Yonaka Coilover Test and Review - Acura Integra
Вставка
- Опубліковано 2 жов 2024
- A test and review of Yonaka Coilovers on an Acura Integra. Demonstrations of body roll and nose dive. 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!
this is a difficult mod to explain to the girlfriend. Honey I'm going to lower my car. wife: sure okay why? me: it looks better. wife: how much? me: about a grand plus labor. wife: okaaaaay. will it drive better? me: wehhlllll.... it will be a lot less comfortable and the ride will be stiffer. but it will look great and handle a bit better :) wife: so you're spending 1500 dollars so that you can't go over speed bumps and you'll have a stiffer, more uncomfortable ride.... me: ummmmmm.. wife: no
The price to be a fanboy 1500$$$. Learning how to work on a car yourself and not having to ask your girlfriend how to use a tire iron to take the wheel off "PRICELESS"
That’s why you dont marry your mom
Jamaican Me Crazy just dont tell the wife
Jamaican Me Crazy im curious as to why the hell you are paying to install coilovers instead of doing it yourself.
Happy wife happy life 🤡🤡🤡
Your Acura is always scared and makes a face like this D:
haha it hates new tests

Just a GS, unfortunately. No vtec. :( But I still love it.
Body roll is the result of load transfer when there is compliance in the suspension (e.g. it's on springs).
Load transfer is a result of forces on the tires acting like a lever through the car's centre of mass. When the car is braking, there will be a force pushing backwards. This force isn't acting directly through the CoM and this causes the body to nose dive, and the weight force on the front wheels to increase, rears decrease. Even completely rigid vehicles are affected by load transfer.
Well the springs are stiffer so you the car won't compress as much with weight as stock springs. That said I'm yet to have my trunk fully loaded with them on yet. I'd like to raise the back up just a touch.
Thanks, glad to hear it!
I wouldn't say it really feels much different, but it doesn't dip as much as previously, the body just stays a little more flat. I did not test the actual braking distance though (and conditions were different for the two videos).
Spring rate went from around 3-4 kg to 12 kg in the front, 6 kg in the back. I believe the driver was also driving a bit more aggressively in with the coils on to compensate for less body roll felt (but the speeds should be fairly close).
Engineering Explained how are they holding up do the shocks still work?
I'd like to have a little more height in the back, it sits pretty low. No problems yet, though they've only been on for a about a month.
My accord was sitting low in back so I threw accord hybrid strut assemblies in back!
Wow, with this suspension mod you end up using more of the available grip of the tires. When you brake after the mod the tires screech a bit; you get to the limit sooner. My Lincoln Ls is sporty, but when you turn quickly _without_ braking (loading the front springs) the car leans like hell. I totally need to get some coilovers.
i guess my car has stiff suspension cus its a bumpy ride lol. but good to know. I recently got a 04 civic and i'm trying to learn about my car and what can or needs to be done with it. thanks for the awesome videos! its my go-to to learn about cars and how to modify them, I'm a noob. lol
If I remember, the 7th gen civics and such have a stiff chassis. I have a 2003 honda civic which is funny but it is pretty stiff just from the factory. This is what causes a rather harsher ride and more feeling for smaller bumps and etc.
how come with the new coilovers when you brake there is a loud grind?
Sounded like the rear wheels locked up.
that would be wheel slip sounds like a bad thing but not 100% see factory suspension in the video shows more of a bounce motion which to my knowledge cuts down on the ammount of force put to the front make it more of a comfort not shot into your steering wheel braking method great for taking kids mother dogs etc to different places and you had to hit your brakes hard because someone cut you off or because something or someone ran infront of you now as far as coilovers lowering springs etc with higher spring rates these forces are put forward or to the rear or sides in an opposing force or collective force meaning itll either balance the force or move the force to one area the reason for the wheel slip is because more force is moved to the front of the car causing more traction but in return the driver is use to the stock suspension and is applying to much brake to the car to stop that quick to show that their is barely any movement to the nose of the car now lowering whichever way you pick will affect braking acceleration nose dive and squat squat is shown in acceleration were the car moves weight to the rear wheels shown more in rear wheel drive vehicles ever watch drag cars? Notice the big rear tire small front tire set ups and they do a wheelie well its because the force is moved to the rear and the torque mixed with the squat makes the car act as if you filled it full of concrete hope this helps you!
