yellow speed racing coilovers
 

Hi all,

Is anyone running yellow speed racing coilovers for track car or at all and can give a review about them? From what I know BC racing is the big dog when it coming to coilovers (maybe I am wrong but this according to what I see and read) I got a good price on the 2 way kit but I can’t find a lot information out there when it coming to 370Z (even not 370Z it hard to find info).

Let me ask 2 questions:
Is anyone running them and can give a review?
What will you pick? BC (ZR) or Yellow Speed?

Thanks guys :tiphat:

Unknown brand with no info

Or

Any of the proven options

BC is entry level man
Along with Fortune, PowerTrix, Stance, Kw

If you are in the $1500 range you are entry level

If you are paying significantly less than that you are sub-entry level and better off staying stock and saving

Also if you are lowering the car you meed adjustable arms to fix camber, caster, and toe

I am sorry if I did not gave all the information.
I am looking at BC ZR https://www.z1motorsports.com/suspen...g-p-10320.html
Today I was at formula drift and seen yellow speed racing USA there. They are sponsoring some of the cars.

Not looking at entry level at all, my car is a TT fully build for the track.
I did install all this parts (car still on he lift):
SPL Front Upper Control Arms
SPL Titanium Rear Toe Links
SPL Titanium Rear Camber Links
SPL Titanium Rear Traction Links
SPL Eccentric Lockout Kit
SPL Solid Rear Subframe Bushings

I am not a drifter, but I do track nights mostly and looking for coilovers that will fit my needs. Also it is not my DD.

Hope this will give more information

I think I would look into fortune auto if I were at the level your looking. Built and serviced the US (with Taiwan parts, nothing wrong with that) and can be custom specced for you and your needs.

JRZ has a few options out there; pending on seriousness & price range. :ugh2:

At that level you should look into AST, Aragosta, or Ohlins

I stumbled upon YSR when I checked the racing coilovers available for dc5, they look like a big player in Europe, it is a Taiwanese company and they have extensive research on Honda platform like ep3, dc5, fd2 and sponsor some pro drifter. I think I will go with it for my race car as a start, they are a control coilovers on a racing series in UK and has many good reviews, at least for Hondas.


Anyway, I don't know much about their work on 370z, but there is other companies that have been more involved with us and they should have better products, also go with something that have support locally.

The real big dogs when it comes to coilovers are Moton, JRZ, AST, and Penske

Thank you everyone, I don’t know how much it is possible for me to go over $3000 for coilovers. Don’t get me wrong, I am not question the quality or if there are better then BC.

I am a family man and I don’t see the track as much as I like to spend $4.5k to $8k on coilovers.

Up to $3000 what will you recommend?

YSR have now a USA based company (still developing and creating everything in Taiwan) so I will be able to get the needed support. But I can’t find reviews in the USA for them.

One more thing I will like to add, I don’t know how to select the right settings for damping and rebound as I never did it before. If one of these options will make my life easier I may consider to go over my $3000 budget.

First you said you track the car then you said you don't....which is it?

Fortune Auto will get you in the 1500 range and sounds like you aren't going hard enough to need the next level

It is a track car and don’t DD it. But with that said I am not going to the track as much as I like. I am doing up to 10 events (if I am lucky) a year.
I have a full time job and a family so it not like I can go when ever I like.

Don’t get me wrong, I wish I was able to go more and I may be able to go more as my kid get older but for now I am going as much as I can not as much as I want.

Thank you for your help don’t get upset with me I just trying to select the right option for me.

So, what is it that you look for in the coilovers? What's not good enough about the stock setup?

Sorry, you are looking to change the suspension, but you don't seem to know what the adjustments actually do.

Edit: The ZR you look at is 3 ways adjustable (rebound, high/low compression)....if you aren't familiar with setting compression and rebound, plus the SPL arms, the infinite combinations will just make it easy for you to make a fine mess.

