I did my first run at the track with the Dinan Stage I and the GC plates (the normal ones). I was at about -1.5 degress of camber before, -3.5 with the GC plates. There was more front end grip and the outside of my front tires were unscathed. I like the 3.5 because I could keep my hot PSI at 40 without killing the outside of my front tires. I could probably go with 37 or 38 hot and still be good.
I did warn the shop about the bolt plate issue before doing the alignment...even with cantrell mod.