+xxxMIGHTYDIPPERxxx long ass run on sentence but provided a smart answer thank you sir I appreciate the knowledge that you are giving to others especially me because I don't know too much about this stuff but thanks to people like you and the person that created this video I am able to continue my journey of learninh and also gonna think about putting these in my 2011 Acura TSX maybe drop two inches and make it really firm
+Tristan Brown haha my bad! But glad i could help out goodluck!
no sweat Vapenasty I appreciate you fam
That Integra is in really nice shape bro. I love it :)
Well, two different drivers, different brake pressure, and cold weather w/ the Yonakas. Notice they actually locked up unlike when it was warm.
Well produced and informative, thanks.
I am yet to scrape anything.
It was a pretty easy installation, and they're not too expensive.
Great multiple video series by EE and illustrative comment thread here for anyone considering changing from stock, or selecting factory option packages on their new car, based on drive style and road conditions. I've been reading and driving for 45 yrs and learned lots here. The harmonic frequency response of the driver increases with age, IMO, so old farts on bumpy roads may need the softer factory suspension for everyday. Maybe use a factory or aftermarket adjustable package for performance driving when we don't need the dampening to save our face from vibrating off!
I see the importance of a track tested, time tested aftermarket system over a multibrand piecemeal approach is implied by your analysis in the other videos.
Appreciate your systems and analytical approach to suspension mods!
Thanks!
That's a good question. I need to install a camber kit to get rid of the negative camber caused by lowering it. Sway bars are a possibility. Once I have another car I'll strip this one down, and get to the engine mods.
Did you remove the ABS? If it's on it's probably not functioning, so you may want to get it serviced.
Yeah it locked for a second and then the ABS kicked in.
Can you post the spring rates before (stock) and later (Yonaka) please?
Not painful, but I go much slower over them (unless they're the wider type).
Would you recommend these to others? I'm thinking for buying a set for my 02 wrx but i wanted to make sure you approve of them first. I trust your opinion. This is my DD, with spirited driving and the occasional autox.
So I know this is an older video, but I was wondering what your final set up was like with your coil overs? I'm looking at putting coil overs on my 2011 WRX, I love on an island with really twisty bumpy roads, so I'm not stoked about the idea of creating a low and harsh ride, I just want to have better damping than stock suspension when I go over these phantom bumps that jolt the car skyward mid corner. hmm, still learning about suspension set ups and tuning. looking for some advice.
Front strut bar, but this will not affect body roll (extremely minimal).
The spring rate is what causes the difference you've seen. Stiffer springs means the body rolls/dips less. THe dampening is all happening behind the scenes, the result of which is a car that does not bounce (but absorbs the energy smoothly).
'Merica!
It was much colder outside, and I slammed the brakes causing ABS to turn on. As long as the brakes are strong enough, any car can lock the wheels (ABS will kick in to stop this). This isn't a result of the coils, but you are correct in that high spring rates can cause the car to lose traction if the surface conditions are rough.
Ha! If only I could get my hands on one.
Holy shit that was awesome, highly considering coilovers now
that made a huge difference. did you get these on the amazon special right now? im thinking about ordering a set for my miata. price would be $500
It was a cold day and I went straight to the braking video so the tires were cold as well.
Remember when EE used to be cool and do motorsport things? I do..
Pepperidge Farm remembers
Nice video unfortunately we don't see such comparisons on other videos
are your tires low profile as well,
suspension + low profile tires + chassis supports are good
and your car is light with a short wheel base, could corner like a flea
Stock size wheels and tires.
Why is it important to reduce body roll or rather, for what purpose?
Great question, and I was actually hoping to get into that with some videos but never got around to it. Basically the flatter your car stays, the better the tire contact patch as the alignment of your wheels doesn't change.
And also it reduces inertia force side to side which stabilizes the car and makes it handles better!
Depending on your coilover setup, you can setup each coils with specific weight tuning to help into corners even better, also here is a very very rough/estimate numbers you might see on a figure 8
Stock coils = 12.5 with lateral G's of .92
Upgraded coils = 11.0 with lateral G's of 1.01
How about nose lift during hard acceleration? Or does helf keep the front wheels on the ground.
djay102687 Less noticeable with the coilovers, but I don't have any recorded results.
djay102687 looking for some too let me know if you find something good with less lift during street drag launch and no back squat so far PROGRESS CSII CS2 COILOVERS and KSport® - Race Version Coilover Kit
dont know what to go with
Absolutely! Patience though, they're not going to be here for a while. :)
Fun, reliable, light, hatch. I admire light cars, and hatchbacks, above nearly everything else. And two doors.
