what type of shocks will work???

I'm in the process of bodydropping my stang but my shocks are keeping my car from getting really low right now. They run out of play when I drop my car and are probably keeping my car from dropping about 2 inches more. Does anyone know what kind of shocks would work best when I go for the bodydrop? I was looking into Air Ride shocks but I was wondering if any aftermarket shocks could work too. Thanks
