Are the SPL rear camber arms appropriate for a DD car?

[vqpower]

Hello,
I actually drive a G37S 6MT that is lowered on swift springs and is daily driven and will likely never see a track. I noticed that there are quite a few more users on these forums who use SPL rear camber arms than in the G37 community where almost everyone runs SPC. I was impressed with the build quality and robustness of the SPL arms and nearly bought them since I like to only put quality parts on my suspension. The last thing I want is the camber arms snapping in half during some canyon runs. However I learned that the SPLs use spherical bearings as opposed to the rubber bushings on the SPC arms. I don’t want to reduce the ride quality of my car or introduce any NVH so this is a bit of an issue for me. I would appreciate some input on these questions:

1. Do the SPL rear camber arms really introduce a noticeable amount of NVH?
2. Are the SPC arms of sufficient quality and durability for daily driving with some occasional spirited driving? Are they at least as reliable as the OE arms?
3. I am starting to feel that the SPC arms are probably sufficient for most users and that SPL is mostly justifiable for track/high performance use, is that the general consensus here?

If the SPC part is reasonably durable and will maintain the stock NVH characteristics, then I think I may go that route instead.

Thanks for the assistance

Read this. Most here like the SPL's.


Bad rear camber arm bushing

The SPL part gives you peace of mind. Mines not a DD but if I drive it to work its a 120 mile round trip going through the back road mountain driving and I don't think twice about the control arms going out.

I have spl arms front and rear, and put an insane amount of miles on myZ (150) round trip daily from the IE to the OC. You want cheap Spc. You want a worry free driving experience SPL.

I've said it once, I see it needs said again....

SPL! Do it right the first time! Tired of people buying $1000+ CBE's because someone said the quality fit and finish is so much better but for a part that could save your life people cheap out on less than $100! I don't get people's priorities!

You own a $30,000 car! Send the extra $100.

Yeah go with SPL, hands down. Yes they will introduce more noise to the car. You should be more concerned with the safety and performance of the part. You shouldn't cheap out on the suspension it can cause serious problems. Many people have had the SPC arm snap in half causing a lot of damage and costing the drivers a lot of $$$$.

Well I guess you wont be saying this for the front SPL camber arm which cost $700 +.

For DD its a waste of money and over kill.

Btw has anyone had actually experienced the SPC snapping apart while doing DD?
Please convince me. Otherwise you should be fine with SPC but if you do have the money for it go for the SPL. Its your peace of mind in check.

I decided to go SPL because I think the NVH shouldn't be imapcted too badly from just installing 2 camber arms with spherical bearings. It is honestly probably overkill for my street driving but I do like the peace of mind of knowing I got the highest quality arms available and I won't have to worry about it. The price difference isn't that much anyway for the rears.

I do think SPC is a reputable company and their arms are probably at least as strong as the OE arms. To my knowledge, all the cases of broken SPC arms were either due to install error, an accident on the road or some fairly extreme track use. I doubt the SPC arms would snap like that under normal street use. I won't be needing the front camber arms, but if I did I don't think I'd buy the crazy expensive SPLs for my DD use.

We aren't talking front. Front doesn't need any adjustment till you hit the track and need more camber and caster. If you'd read the post rusty linked you'd see your wrong. DD can provide plenty of harsh conditions and its not if a spc rear will snap its when. It's cheap china crap crudly painted that will rust out at the threads. It's a horribly disigned part with a built in snapping/stress point. This is why SPL uses titanium at the threads and its solidly welded at the joint unlike spc where they put the adjuster. If you want to mod like a civic then go buy a civic. If you want to mod like a big boy with a big heavy expensive car then do it right or not at all. I'm tired of these teenagers picking up cheap 370's and treating them like a neon/civic. Cheap crap parts give us all a bad name. My car at the moment is highly respected wherever I go. I don't need that to change because people start treating a Z like a ricer.

Man you completely missed my statement I know you are referring to the rear SPC vs SPL. Man Im with you that the SPL is a better quality than SPC. With the price difference of $100 hands down your better of with the SPL at the rear.
That is why I said it would be a different story if we compare price point via front cambers. There is a huge price difference.
By all means get the SPL if you can afford it.

On the other hand I was also stating if for a DD one should be good with SPC. Again like you have stated if your not such a "Big Boy" then go for the cheaper brand. I don't find anything wrong with that, not everyone are equally fortunate like others who can afford it, other would simply want to enjoy a small piece of enjoyment with a lesser degree of financial burden. That is why there are options to fit your purpose of usage and preference.

Well if you categorize people who buy lesser value brands as civic lovers thats you own stereo typing of people. I do not have an issue with that in fact I do agree with you at a certain extent.

But let me give you my own definition of the term "Big Boy"
For me This are the people who drive cars such as Porsche, GTRs, McLarens,Ferrari, Lambo and other list of super cars!

If by chance you have at least one of this cars then you are indeed a "Big Boy" but if you drive the same 370Z I drive Im sorry I guess we are still in the same category of whatever you want to call it.
Because if you refer the "Big Boy" just because your heavy with modding I define it as still a "Wanna be "Big Boy"

Hey Im not arguing or reputing your own opinion yet I do respect it....I would even say that you are Right! But as far as the "Big Boy" statement I do have a different view about it.

I humbly say Im not a "Big Boy" in my own definition. Im at peace with that. Lol

To OP

Honestly you did the right move in getting the SPL.
Im just giving my personal hands on experience with Rear SpC that i have used it for 2 years not have any issues with it.

So other forum members would have the opportunity to know that it would be fine to have SPC for DD. Depending how you want to drive your Z.

Unless the intension is to track the car or constantly drive it like they stole it, then I'll go for SPL anytime of the day.

[synolimit]

youre missing my point though. i wouldnt even run them on a DD. a DD will rust faster seeing weather. The SPC has a huge design flaw putting the adjuster where it is. at the bend were all the stress is, is just stupid. the SPL welds it solid at that point making it stronger. that kink and size of the SPC steel will fail over time. it may be solid and the SPL may be hollow but doing the math the SPL im sure is 2-3 times stronger. theres no way id put that on any car. LMAO!!! "not everyone are equally fortunate like others who can afford it????!!!" they bought a $400-$600 a month car payment! they bought the wrong damn car if they cant swing $100 for safety. and no, thats not why we have those cheap options. we have those cheap options because some kid in China making $0.05 a week makes them and sells them to us. SPC is to cheap to make them here paying at least minium wage.

my stereo type is 100% dead on. an old civic costs a few grand. a person with no money will buy one and mod accordingly. yes there are nice civics out there that run 10's and were done right but your average 16 year old with one who is modding it will show what he's worth. im trying to stay away from that as most used 09's still go for almost 20k. sadly there are still a few 16 yr olds that got their hands on them and are modding like a 16 yr old buying all the cheap crap they can afford. its sad. i wish my 13 body style changed more so im not grouped with them.

well term it how you will but the average american makes 30k a year. these cars cost 30k. most of american will agree with me and not you. you just named some people into the 1%'ers therefore dont count with me and the rest of the US.

you must be loaded then. my house mortgage costs $636 a month for just the house. if i bought my car on a 5 year it'd cost $645. to me thats a big boy car, not a little ricer civic with a fart can.

lol where you work? seems like i need a new career.

Thanks for the responses. I have no problems with paying the little extra for the SPLs, I think it's reasonably priced for a high quality part. My only concern is with significantly reducing the comfort of the car. Exactly how much of a noise, vibration and harshness increase can one expect from going from stock to SPLs? I really just don't want to make the car unpleasant to ride in.

You'll be happy... If anything car feels more sound.
