hi all. after i bought my impreza 6 years ago one of the 1st things i did was swap to legacy rotors and calipers (unknown donor car). well i finally need to change the rotors again, but i cant remember if it has a 10.7 or a 10.9 diameter front rotor. and measuring the current ones i wouldnt trust doing they are rather rusted. the caliper is a 2 piston design if that helps.

No matter how much they rust, they shouldn't lose .2 of an inch, so you *should* still be able to measure.......
So you know they came off a 96, but not which model? Did you grab all four corners off the donor car? Do you have any recollection of the engine that was in the donor?

 

didnt grab all four, just the front calipers, bought new rotors. im not worried about them loosing size but gaining, there is a hugh amount of scaling around the outside edge, and not only that if im pulling these off (to measure) id prefer to leave them off. yea, i know im lazy guess the worst case scenerio applies here. gonna have to pull them and see