Fuark man!!! That stare you do at the start freaks me out....
Dont listen to the subaru fan....I wish you didnt have the honda to but id say buy any nissan, toyota, mazda or manual mistubishi before a subaru. Even tho a early nineties nissan will be full of rust id still buy it before a honda or subaru
They send me the products for use in these educational videos. :)
Why it looked like girl driving your car?
Easy now!
Yes, it is easier to tell in the videos.
You should make videos of you modifying the car :)
That's the plan! I have videos for the coilover install.
Haha "cleanest you've seen." You'll take that back after Wednesday's video. :)
Excellent video! As expected from you though all your vids are super pro 👌🏽
That bounce after the stop with coilovers tho...underdampened?
One thing that some people might miss out (even from an old video like this); body roll tends to "accumulate" or pile up upon consecutive hard turns.
Swerving creates the same momentum as rocking and even with good coilovers it will create some significant body roll in the end.
Just stating this because there are people where I'm from who swears that their coilovers are perfect and willing to take rapid turns as hard as they want and then blame it on something else when they spin or crash their car.
Yonakas have slightly stiffer spring rates....thats why they "handle" better. The lower you drop, the stiffer you need your springs !
Hopefully more videos on these topics in time!
Both UTI, and WyoTech are more into the money that you pay them then getting you a good education, But with that said, It's what you put into it. Just remember that school don't teach you everything and once you land a automotive job in a shop, learn from the guys/girls that have been there a long time. School is mostly a background knowledge of how car's operate. Your real learning will come from a shop. Oh and buying tools...buy the best you can afford.
thanks for doing a side-by-side, it's nice to actually see it instead of just knowing what it does
Hey , great video thanks.......I have a mint condition 1997 Honda prelude that I bought brand new with just 23,000 original miles on the odometer as of today.....Would like to lower it with coil overs........How ever it's a job I would prefer a Honda tech at a dealer do, any idea how long this may take for the change over ?......Thanks , hope to hear back from you Engineering
Awesome!
Sorry i got so caught up watching one after another that i often forget to like your videos. ill make sure to rewatch them and add the like when i make it back aroudn the loop. I used to be cartarded completely beyond repair; But im great with computers so technically i could learn, just NEVER found a knowledgeable or willing party like yourself. Kudos. if you ever want a website made or anyone to work with you let me know.
Did you have to go thru getting the car all re- aligned after you installed the coilovers or did you do them where you install them almost exacty the same as where thstock 1s were positioned to not have to get an alignment after so its all balanced out?????
you have to get an alignment only way it is possible is if tbe car is say lowered 2inches you buy new suspension and set it for 2 inches any more or less will hurt the alignment which on hondas specially older ones is usually the toe
Why Chuck Norris? You don't need coilovers... Just ask the car to be lower, I'm sure it will comply
what engineering are you studying and what level are you in because you know much !!! i am engineering student also in my senior year but i dont know half of the video you have..lol
Why do you want to raise them? I want my fender to be aligned to my wheel not tucking my wheel but just above. Do you recommenx me these? Have you had any problems yet?
im looking to purchase the yonaka coilovers for my 95 acura integra. honestly just wondering if its worth the money spent, for whats all out there? Are they honestly a good set of coilovers for the integra? my teggys just a daily driver. so im looking for more comfortable driving.
So you are saying I should put coilovers on a Reliant Robin to prevent me from tipping over while turning at high speeds? :D I'm gonna try that right now!
what everyone else said and also you get a better idea of what the car is doing, less of that numb feeling you get from a comfort tuned suspension.
+ Engineering explained Im looking to do some back road and regular commuting with this set up, how's it holding up? should be about a year since you release this vid?
I read bad reviews about these coilovers, what is your opinion on them, i heard they arent very adjustable as yonaka says? please let me know you thoughts on them for the price.
Thanks, glad you enjoyed!
Great video, but I'm having the Pandora's Box dilemma after installing coil-overs on my GSR. The Coil-overs lower the car about 1.2". This changed the camber in front and the toe in the rear - both of which are non-adjustable from the factory. Adjustable compensator links for the rear and adjustable upper ball joints in the front are required - at no small expense.
