Trying to compile a pretty comprehensive list of sub-$500 wheels here that are 20lbs or less. Please post with weight/size/offset if you know of others. I’m looking at 18" wheels here, obviously sub-20lbs is easy to achieve in 17". Pulled some info from this audizine thread: http://www.audizine.com/forum/showthread.php/444573-Lightweight-wheels thanks guys.

Enkei Racing RPF1 - 17.8 lbs / 18x8 / et35
