you CAN do this, but DON'T! the brake system is designed to have smaller caliper pistons in back than up front. the pistons on the boxster front are the same size as the boxster s front. this means that by putting the front calipers on the back, you change the brake bias.....a lot.

since the car dives when you brake, roughly 70% of the car's weight is over the front tires during a heavy stop. this means that about 70% of the car's braking power is designed into the front brake system. if the rear brakes are too big, the rears will lock up well before the fronts (particularly if braking in corners). the potential for spins is very real. just ask pedro.
