From the FAQ:
5. What is stagger and why do I need it?
If you look at the OEM wheel sizes above, you'll see that the OEM wheels have 1" of stagger for the AP1 and 1.5" of stagger for the AP2. That means the rear wheels are 1" wider than the fronts for the AP1, and 1.5" wider for the AP2. This is done in conjunction with the use of a wider tire, with a wider tread width in the rear. (See the stickies at the top of the Wheel and Tire Forum page for more info on proper tire tread widths.)
When choosing aftermarket wheels, wheels should be chosen that have stagger, like the OEM wheels. This allows you to use a wider tire on the rear, which is essential to proper handling and safety of the S2000. It is possible to run the same width wheels front and rear, and stagger only the tire sizes in a similar way to OEM tire sizes. However, this is not an ideal solution, because you may end up attempting to mount a tire on a wheel that's outside it's recommended width range. For instance, the popular 17x7" or 17x7.5" wheels that are so common. You could run the OEM AP2 tire sizes on these wheels, however the rear tire will be pinched on the rear wheel, because the OEM wheel is 8.5" wide. When pinching a wide tire on a narrow wheel, the intended performance and tread life of that tire may not be met.
So, when choosing aftermarket wheels, consider the tire sizes that will fit on them by looking at the specs of the tire you want to use (see the rim width specs), and try to maintain the stagger of wheel widths that the OEM sizes have. If anything, err on the side of a wider wheel and tire for the rear as this is the safer solution.
On a final note, here are a couple of links Xviper pointed out that are very helpful.
