Default Camber/Caster/Toe how bad the situation

Hi. I just got the car from the repar shop with the following
camber/caster/toe parameters:

Left Front:
Camber: -0.6 (Actual) -0.75 (Min) 0.0 (Nominal) 0.75 (Max)
Caster: 0.9 (Actual) 1.23 (Min) 2.23 (Nominal) 3.23 (Max)
Toe: -0.09 (Actual) -0.06 (Min) 0.0 (Nominal) 0.06 (Max)
SAI: 16.3
Included Angle: 15.7

Right Front:
Camber: 0.3 (Actual) -0.75 (Min) 0.0 (Nominal) 0.75 (Max)
Caster: 0.5 (Actual) 1.23 (Min) 2.23 (Nominal) 3.23 (Max)
Toe: 0.37 (Actual) -0.06 (Min) 0.0 (Nominal) 0.06 (Max)
SAI: 15.6
Included Angle: 15.9

Front:
Cross Camber: -0.9 (Actual) 0.0 (Nominal)
Cross Caster: 0.4 (Actual) 0.0 (Nominal)
Total Toe: 0.28 (Actual) -0.12 (Min) 0.0 (Nominal) 0.12 (Max)
Set Back: 0.08

Left Rear:
Camber: -1.0 (Actual) -1.5 (Min) -0.75 (Nominal) 0.0 (Max)
Toe: 0.16 (Actual) 0.02 (Min) 0.04 (Nominal) 0.08 (Max)

Right Rear:
Camber: -1.0 (Actual) -1.5 (Min) -0.75 (Nominal) 0.0 (Max)
Toe: 0.03 (Actual) 0.02 (Min) 0.04 (Nominal) 0.08 (Max)

Rear:
Total Toe: 0.19 (Actual) 0.04 (Min) 0.08 (Nominal) 0.16 (Max)
Thrust Angle: 0.12 (Actual)

The car seems to be stable. I tried sharp turns, fast acceleration,
highway speeds. However the numbers are not within the specification.
Can anyone tell me if I should fix it and what kind of problems I can
run into if I don't do it.

Thanks,
Alex

Cross camber is a little to high, could lead to a r/s pull, caster is too
low, affects steering stability, Toe in front and rear is off slightly, may
affect tire wear slightly. Caster seems to be the biggest out of spec.
Nothing catastrophic here though. Some vehicles the caster and camber (
front) is not adjustable, or can add expense to do so.

Your caster is the farthest off. Caster is not a tire-wearing
parameter... however... you may find that the steering wheel doesn't
return as well as it should after a turn.
