C6Z Front Shim affect on camber?
Does anyone know approximately how much camber each shim is worth on the top control arm? I am removing some for more camber.
Thanks in advance.

I think each shim is approx 1/2º, assuming you remove one from each bolt. I'm pretty sure I took 2 from each arm and went from -1.2 to -2.2, then later put a thin shim back in to get down to -2.0.
Someone else had a post on this more recently and may correct me if I'm wrong. btw, be carefull with the threads in the frame. If you damage them, you will regret it.

I agree. I usually take two out to go from -1.4 to -2.3. Last night I took an extra one out to get to -2.8. I'm not sure if my washers are the same thickness as the factory ones since I'm running a camber kit.
BTW, I reset the toe but as long as I am removing an equal number of shims from each stud should it affect the caster?

no, as long as you remove the same number from all 4 bolts, the upper balljoint does not move fore/aft relative to the lower ball joint, so the castor does not change.

A word of caution -- I mic-ed a handful of hardware store washers and their thickness varied by quite a bit. If you're trying to be precise check the ones you're using.

the average washer is made from scrap and that is why the vary. If you want consistent thickness buy graded washers like graded bolts.

Right, but as I only use washers to set caster or compensate for L/R differences I can fine tune it better with the varying thicknesses and then use a set number of shims to add and remove camber as needed.
