Yes, same dimension and they will fit like a glove. One small note: there is a hole in the rotor for a small retaining screw that usually holds rotors to the hub (while mounting), so rear drilled F85 rotors have that hole at a different place, so you won't be able to retain them with that small screw during installation (or you can just drill a hole for that if you must have it). Which is no big deal, as rotors are held by lug bolts/nuts anyway. So it's mostly a convenience feature. And after calipers are installed - during next tire change rotors won't come off as calipers and pads will hold them in place anyway too. Not sure if I explained it properly or confused you
P.S. Also it turns out there are alternative F85 rotors we can use: EBC company makes GD series black zinc coated slotted and dimpled rotors - same exactly dimensions as oem F85 only a bit cheaper:
drilled and slotted
GD1813 Front
GD1814 Rear
or just slotted (not drilled)
USR1813 front
USR1814 rear
