This is my tire leaning on its own from uneven wear. The left side is the outer edge. This is with -3.4 camber (front tire... rear looks similar). How much more camber should I add? I don't have a pyrometer, but the wear is pretty clear.

This tire is also street driven, and camber wear isn't too much of an issue.


Specs:
OEM CR suspension
17x8.5 rims
255/40/17 RS3
-3.4 camber front, -3.5 camber rear

 

just to clarify - you get more wear on the outside?

 

Correct.
Saw the tire myself, it's clear he needs more camber (I suppose technically it's less camber).

 

i need more also

how r u achieving 3.5 rear?

 

I have a J's S2 in the front, and SPC in the rear.

 

Correct.

In the background, you can see the same wear pattern on the rear left.

 

Looks like you do need more camber. My hunch is part of it has to do with the 8.5" wide wheel. I bet your camber would be more than enough if you were running 9 or 9.5" wheels.
