There is no rubber, so it's a race-type camber plate, but camber adjustment only. My caster numbers are still fine, so there is no issue there. You can get over 3 degrees with them. I have a pretty conservative ride height, and with camber plates max'd out, I am at -3.1. So definitely room for more camber if you drop the nose further, or grind shock tower holes in a bit.
However, even with sticky Trofeo rubber, -3-ish seems just about right both in terms of tire wear and pyrometer testing. Geometry on the E9X has definitely improved over E46....
