- Time to figure out how to adjust coilovers on the Nissan 370z Nismo!
I recently installed the BC Racing Coilovers on my 2016 Nismo 370Z, and today we go over all of the adjustments for spring rate and ride height front and rear. Overall its not hard to do. It is just time consuming because you have to take the wheels off and lift the car up. Also there are endless ways to adjust them and you need to take the time to measure everything so you can make an even ride height.

Hey Brian, just had a couple comments for you. It looks like rears on the Z work similar to the way they do on my Sentra.
To adjust ride height, you actually need to adjust the collars on the struts and the spring. When you turn just the strut, you are pulling the lower control arm up into the spring, causing it to compress and adjusting your preload. This does lower the car but also effects the suspension dynamics, namely the minimum force required on a tire to start compressing the spring. By adjusting both the spring and the strut you can lower the car while maintaining your preload.
Preload is different from spring rate, and the only way to adjust your spring rate is to swap out the springs. BC sells various rated springs for their products and this affects the stiffness of the car.
On your question of when to adjust dampening, preload, and spring rate:
Preload: From what I understand you usually leave it alone, haven't done a whole lot of research on this but you do want to make sure that when your wheels are in the air there is enough preload to hold them in the seat, otherwise if your car's wheels leave the ground for some reason, your springs may fallout!
Spring Rate: This depends on what you want out of the car. Higher spring rates are generally better for the track as they can help limit body roll as well as help you feel more connected with the road and the car BUT if there are bumps anywhere on the track, perhaps you are cutting the corners, a high spring rate can cause the car to become unstable as it cant absorb the bump. It really depends on the track and also how much comfort you are willing to sacrifice for daily driving! A higher spring rate means a stiffer ride but it is also good if you really want to slam the car to prevent it from bottoming out when hitting bumps or dips in the road.
Dampening: Dampening adjustment is sort of a quick way to adjust the stiffness of the car. Cars nowadays are all critically dampened, meaning they don't bounce around after hitting a bump like you might see on older cars when their shocks go out, so all you are doing when changing this is adjusting the bump and rebound rate. For the track, you can do this to affect the weight transfer under breaking and in turns.
This is my understanding of how these things work but suspension dynamics are very complicated! Hope this helps! Looking forward to upgrading my Z's suspension to BC's as well!
The Carizon great info! With the rear end in the air, the springs won't fall out at all, they are definitly under pressure. Out of the box I basically lengthened the rear struts 3/4in. So I might need to add more preload to the springs then
My recommendation would be to not shoot for critical dampening, as the time for the wheel to comeback to its equilibrium position on rebound is longer than one would generally want for a maximally responsive suspension. I would start with minimal damping and gradually increase it in increments until the bounce just disappears and then back off a little, going for a one to two half-cycle overshoot of the equilibrium position. This setting will cut the time for the wheel to reach the equilibrium on the first rebound stroke to almost half the time for a critically damped setup. The amount of overshoot is negligible after that, in terms of the amount of elastic potential energy stored in the spring.
Rear spring perch adjusts the ride height, rear strut adjusts amount of preload on rear spring and needs to be adjusted accordingly to avoid bottoming out of the strut. Nothing adjusts the spring rate, however adding additional preload will cause the ride to be firmer.
Cole Hoover ok, so I should adjust that spring perch collar to be a little taller since I adjusted the shock to make it taller?
Bros FOURR Speed as long as the ride height is where you want it and the spring is still contained under full droop then you're probably fine where you have it.
I hate the separate strut/spring combos like these, they're a pain. But the main idea is that you adjust the rear spring perch to the ride height you want. Once you do that you adjust the strut to that at full droop the spring doesn't just fall out but at the same time making sure your strut has enough travel so that it doesn't bottom out over large bumps.
You can measure wheel gap at full droop and compared to on the ground and also measure your available strut travel at full droop and then subtract the difference of tire gap from your strut travel at droop to essentially get how much more travel your strut has before bottoming out.
Cole Hoover ok cool. So far the spring is nice and tight in place. But I might adjust it another 1/2 inch longer and then make sure the strut has enough travel to not bottom out
Rear spring perch ajustes the right and preload, it should be between 7-10 mm, then you hold it with a jack and adjust the strut to it to make sure the bolt goes through it smooth. That’s what I got from Bc racing. It made a difference on my ride after I did more research. If you just adjust the strut you’ll be messing with the pro load.
Help, I’m about to buy a base 2013 370z for my first car and I plan to throw those coilovers with some nice tires and a catback exhaust, is this a good mod list to start off with?
