mentioning things like this... i keep seeing them fly right over my head. This explained them clear and concisely and in plain english. Awesome. Thanks.
I like your videos and the way you explain things so even dummies like me can understand it. 👍
You explained this very well.. thanks for the information
Great video. Like what You do. Keep it up!
