I dont know much about the Tein setup, as I dont know anyone personally who owns that setup, so I havent gotten to test drive it. Out of all the setups I've gotten to drive (Intrax on stock struts, Eibach on stock struts, Intrax on KYB, Intrax on GAB, Eibach on GAB, Ground Control on Koni) I favor the GC/Koni setup as it's not harsh or bouncy, and has the most adjustability (adjustable damping and ride height).
I also personally like my GC/Koni combo because when i set my car up at shows, I can lower the springs even more to have the car appear even more aggressive. With the Tein suspension this would prove a lot more difficult. The ride height must be selected before you load the spring onto it and mount it.
I am not knocking the Tein suspension at all. I can only speak from my experience. I have heard though that the Tein suspension is very good though. But with the Tein you have a finite level of 10mm increments to raise or lower the car, while with the GC's the increments are what ever you little heart desires.
To get a proper suspension combo i would definately suggest the Tein or the GC/Koni setup i described earlier. If you want the most height options, or would like to vary them easily i would recommend the GC/Koni. If you dont want to have the option to easily vary the height, then go with the Tein as both the struts and springs were specifically designed in conjuction with each other to fit and work with the car.
lastly, about the camber plate issue... i dont have any, nor do i plan on getting them. i've had my gc's/koni's for about 8 months now riding on 225/40/18's and there is no un-even wear.... AT ALL. my rubber is toyo proxes and i've been pretty impressed w/ the fact that i drive so much and have very little wear at all.
time for lunch... =)
