Thinking about picking up a set of VRS 16' alloys tonight was wondering whats the best advice here, new to the whole buying alloys and wondering will these fit without issue or will i need to get them fully re tired in a thiner profile, car is at stock ride height currently.

Welcome.

If they are Mk1 Fabia vRS Alloys they will fit, and if the tyres on are the size that is standard on a Mk1 vRS Fabia then there is no problem with those fitting your car.
