Is it possible that SPC had design/manufacturing issues that may be have been corrected in recent years...or is SPC still unacceptable for track use?

I am not concerned about the extra $300...rather I am concerned about the "ride" on the street with SPL. Are the spherical SPL bushings going to be noticed (by my wife) during weekend driving?

I don't use SPL because they're illegal aliens in STR lol however the new SPC arms look better than the old design:

I'm using the z1 street arms:

I know people were reporting issues with the ball joint coming loose, but I have not experienced that issue. If you go z1 make sure to use the proper thread locker and let it cure 24 hours before driving.

They aren't bad either for street driving, they don't make noise and camber adjustment I'm told (by the technician) was easy, but I did take it to a professional race shop for the alignment. Hope this helps.
