My rims are used and came with Cougar tires, so its a cheap form of lowering it a good inch or so. I bought them off a guy I know in Carpentersville (near Chicago) who had them on one tricked out Dodge Avenger.
He helped me put them on and everything, we even painted my calipers and drums with red high heat paint. I did have them aligned just to be safe because it drifted a little to the right. And I just had them balanced with tap-on weights after my recent accident. So now it drives like butta down the road!
Try to find someone you know who is selling used rims to start off, shops tend to get annal on their prices (unless you find a nice set that'* on sale). Last time I checked Tires Plus in my area was selling 16" American Racing "Avenger" rims for $80-$90 a piece, except they were pollish rims and pollish rims are harder to take care of than chrome.
