ROOOOOO-DEEEEEEEE... is the man when it comes to the drops...You don't necessarily need a new crossmember for your drop.
Will it be better? Sure. Not necessary though.
However, you will more than likely need the 4201 coils. The stock ones are too soft and you will probably end up rubbing occasionally. The 4201 coils wont drop you, they're just stiffer and will minimize rubbing.
