I have spoken to a guy that has allegedly fitted a set of front brakes and rotors from a 380 onto an AWD magna for a comparison and they fitted. Obviously if they fit an AWD they should fit 2WD. Now i think he may have changed em over hub n all. Has anyone put 380 brakes onto a Magna?

There are three different cars with three different sets of front brakes.
Disc from 380 is 4mm thicker than one from AWD. If you change anchor plate and caliper you can fit them on AWD quite easily. Can you bolt on anchor plate from 380 straight to AWD I don't know.
To fit them on 2WD you will need to change anchor plate, caliper and dust shield as well.
Can you bolt on anchor plate from 380 straight on 2WD or you need to change steering knuckle as well, I don't know. Check this link for discs measurements:
