Really hope this issue can be resolved.

This is confusing. KW springs are stock diameter at the top, not 60mm, so you should be using OE style GC spring perch. Unless, of course, you are using non KW springs. I'm kind of leaning towards something not being assembled correctly or mismatched parts.

On the Ground Control Street plates the upper spring perch remains aligned with the strut tower, not with the strut axis. Therefore when you steer, the spring is forced to bend as the strut articulates during steering (which it does because of a combination of the camber angle, and the interesting geometry produced by the BMW's double lower ball joint design). A stiff race spring will not like doing this. Street style springs with a large upper diameter and a small lower diameter are more accommodating in this respect.
I am using the street plates with OE springs with no issues except that the urethane top does transmit quite a bit of tire noise to the chassis. I have no strange noises from the camber plates though.

On my previous car, I had similar style camber plates where the spherical bearing was used only for the strut shaft and spring was resting on the mount secured to the body. I had no noises using linear 60mm KW spring (same type as comes with Clubsport kit, GC, TCK, etc).
I'm glad you mentioned your street places do no transmit any noise other than tire noise. I have full GC kit being shipped out soon and I'm excited!
