too much camber?

[mayorquimby]

i just installed new coilovers and adjustable rear toe link, camber arm, and rear traction arm. car looks sweet and i have negative camber in the rear. last night i was driving the car down some country roads, andi noticed that whenever i turned the steering wheel to the left the rear left tire would sqeak. kinda like if you turn the wheel real quick in a parking garage, where the concrete is really smooth. is that due to to much camber? any info would help.
