no its not z'd yet i think it only takes 3/4" to lay all the way out but most people do 1". ya theres a couple crossmembers that hang below the frame so if you wana lay flat on the frame you gota cut up the two crossmembers. i havent really did much to the truck lately but i did pick this up
gota fix a bunch of stuff to get the 4g63t running and im thinking about maybe using the irs out of the talon for my truck. not sure yet.
