alignment expert please comment

I had the car since November of last year and took the car in for alignment few months ago.
I'd like to hear some input basied on looking at my current alignment data. As far as i know this is not factory alignment spec.

front
-0.71 camber -0.51
7.59 caster 7.63
0.6mm toe 0.6mm (unloaded)

cross camber 0.19
cross caster 0.04
cross SAI -0.19
total toe 1.2mm

rear
-1.38 camber -1.25
1.7mm toe 1.7mm (unloaded)

cross camber 0.13
total toe 3.6mm

Currently using 225 17/255 18 S03 tires on the car.
I haven't been playing with the tire pressure much and
I'm also a track newbie, so I'm not very knowledgeable on different alignment setting.
Can anyone tell me how this setting will behave differently from stock setting?

Are you sure the front toe is positive?

I ask the same question as Dan, but I have seen worse.

Are you asking for street numbers or track numbers?
I run maximum negative camber in the front (around 1.5 degrees) and 2.5 degrees negative in the rear. I am using stock settings for toe front and rear. These settings give me fairly even tire temps at the track, but my car is ~400# lighter than stock. HTH

I agree get the front toe to be - or out,not + or in.Your camber and caster are ok,also I'm more into symetry and would want to see camber more equal right to left.

At this point i'm not very sure on the toe data, I will talk to the alignment shop owner this friday and find out the details.
The reason I'm posting this, is that my car has ALOT more under steering compare to my cousin's 91.
I went to lapping day with my cousin (nsxdreamer2) and instructor did told me that my car understeer more than his car. I've also experience it at group drive, where the road surface was wet, never really push the car hard, but I can feel the car was pushing at turns.

I’d check the front toe first. Front tires should be toed out (a minus number) and the rear tires toed in (positive number). For the track, you would want way more aggressive camber settings, but these settings cause more wear and instability on the street. I’d set things to the updated stock settings first and go from there. If you plan on tracking the car often then you might consider setting things on the aggressive side of the alignment specs (more negative camber, more total toe out/in front/back). To go outside these settings requires a goal, some book knowledge, experience and measuring equipment.

Good luck,