Did you get an alignment after?
What wheels are those?
Once you install coilovers , you need wheel alignment, check tread of your tires after few months, after a year. You have to change all traction arms. Ball joints and all other suspension parts, it happened to my G35. And you will hit lots of bumps on driveways.
Hey what type of camera did u use for the pics they look really good 👍?
Raul zuniga Sony Alpha A5100.
Might not be the aprópiate tittle For this question but Here is .I have decide to buy a 2018 370z But haven’t decided manual or auto. Some people. Say manual tran have issues . The other situation is theres sport package and sport tech. So i was hopping you can give your point of view on the nav system if its worth it or no
Edd, I have a red 2016 nismo tech, with the auto and paddle shifters. It might depend how you personally feel about a manual vs auto. I have owned about 36 cars at least 20 were sports cars and more than half of those were manual transmission cars. The most unbelievable of which was a 66 merc cyclone with a 390 in it and a 4 speed. I love the 'choice' I made with the auto trans on the nismo. The paddle shifters are great when I want to use them. I live in a large city and traffic can royally suck so those are the times I don't miss the manual trans. I did read a test in some magazine a few years ago stating that the auto version of this car is actually faster than the stick. Nismo Z's are hard to find once you settle on a year and color so the decision might get made for you by what you find available like when I bought mine 3 months ago. This guy's videos are great to watch if you are thinking about getting a nismo.
Where i live there are huges dips especially going into parking lots. Having lower suspension will definitely rip your front and rear bumper
Whats a good wheel and tire size for the 370z? Staggered?
The wheels and tires I have on the car in this verso are pretty good. All the specs are in the description
Did you have to buy camber arms for the wheels, as I know that only the toe-in is adjustable on my 370z.
I did not. They were able to dial in the alignment pretty good tho. Here's that video I had made. ruclips.net/video/9IegZC8J_kI/видео.html
@@BrosFOURRSpeed Thanks again. I'm probably going to go with some kind of coil over in the future, so many mods so little time.
Yeah there is a ton to do! Looking back tho, I would have got the same result lithesome lowering springs. I did the H&R springs on my Supra and GTR and was very happy with the, at a fraction of the cost
I may be wrong on this but I would adjust the final ride height with a half tank of gas and somebody sitting in the driver's seat whose weight matches the driver's weight.
Hey bro just letting you know, to adjust ride height on the rear you actually want to adjust the spring perch and not the strut. The strut deals with preload which is now off. I have the same coils on my 10’ nismo. Decent coils for the money.
George Acosta ok. So since I lengthened the strut. If I spin the spring colars down the put more preload on them like 1/2 inch, do you think that would be correct? I'm still learning lol
No worries bro. I’m still learning too. It was the first time I did coilovers so I looked up a few videos so I didn’t touch anything I wasn’t supposed to. But tbh I’m not sure. I would just reverse what you did to the struts and adjust the perch for height. Then start adjusting your dampening based on how the car ride is. I have mine at like 25 all around but still have to play with it some more because it’s not too great.
George Acosta the shock doesn't adjust preload, that also done from the spring perch by jacking up the lower control arm. Both of you guys are doing it wrong. At least call BC so they can educate you.
Uhh another line?? Kids can’t read a measuring tape these days. Geez
KillaBandit foh dino.
for real...those are 16'ths (or .0625") my dude
I like the look.....a lot. To me it's an improvement to the stock nismo wheel/stance.
Adjusting the spring preload does not affect spring rate. Just available right height. Your spring rate is determined by the spring itself, not how much it’s preloaded. Nice video tho. I have BC’s on my 98 LS400 and I love them. Enjoy that ride!
Sean Algrim Ok interesting. I love the new ride quality. Super stiff and solid feeling with no squat during acceleration
I love your car man
What size tire is on the z
All written in the description
How is the Size and width of your wheels ?
Vossen x Work VWS-3:
F: 20x10 +25 R: 20x12 +20
Nitto Tires:
F: 255/35 R: 305/30
What size wheels are you?
20in all around. 12 wide in the rear 10 wide up front
Test fit the rears in the front
I wish y’all would collaborate with Mayhem Morgan! That would be a epic video
How many 16’s are in an inch bro? And a line lol
Now you are ready for race track lol
tell us how the ride quality is!
So far... very good! I'll be making a video within a few weeks
If you invested in a quality set of coilovers, it would be much easier. Be prepared for those to seize up after 1 winter season as well.
