according to tirerack.com you can get up to 18 inch rims. But even with those you may have to do some modifying of your brake system. But every rim that i found for an 00 accord has a 5 lug pattern. Are you sure it is a 00 honda accord ex sedan? and are you sure you didnt miss a lug? Because i checked 4 different sites, and they all offered strictly 5 lug wheels for that vehicle. I own an 05 accord EX coupe and it has 5 lugs as well. But anyways tirerack.com has a lot of good wheels for you to check out. Not sure where to help you with the body kit though, im not sure but jcwhitney.com might have some stuff. Good luck, but if you are going to make it look nice on the outside, pleeeease but at least htat much money, if not more, into the engine to make it go fast instead of just look fast. My 05 accord ex v6 coupe with 6 speed manual tranny has 240hp and i am still not even thinking about accessories besides window tint, until i modify the engine even more... but good luck bro
