These piccies were posted by Shazzam a short while back, under a thread asking about carbon wheels and their suitability or not.
If your interested there is a reply from BST on there I beleive and it does make interesting reading.
Don't know how to link to another thread, but do a search under carbon wheels and its dated the 10/12/04 (started by Rob).
