Tom, Henry has the info on the guy who does the macine turning. I don't have that wheel on my car anymore. I replaced it with a Derrington, which is larger in diameter. I recently had it machine turned also. Sorry no pictures. It cost about ninety bucks. I like the machine turning as fingerprints, smudges etc. don't show.
Will, I really like the look of those cam covers. I would be concerned about leaking around the seals. The stock covers don't look like much, but the don't leak either. If the Spyder guys have good luck with them I might give them a try.
