Physically it will fit, but the gearing might be wrong. The 318iS uses a 4.1 diff, don't know what the 316i uses.

Please also reduce your signature size, it's way too big :D

Don't know what the diff is on a 316 either, but it won't be a mile away from 4.1.
iS subframe will fit on complete, but you'll need the handbrake cables to go with it.
There's no great advantage in doing this unless you change to vented front discs as well.
