3 Series Brake Rotors on 128i

[Athan_Hal]

I recently found some quality slotted and drilled rotors on a wrecked 3-series. Rotors are in great condition but unfortunately calipers are not available. I was wondering what I needed to do to get these to work on my car as they're a great price. Would I need some modification or part? or whole new calipers? Just wondering if they'd work with my 128 ones as I'm a bit uneducated on the subject. Any advice would be appreciated, thanks.
