Cheap backup/winter wheels?

Sorry if this has been asked before lads (i ran a search but the closest answer was kinda old) but after needing a recovery truck to bring my fk8 home from a catastrophic (brand new pilot 4) tyre failure today i swore i'd bite the bullet and buy a backup set of wheels that i'll also stick some winter tyres on.

Can someone point me in the right direction - looks aren't important i just want whatever is cheap, preferably in 18's which is where it gets tricky with offsets and caliper clearance. I understand fk2 wheels will fit?
