I've been running 962s on my S13 for a long time now with this setup:
Front: 15mm spacer w/a 5mm spacer sandwiched (between the spacer and hub) and a 3mm spacer on top
Offset = +12
Tire size: 215/45/17 or 225/45/17 Federal 595RS
Rear: 15mm spacer w/a 5mm spacer sandwiched
Offset = +15
Tire size: 225/45/17 Federal 595RS
Here's a pic:

This is a "reverse" stagger where instead of the rears sticking out more than the fronts, it's the total opposite! I know it probably goes against the grain in terms of "preferred" wheel aesthetics but it's hardly noticeable unless you look really close or are really picky.
I haven't had any problems (i.e. vibration, wheel shimmy, etc.) running this wheel setup- I just check to make sure the spacers are torqued down to correct specs before and after doing a drifting event or after driving a lot of miles.
Hope that helps.
