Hmmmm, interesting day . With no.changes except for the 2012 body set my car went from on rails to not driveable??? As crazy as it sounds I think the extra 8g of wing weight and the wing making more downforce threw it off. Another local had the same issue on bis car so I know it wasn't just me! I ran into this before when I was testing wings a while back with the 3r front wing . So I'm going to try and retrofit the f60 wing and see what happens, if it doesn't work then back to the old faithful f60 bodyset! Glad I didn't decal the 2012!
