is it even possible to put this on?

OZ make good wheels, and the ones you've singled out look like one of their nicer ones... I'd put it on my 240 or my GTi.
They will fit, provided the PCD is 114.3 and you do the 5-lug swap. Most OZ wheels tend NOT to come in 4 hole, so you'd have a hard time finding them if you tried.
The only issues I can really see you having is fender clearance if you want a lip that deep/big. Brake clearance on newer rims is virtually a non-issue, unless you have the larger Z32 brakes. In that case, you may want to do some measuring and/or test-fitting before throwing the money down!
