Welcome BillSan.
I have a white base spec Clubsport too and the first thing I did was change the wheels!
I actually don’t hate the standard 18’s but they do sit too far into the arches in my opinion.
I had a set of 18” Pro Race on a mk6 GTI about ten years ago. They were very popular with the mk5 GTI race car brigade and were also fitted to quite a few fast road cars which ran modified brakes as there was plenty of room for bigger callipers behind the spokes.
In my eyes the nicest looking lightweight aftermarket 18” wheel is the Borbet FF1. High quality and OEM looks from an OEM supplier.
In your shoes I’d actually check out CM Wheels who do a range of replica VW style wheels that are of reasonable quality and go down either 18” Reifnitz, Estoril or Pretoria wheels route in 8x18 ET45.
I thank you and good night
