I ran the 13.5 this weekend and I'm in love... Only problem is you need to get the smallest spur you can.... I ended up pulling the link ball screws out of the lower pod plate because the motor was up against the pivot....
Figured I'd share this tidbit....
I have to order that new car, I wonder how many are slated for shipping (on the 14th the site says) and how many are spoken for already....
