Hey Trey. Off hand I don't know of any body kits or suspension lowering kits available for 1998+ rodeo's - not to say there's none out there though.. As far as getting more punch out of your 3.2, there is a bolt on supercharger kit available thru:
http://www.alpine-developments.co.za if you wanna go the big buck route. If you want to go with the poe-man package, stick a cone air filter kit on it (just get a generic kit from eBay) & have a muffler shop make you up a nice cat back exhaust system (around $200 or so). It's tough to tweak anymore out of the DOHC 3.2 because of it's advanced control systems, 205hp's is pretty respectable from a stock 3.2 displacement. This engine has to be insane w/ a blower attached. Not sure how long the motor would last with a blower though.. G/luck
