The proportioning valve may be different, as may the master cylinder - I don't know for sure though.

what about the slotted and dimpled rotors on 935, I want slotted but want the look of crossdrilled also at the same time with out the possibility of cracking , so say would the dimple really hurt anything in your guys opinon

Not as bad as drilled, but it's still creating a weakness. Like was stated before, if this is just a street aplication, I wouldn't worry about it too much because you just won't be putting the same stress on the rotor.

90-93 Celica Alltracs have 15/16" bore MC w/o ABS and 1" if you have ABS.

Not that I know of. I have a set of Alltrac calipers that match the set of GT-S calipers. 50mm fronts and 35 mm rears. Anyone with an ABS car can measure theirs to verify, but I doubt it.

Calipers are the same, but the porportioning valve is different.
Only the front lines are different. Rears are the same.

*One other factor, do the 184s/185s have the same brake porportion? If not, changing to a 184 non-abs porportioning valve will change the front/rear bias. Not sure how much it matters tho :shrug: *