Agreed.... he can buy some time with those boot cover things. This is the case where I'd actually ship my car to proven shop in the country with proven coilovers where they really actually know wtf they are doing. Sick of these McAlignment shops that have a new employee every 14 seconds but they are "experts" ? I love that every shop claims they are experts on every vehicle made in the past 100 years on every single permutation of aftermarket suspension set ups, and they'll actually look you in the face with a confident expression like a sociopath serial killer!!! Don't move to Oregon if you want a proper alignment, not a single human being in our state knows what they are doing. I'll FLY someone here or ship my Z instead.
Oh my, brings back memories. Unlike a track (for which most coils are designed) a typical road is a gauntlet of potholes, train tracks, sand, etc. Value priced coils just can't take it. Keep em *very* clean (especially the threads) and get a lifetime alignment deal from your fav shop. and good luck
TheVaughnShow Kill that noise you sound like a prom queen! BCR CO's are good mid to high range product (based on the performance pkg you select) especially with the type of car and power he has at the moment. Lol your speaking like he's pushing a GTR or something. Also BCR's typically fall in the top 10 when you do your research before purchase.
Fyi
Anything man made can fall apart, you can find pics and reviews online of every brands fails. FACTS!
Winter season? I’d hope he’s not driving it in winter and BC’s aren’t bad lol
Bc is known for their quality and winter? Lol there’s a slim chance he’s driving this in the winter so I don’t think he will face seizing issues lolz
It's all about the preload for ride quality.
Jeffrey Cattelino So far, the ride quality is perfect. Stiffer than stock and extremely solid over the bumps. Nothing bouncy at all. I might adjust the rear preload to help the rear stay a bit higher tho
You adjust the height from the spring... Not from the shock 👍
Yeah I ended up figuring that out lol. Definitely takes some time getting it all squared away
What tires are those plz lol.
255/35 F. 305/30 R.
Meant the tire brand lol but the size helps too. I'm trying to get me some grippy tires for my 370z
great videos!! but to adjust the rear ride height, it's done by adjusting the rear spring perch not by the strut.. exactly what Cole Hoover said.. car looks great!!!
here's a link to check out on how to adjust the rears
ruclips.net/video/2sXAIP7B5mA/видео.html
boon jing Yeh I'm going to adjust those maybe 1/2 in higher
He did this strictly for look! But he really messed up the ride and performance of the suspension. He really didn’t know what he was doing.
Personally I'd have the driver side spring sit sightly higher to compensate for my fat ass
Nooooooooooo!!!!! Why do people want to be garage engineers? The folks at Nissan nismo know how to set a car up - and they did. Now you go and “reengineer” the car in a garage over a weekend. Maybe I am just getting too old but I really don’t understand the tuner market - I’ve seen too many good cars get ruined. Plus - nobody will want to buy this thing after you’ve had your way with it.
Bros four are better engineers than Nissan. Lol. More like goof balls. Especially like the coin spring hatch trick. Did you see that video? I practically fell off my chair!
His brother talks about getting a "supercar" but ends up getting a Tacoma. Still any reference to a supercar from these boys is dangerous!
I get what you're saying, but nissan engineered the car in a mass produced way with performance, balanced with comfort and cost. If somebody wants more performance with sacrificing the comfort they can modify the car like this. Additionally suspension parts like these are more expensive than OEM because they have features not included in the OEM like adjustable damping and rebound, so Nissan was able to keep the cost down. But if a person wants performance for the actual track, or the car lowered for looks as well as performance, then these modifications are necessary
how to adjust your coilovers the wrong way
How so?
@@BrosFOURRSpeed your method for the rear in this video only ensures that you have equal piston travel between driver and passenger sides. The springs are what determines your ride height, not the struts.
Equal piston travel is a good thing to have, don't get me wrong
@@orangehammock I did end up doing that. Not sure if I showed that in the vid. But once it got the shocks even, the ride height was fine since the springs were even too
@@BrosFOURRSpeed it raised an eyebrow over here. You got a sub anyway and I'm currently watching the rest of your stuff.
Cheers from Dallas mate
@@orangehammock Thanks man!! The Z was a fun car to own, and I'll probably pick one up again. Some fun Supra vids coming!
Should have gone true rears , problem solved ,
Yeah looking back that would have been easier to do. But I didn't know about having all the weight on just the strut. With the separate coil, you disperse the weight a bit more
This will piss you off: Go grab a level, and toss is on that concrete slab your car is sitting on ;-) I think you need to find a shop that knows wtf they are doing and pay real/actual money for a corner balance with yourself and your woman in it.
Should have left the car original.
Still not low enough 👎
