to make a whole new front, it is a little more difficult, haha and thats what i dont do...yet that is
i did make a front underlip, and rear diffuser....it does improves looks, and makes the car look alot lower than it needs to be, because my Evo7 is now about 1-2mm from the floor with struts
the piece of plastic that is on my front looks something like this
