i am a import kinda guy but my real good friend owns a GC and i know on an Import you can change the sway bars etc is that possible on a GC?

Sure you can change out just about anything. Addco make an excellent sway bar for the Grand Cherokee.

Alas, it's a jeep, not an import. It'll never be made to acheive tuner status, nor should it. If you want to scream around corners, go buy an overpriced Evo. If you want to do some hard core off roading, get a Jeep.
