Keizer Magnesium center wheels?

["Kearney, Thomas" <Thomas.Kearney@usa.xerox.com>]

Anyone have any input as to the quality of these wheels?  I know I read a
while back about a Miata driver having problems with the new (at the time)
Keizer magnesium centered 3-piece wheels.  I also heard it might have been a
heat treating problem?  I'm looking at alternatives to the 3 piece
panasports (unless someone has some used ones in 4x100 13x8-9??) since they
are a bit on the expensive side.  

Thanks in advance,
