981 versus 981S caliper

[IProkopiw]

I know rotor size is different, both calipers 4 piston (one black versus red) but any other difference? As an aside, are wheel carriers the same? Looking at putting 981S rotor/pads onto 981.

There is no difference in the wheel carrier on 981 and 981S.

Of course you know the rear brakes are the same for both 981 and 981S?

The 981 S front rotors are 13.0 X 1.1 inch, rears are 11.77 X 0.80 inch, the non S fronts are 12.4 X 0.80 and the rears are the same 11.77 X 0.80 inch. As Loren noted, the carriers are the same.

So do you think I can simply put the 981S front rotor on the 981 without problem (except pad change)?

Not without checking to see that the calipers are also the same, which I would be will to wager is not the case.

I have looked this up on the PET on a dealer parts site. The calipers are indeed different part numbers, even though they look identical.
