There is your proof that you NEED 18's

They look shit in 16's, just about passable in 17's but look the dog's funking danglies in 18's!!!

The RS with Superleggera's I'll bet were 19's - hard as fucking nails but impractical on a day to day basis (imagine having to replace the tyres every 6 months because they wear on the inside edges) and borderline pointless on a standard, non-wide-arched Focus.
