Deleting a spam post. However...since we're on topic:
Volk TE37 Mags in 18x10 +18 size, weighing roughly 14lbs! (and costing $1250 per wheel) combined with, oh, I dunno, Yokohama A048's in 285/30/18 for the long races and Hoosier A6's for the short races/auto-x?
Crazy bastard that I am, I'm going to get me some of these for the Altima coming soon in 2009.
