Does stoptech do anything for the rears?
None of Stoptech's kits are made to be rear biased. In some cases, our kits can be more rear biased than stock, just not rear biased. Rear biased brakes create an unstable condition, which we would never do on a street car. Here is a link to illustrate that point. With rear biased brakes, the rear wheels would lock up before the fronts. While entering a corner, that would potentially cause a car to spin.
We have considered making a rear kit for the S2000 using our new ST-22 2-piston caliper (developed for World Challenge cars), but there has not been enough demand.

The SSR GT-7s fit with no spacer, with the standard offset from tirerack. 50mm. I couldn't believe it either but I've seen it with my own eyes.

Were these the 17" or 18" GT7's that fit?

How do you figure the S2000 is rear biased?
It has smaller rotors, smaller calipers and smaller pads in the rear. When my ABS kicks in it's almost always the front tires.

except that many many cars now come from the factory with rear biased brakes already (the s2000, G35 Coupe, 350Z, to name a few) and rely on the ABS to keep the rears from locking early.
As Ludedude said...look at the amount of brake torque that is generated on each end of the car. On the front of the cars you mention, rotor diameter and piston areas are bigger. If you hold friction the same in the front and rear calipers, you generate more brake torque on the front of the car...which means they are front-biased...end of story.

have you ever driven a G35 Coupe with the ABS fuse disabled? exactly what you say is what happens. It's pretty amusing. hit the brakes and it turns around.
remember that weight transfers to the front of the car during braking, rear biased means that the rears lock before the fronts. This doesn't require larger rear rotors. (although even my E36 M3 had larger rear than front rotors)