I am doing this for fun and fun only. Being going to track days for a few years now. This is the first car I ever mod and take to the track. I did took some driving lessens on the track to learn how to control the car better and how to take the right lines.
The first nod that I did to the car was TT (please let not go into if it was a smart first mod I can tell you it want but it a blest to drive). I am not try to go computation route by any means only to have more fun on the track and get the best out of my car as I can. I will say I am mid level driver and hope to go up as time pass.

What I don’t like about the stock setup are:
Body roll
I do think it is to soft for the tack
I want to lower my car 1” to 1.5”
Have better control over tow and camber

I do understand what coilovers will give me (just answered what I am looking to do) but I don’t how to do it myself.

For example there are 30 clicks from soft to hard, I don’t know how to pick the right but it do not say I can’t learn. I do believe there are pepole that can guide me and after I will play around with it I will find the right setting.

I am not a pro and not claims to be but I am always looking to learn something new and expand my knowledge.

Thank you! So if this the case where do I start? I was looking at the ZR because I did not want to get one set and replace it after a year or two but I may need to go this route.

Maybe someone else can chime in.... none of these complaints really relate to the shocks, or require adjustable shocks. Swift lowering springs and Hotchkis front bar will reduce the roll and lower your car. And of course SPL arms eliminate all the rubber bushings, which means keeping alignment on the correct curve.

Of course, if you are going to upgrade to coilovers anyway, then some may say just skip the lowering springs step.

Thanks for the input! I was told by one of the big and well known shops (I don’t say the name as I am not looking to give anyone a bad name for my little knowledge in this subject) that I need to go with coilovers. They are the once that help me with the bussing and all the spl parts.

Do you think this is a bad advice? Now I am kind of must go true coilovers at the rear as I installed all the SPL parts. :icon14:

Ah I skimmed over the fact that you are no longer running the midlink....is the ZR true coilover in the back? Most of the aftermarket coilovers for 370z are the OEM/divorced type.

Going SPL is never a bad thing though, especially for a track toy.

Yes they are, some of BC other types are not.

I'm so confused

You said you have the SPL toe links, which are only for true type coilovers

So do you ALREADY have coilovers? There's no way you're using toe links on stock suspension - the buckets hold the springs. The things you are saying do not add up at all so you are either making stuff up or terrible at communicating what you want. Either way, give us complete and true info if you want worthwhile advice

As for adjusting compression and rebound, I would start in the middle and adjust after DRIVING . Your alignment, tires, and driving style all affect the "ideal" settings

Better yet, find a good suspension shop that does track level alignments and talk to them and other experienced track drivers at your events and dialogue with what you're feeling. Have someone ride with you and talk about it

People here can give advice but no one can feel what you're feeling since you are the driver

Having said all that, I'd again recommend fortune auto, they make a true type rear, swift spring upgrade available, rebuildable in USA, custom damping available. Also, power trix is a Z specific company that can talk you through it

Hell, you're in Texas. SPL is right in your neighborhood

The car is on the lift right now so it is installed but never used yet (all the SPL parts) sorry if it was not clear.


Sent from my iPhone using Tapatalk

Your car is on a lift and you have the SPL parts installed?

Did it ever occur to you as you took stuff apart that there was nowhere to put springs with the toe link instead of a bucket/midlink?

This is why I say you're not being honest with us. You gotta by lying or incredibly oblivious to what's right in front of you

By and how did you become buy all the SPL arms without reading the description on their website or talking to anyone

Hell how did you buy all the arms without deciding what coilovers to get first?!

I am not lying to anyone.
As I said from the top, I was going with the BC ZR coilovers. I knew that I am going to to go the real coilovers setup. This weekend I can by yellow speed racing at formula drift, they had a stand over there like BC have and others. I went and talked to them so they showed me some of the cars they sponsor at formula drift. This is way I asked if anyone running them and can give a review on them and compare them to BC ZR.

