Simon,
The CF wheels thread was closed because frankly it started growing tentacles and needed to be slain. Some members from here found a soft spot on the underbelly of a member on R3owners.com and it went down hill from there.
As Sullyjones stated there is an effort @ r3owners.com to make some carbon fibre wheels a reality.
If you do a search for "carbon fiber" on our site you can get a gist of the carbon fibre debate along with an abundance of gags, jokes and jabs.
Simon you can E-mail me privately if you require more details and/or information.
