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

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.

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 $$$$.

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.

I don't hear any suspension noise and I have 18k front and 12k rear springs. Also heard no noise from the solid spl rear diff bushing. Only thing that's increased my noise was the hard tranny mount.

Dude, you have a choice:

1. Return the car to stock ride height and the stock alignment and your amenity and enjoyment will not suffer and your rear tyre wear moves back into the OEM zone
2. Stay with the lowering springs and put up with excessive rear tyre wear
3. Fit SPC components and enjoy the amenity of your ride because NVH will only be marginally increased
4. Accept the fact that a lowered "look" implies you are stepping away from OEM NVH (which is not that flash anyway) and do it right, which is SPL

I know which choice I would make - but no matter what we think, it is your choice to make.

Fair enough, only options 3 and 4 are being considered. I keep hearing that SPL will increase NVH but I can't find any description on how much worse it really is. If the difference is only mild, I think I'll just go SPL and call it a day.

Problem is NVH is terribly personal .... I subscribe to the theory that is it is too noisy, I will turn up the stereo. It is more noisy, but IMHO it is a modest increase in noise.

The fact that SWMBO hates the "noisy sports car thing" and refuses to get into it is the counter-point (and a side-benefit perhaps).

For a definition of SWMBO, refer to acronyms finder dictionary and abreviations finder dictionary - acronyms and abreviations list, definitions and funny acronyms from medical, military, army, training, business, internet, and emails. and search for this acronym.

Thanks for the link. It will be great at work! :bowrofl: By the way, think you have it backwards. HWMBO. She just lets you get away with it. :icon14:


I have the complete SPL front end. I haven't notice any increase in noise. But then I have the complete FI exhaust. :D

How often do the spherical bearings on the SPLs need to be cleaned/lubed? Since they aren't sealed bearings, don't they get dirty quickly?

Teflon...they say never.
