Well you COULD drop that far, but the only way to really do it would be to get a true coilover system, not those BS onese that just go over a regular shock......You would need a real coilover system that has shortened shock bodies to get the travel back....My friend used to have a B&G kit that was like 1300 bucks, it didnt bounce but rode stiff as hell... IMO, I agree with the other guys, you wont be driving very far with a drop like that without ripping your bumper or exhaust right off the car.