Whats that sound while braking with the coilovers? Did you lock your wheel for a moment or did it hit the wheel arch?
looks like the stopping distance was increased with the coilovers though
How many inches is the your car lowered. I want my integra lowered the same exact height. Not slammed but a clean drop like yours.
Got mine ordered can't wait to recieve them
Love it! Thanks.
don't troll me or anything but... What i've learned from gran turismo is that with low suspension and high spring rate allows the car lose traction and slide more when braking or cornering. In your braking demo i even heard the tires skid with the yonaka.
Doesn't look like the body roll has changed much in corners, based on the side-by-side pictures.
so would you recommend these, are they worth the money. its mostly to lower the car and I wont be driving to get bodyroll or hard braking
What's the use of no body roll? I know ,better handling, but how so? Please reply guys thx.
let me guess, you inserted a key into the ignition and turned it to start?... just go away
It looks like it coincided with a wet patch on the ground, I'd say very slight lock-up
Did you put them in or have someone do it?
I did it, was fairly straight-forward, I have an install video if you're interested.
Engineering Explained
I'll watch it. I've done them before but I dont have air tools or a lift like I did last time. I'll be lowering my 98 civic last time it was a 96, but like I said I had air tools and a lift. I'll watch the video and see how you did it on the ground! Thanks!
Yeah, it was all done with just floor jacks and socket wrenches. Takes longer, but it's much cheaper to do.
Nice video, my tercel has coilvers and they are quite stiff, and non adjustable. Does your car scrape with them? My 3 inch turboback was poorly installed and scrapes.
less body roll mean there is more tyre contact with the road giving better grip
Would you recommend these? i as well have a 99 integra looking to buy some coilvers.
If you're simply looking to lower your car/stiffen your springs, they definitely do the trick. Mine are still holding up, and they're reasonably priced.
the braking nose dive seem take more time to stop in the yonaka. why is that?
I like how much effort you put in to something so simple. Keep it up man!
Hi! I just installed my new coilovers. I've been doin some research about bouncy and ucomfortable ride that it gives. Even if I set it up to the stiffest settings it still feels like driving with an oval shape wheel, I know you might say get a wheel alignment but I already did, even had a wheel balance. Could someone explain this to me? Is it the road that I'm feeling when I'm driving or is it just the coilovers?
BTW. It's a BC V1 Coilovers. I know this isnt the perfect place to ask this but ye.
HiatusMobs that oval shaped feeling is understeer. get some stiffer sway bars in the rear to get a bit more oversteer.
Yonaka tuned for sport. Stock tuned for comfort.
With Coilovers + Sway Bars you will see much much of an improvement... im currently running my car with performance (customized) Springs only and fully bared up (sways, tower braces) and it drives awesome... Coilovers are definetly the next mod along with a short throw shifter... Subscribe for updates maybe?
Is it painful when going over speedbumps now?
I always wondered, why an Integra? I mean Integra's are great cars but you could have gotten a faster car with a turbo for the same price, Just wondering. P.S you make excellent videos keep them up(:
or just take the cluster out and remove the ABS bulb , thats what I did with no problems when I deleted my abs on my car
Your steering wheel is on the wrong side ;)
I'm looking into some good price coilovers and ran into these . Whats the feed back? I need something that can hold weight I have a 95 honda civic and even my stock suspension at stock height rubs into my fender with weight on the back.
I'm planning to lower my car also!
Damn you can really see the amount of reduced body roll and the stiffness of the front end while braking. You could hear the tires skid from braking after the coilovers were installed. Not a bad modification for $575. You can hit those turns above 1st gear now!
Skid was due to ABS and cold weather, but it did have less nose dive.
What state or general area do you live in? Been curious for a while.
how do you like your yonaka coilovers so far im looking to by a set and i really need to knw asap lol please and thank you
They're fun, the car feels a lot like a go-kart. It's a very firm ride, so just realize that going into it. I enjoy them!
thank you very much.
considering most of your braking power is in front, to plant the car, I feel like a downside of coilovers would be less nose dive, aka longer braking distances
you have it the other way around if the spring rate is not excessive...you have more predictable braking and confidence...don't forget most coilover owners also generally run wider /better tires and better pads e.g stoptech sport pads = better braking...i myself went from stock 215 to NT555 245 all around.
Hey i just bought a dakota rt do you think if i stuck those on the back i be able to handle the torq a lil better
traction bar and stiffer springs check out bilstein
xxxMIGHTYDIPPERxxx thx my good friend
