Found my front end noise!!! UPDATE
Those that have lowered, and installed SPC camber arms, and have noises, check this out:
The pressed in bushing has slipped on mine, check yours.
UPDATE:
I sent my arms back to SPC, they agreed there was a defect in the bushing.
All 4 bushings were replaced, it was mentioned that the new bushings pressed in with no less force than other new ones, so they concluded the arms them selves were ok.

Squaking/groaning (for the lack of a better term) over speed bumps and dips.
Similar to a dry urethane sway bar bushing, I disconnected my FSB, noise still there.
Loosened the upper control arm bolts, suspecting noisy bushing.
Noise went away due to bushing not needing to rotate within itself.
The noise is the arm rotating around the outer bushing sleeve.
I left a message with Lou to see if SPC will warranty this, as its under a year old.

Who performed the installation? The suspension components should be tightened with the car weight loaded on the suspension. If you tightened the A arms while the suspension is unloaded, once the car is lowered onto the ground, the A arms will be pushed up by the weight of the car. This will place strain on the bushing and cause it to tear.

I did, and yes, the suspension was loaded.
I have posted that warning a few times here.
Look at the last post in this thread from August:

I WAS a front end tech for over 13 years!!!!
Look at the picture, the brass outer bushing sleeve has moved.
That is a press fit, obviously not within tolerances.

Looks like you just got a bad part. Like you said, that shouldn't be able to move out like that if the part is built to tolerances. I'm willing to bet that SPC will replace that for you with no problem.
But since it happened to you, it would be a good idea for every SPC camber kit owner to check this the next time their front tires are off even if they don't have noise, just in case. Thanks for sharing it with the community.

you were suppose to install those red nylon o rings on each end where the bolt goes through to avoid metal to metal contact. 4 on each side. might wanna check that out also.

The inner bushing sleeve is supposed to be metal to metal to the body, as the bolt locks down the inner sleeve, the outer sleeve is pressed into the control arm hole, and is stationary relative to the arm.
The rubber between the inner and outer sleeves is the rotating isolator.

It's 52 ft lbs. to be exact.
It's a simple manufacturing defect. The bushing, where pressed into the arm, slipped out.
It has nothing to do with installation.
I've seen this many times on early GM A and F bodies, but those arms were stamped steel.
