Where to find statement allowing 48in extension of your car for fuel economy?
I have read in a hand full of post indicating the DOT or EPA or other gov't agency allowing you to extend your car's rear end by 48 inches, but I can't seem to google up the supporting information for such a claim. I am considering taking the leap in modding my Saturn SL2's rear end. Just trying to find some info in the event that I need to defend myself from a ticket.
Thanks in advance.
