Max rear camber available?
Anybody sweep through the rear camber? I'm currently reading -1.7L/-2.2R at RS height and want to get an idea how much more is available. Please post your ride height too, lower height should allow for more total camber. Thanks!

I had mine at a bit greater than 3 but run at 2.5 or so and find that works for my setup

I'm sure I ended up with 2.5 on mine at 25mm below rs height. I remember my alignment guy trying to get more, which he could, but at the cost of too much toe in which he said would have a more negative effect than not getting that last half a degree of negative camber that we wanted. I've since fitted camber plates on the rear but haven't been back yet to get it corner weighted and set up so will probably end up at 3 degrees negative camber.
Just to add a bit more info in case anyone finds it useful, my last two sets of rear tyres wore perfectly flat with this setup. That's with a mix of track days and fast road driving, no commuting.

Thanks for the helpful replies! Looks like I can find another -0.5° in the rear at RS height, which will definitely help. My street tires typically age out, so the extra camber shouldn’t be much of an issue for street tire longevity. And with the C4, no real loss in straight line accelerating traction with the more negative camber 
rsclone, thanks for the note about how the rear camber and toe cross-talk. The Tarett 935 style spring plates appear to be the only option for more rear camber. Major bonus- they tell me that camber can be adjusted on them without affecting toe. That would make it easy to swap between Hoosier and street/rain tire camber.
I’ll see how the front camber plate camber adjustments effect toe when I bring it in to the alignment shop. My guess is that tipping the top of the struts inward for more camber will increase toe-in. Will find out...

And the answer is: -2.6° rear left, -2.8° rear right. Not too bad! Shop got the rear toe just inside the spec at 0.11° on each side (spec, in degrees= 0.08-0.25).
In the front, I’m up to -2.2° camber on both sides. It looks like adding -0.6° with the camber plates increased the toe-in by 0.4°. Front toe was set back to 0.22L/0.20R, spec is 0.17-0.25° toe-in. I usually run 0.1, but forgot to mention it this time around.
Another bit of data, the extra 0.6-0.9 negative camber in the rear tucked the top of the wheel under the rear arch by about 6mm.
Looks like I’ll hold off on the 935 spring plates for a little longer.
