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
