The sets are all included in te mod. You can download them individually from
www.pbw.cc Look for the latest Versions (Will say they are NEO Standard)
Most are v1.81
Look on the race web page at the Description to see the Version.
I hope to have enough donatons to keep the AST site on line so I can post the zips there for download. Right now its up in the air as to whether or not AST will remain on line so I am directly everyone to PBW.
