It's the Victor LeMans. Not the lightest, but not a bad finish quality, and relatively inexpensive. Discount Tire Direct, wheeldynamics.net (and others) sell them. Not a bad looking street wheel...
How about these?... They're not really mesh style, but are good quality wheels that can be ordered in grey or black, etc, and are priced reasonably at Tirerack.
Check out the pics on the last page of posts on the thread. They have Boxster fitments too.
