Boxster vs Boxster S rotors:

Non'S':
F Disc 298mm, Pistons in Calipers 2x40,2x36 mm , pad area 216 cm^2
R Disc 292mm, Pistons in Calipers 2x30,2x28 mm , pad area 196 cm^2
Thickness (new): 24mm front and 20mm rear

"S":
F Disc 319mm, Pistons in Calipers 2x40,2x36 mm, pad area 254 cm^2
R Disc 299mm, Pistons in Calipers 2x30,2x28 mm, pad area 196 cm^2
Thickness (new): 28mm front and 24mm rear

S rotors are thicker AND larger diameter.
S pads are larger
S calipers bolt in place of non S ones

Boxster S brakes are identical to Porsche 996 brakes.

But I don't know a front rotor that's going to work off hand for the S. For the regular boxster, it's easy. For the S I'd have to start going through them part for part.
