thats a gt 5 door, not available in this country i dont think, so you will have to import one if you want gt spec....
the 16" wheels are big enough, mines lowered about 40mm with custom 13mm spacers and it looks perfect
imo.....
if your gonna change the wheels you may aswell try to get some with a low offset and that are wider than 6.5and you wont need to spend dosh on spacers then and use the standard 16" tyres keeps costs down.
search for pics of mine in nw meets and pics of clio tobys and jason e, they have done a few shops with different wheels......
depend if you want the motorsport look, jap look or euro look or a mix of all three.
rota slipstreams/gt3s, pro race/turninis and most of the keskin range look good.
or you could go the custom route with some porsche d90s or 911 reps...
