First off, welcome on board!
IMO the 18" wheels are fine for ride comfort etc, I've had nothing else for years.
The Edition 30 wheels are made by BBS for VW and are called Pescara's. Very VERY similar to the BBS CH's, they are 18"x7.5" ET51. If you want a slightly better stance and better clearance if your getting a BBK then look at the BBS VZ's (as mentioned) as they are 18"x8" ET44, so loads more room inside the wheel. Speak to Graeme at GNJ_Motorsport on here if your after these. Here's a link to the Forum discount prices.....

The Carbonio and papal filter is a lot for what it is, you'd be better off with an EVOMS CAI or Neuspeed CAI for a similar price or a Forge Twintake, ITG system, REVO or APR/VWR cold air intakes. All good, range from £200-£450. Google these kits to see what's what.