As the conversation went on pepole put there other names that they recommend but it looks like they are out of my range but I never asked about them. I do thankful for pepole trying to help and I may picked the wrong coilovers (BC ZR) for the car but if you go to my questions at the first post I am asking about yellow speed racing reviews and to compare them to BC.

I have a 2 and 4 yr old. I have had very limited time driving the Z for the past few yrs. While having 3-way adjustments can be great, the combo of settings you like will take a long time to find, especially without lots of back-to-back drives over the same patch of road/track.

As Rusty will suggest, keep a notebook, log your impression of each setting, and have fun hunting for the feel that suits you.

Best of luck!

Thank you so much!
I know the feeling my kid will be 3 this January.
Love my family and the time we have together but need my “me time” in the car :-)
Thank you for going with me about everything and not give up. I know my English isn’t perfect and sometimes I have hard time to explain what I am asking.

Dude, you treat people like sh|t. Seriously. Every. Freaking. Day.

Stay on topic bro, this thread is about coilovers

I would second OZ for Fortune Auto, and if it was me, I would go for single adjustment coilovers, which I already did, it is more simpler to adjust and wouldn't need a lot of time to reach your prefered setting.

:iagree:

When you get into coil-overs with multiple dampening adjustments. You can really dial them in for a track, and they will be great. The problem with that is you can really lose your way with them too. Making them totally useless. It takes time and patience to find the right settings. Plus what works at one track, may not work well at another track.

Thank you guys! I think think I will change my selection to something that may be “simpler” but I will work for me and I will get the best out of it!

Is anyone have have info about these?

Someone recommended them to me today but I can’t find any good full review on them.
The guy that told me about them running a different Cusco set and saying he love them.

Do yourself a favor and focus on getting something a little less exotic. Just find a quality single (maybe double) adjustable set of dampers and start there. As someone else suggested, maybe try Fortune Auto. Good dampers have a finite life but normally can be rebuilt. Getting a set that ISN'T exotic means finding a place to rebuild them won't be nearly as difficult.

I'm happy with my Fortunes. OP you would also likely be happy with bc, feal or any of the other entry level brands that OptionZero mentioned.

Gomer is right. If you plan on doing this for a while, the coil-over will need to be rebuilt or you may want them valved for stiffer springs. It is a lot easier to do that when you aren't shipping your coilovers half way across the world and translating emails.

I had a set of Fortune 500’s before and I believe they are a excellent quality coilover for what they are a specially when trying to keep on a budget. Just make sure the coilovers you are using are valved for their intended purpose. If you use your coilovers for what they were built for look toward to rebuilding them.

For anyone with a $2,500 to $3,000 range budget, I would suggest the KW v3 coilovers if you are ok with a divorced spring setup.

All feedback i've seen is that the KW V3's are not stiff enough for track use, AND there is limited height adjustment. Seems like purely a street coilover for someone that doesn't want to be low

also, no pillowball mounts, rubber only. poop

you can do better for the price (and frankly i think you got the price wrong)

for 2.5-3k you are getting into Aragosta/AST territory, which is miles better

Looks like you don't know what you want exactly, Cusco is a great company, but you may not find support locally, specially when it is time for rebuild, and most JDM parts are overpriced in US.

Living on the other part of earth, I faced this issue, I had Zeal Function coilovers, they was a great set, but I had an accident and suspected they may be damaged from the impact and wanted to get stiffer springs, couldn't find any local dealer (which apply for all brands here :rofl2:) and shipping them + service costs + shipping back was nearly as much as new set of coilovers, I sold them for cheap, and bought a new set from MCA with custom springs and valving.

Fortune will be local to you, so you can save a lot in shipping, also, their coilovers are upgradeable, so if you got 500 or 510 series, you can upgrade them to 2-way or 3-way. They have a lot of great reviews and many members using them here.

At the end, the most important in coilovers are the shocks and valving.

Also, you need to be wary of spring rates with true type coilovers.
