Crunch this

Ok so i've been searching around and looking at pic's and getting info on what offsets to run on my next set of wheels.  I've seen alot of PERFECT offsets but the actual specs aren't listed! So i'm hoping someone here can help me out. Here's the equation:

2nd Gen GS + Air Suspension + Shaved rear fenders + fender roller + 19x9f/10r 

[b]I want to run 19x9 +23 s-lo and 19x10 +9 s-lo[/b]

It's the lowest offset I can get in the wheels I want (and I am really set on) and the widest I can get as well.  Are these aggressive enough for a GS with air suspesion?

i believe there is a build up for this car here or on Cl. He is using spacers. 9 inch wide in front and 10.5 in rear i forget the offsets
