R180 & R160 rear diffs

Thats a great help mate, so if i bought a STI R180 rear diff would that be a dccd diff (you know the controlable one with the button by the handbrake??) Also is it a direct swap with the wrx one, or do i need new drive shafts too????

The rear diff does not house the dccd, that is the centre diff housed at the back of the gearbox that allows you to adjust the power split. If you change to an R180 rear diff you will need the diff, shafts, hubs and read discs, lastly you would need a gearbox to match the diff ratio.

Yes you will have an R160 on your car and will defo be fine for 400bhp. A plated diff has a clutch pack in it, it's also ramped, so the friction when the 2 sides are spinning different will further load up the diff. Different ramp angles and preloading can set the diff to behave differently.
Viscous Diff (this is what your car will have as standard) is hydraulic based, but uses a thixotropic gel that resists sheer, loads up based on speed.
