Front camber?

I must be a dumbass because I couldn't find this information either in the owner's manual or this forum. What's the default/factory specified camber for the front wheeels? I've been thinking about having them adjusted to help reduce the power-on understeer I've been experiencing. Good idea? Bad idea? What settings have people been using?

Steering angle Inner wheel 31°45’ ± 1°30’
Outer wheel (reference) 27°15’
Camber (selectable from 2 options) -1°00’ ± 30’ or -2°00’ ± 30’ (Left/right deviation within 30’)
Caster 3°55’ ± 30’ (Left/right deviation within 30’)
Kingpin inclination 13°45’ ± 1°30’
Lower arm ball joint breakaway torque N·m (in-lb) 0.5 - 3.4 (4.4 - 30.1)
Lower arm pillow ball bushing rotation starting torque N·m (in-lb) 0.5-3.0 (4.4-26.6)
Stabilizer link ball joint turning torque N·m (in-lb) 1.7 - 3.2 (15 - 28)

REAR
ITEM STANDARD VALUE
Toe-in mm (in) 3 ± 2 (0.12 ± 0.07)
Camber -1°00’ ± 30’ (Difference between right and left within 30’)
Thrust angle 0°00’ ± 0°09’
Upper arm ball joint turning torque N·m (in-lb) 0.5 - 2.5 (4.4 - 22)
Trailing arm ball joint turning torque N·m (in-lb) 0.5 - 2.5 (4.4 - 22)

Just curious--I can see why you would limit rear camber to reduce understeer, but why wouldn't you want the fronts to be at -2.0 or as high as you could get it with the eccentric bolt?

Just tire wear concerns? I've only tracked my evo with stock settings (I presume it comes set to -1 front camber, although I've heard horror stories about crazy factory alignments), and it understeered a fair bit. I'd been intending to get the car re-aligned in the spring, and I had planned on asking for "as much front camber as they can" and setting the rears to about one degree less than the fronts.

Extreme camber will not only wear front tires, but will make the steering pretty squirrelly on the street, especially on grooved freeways and patched highly crowned roads. I see you are in Minnesota, you know about nothern road conditions.

The rear end was way to loose on the street when I had those settings with OE tires... bumped the rear camber up to the .9 to 1.0 range and all is good.
