Look up the bolt pattern for your car. Look up rims with that bolt pattern. find a cavalier forum where you can ask about the rims offset, width, etc., once you have one picked out.
You can also use a site like tirerack.com or discounttire.com. Put in you car's info and it will list rims that will fit.
Much better selection then Tire Rack or Discount Tire.. It will also provide you with bolt pattern, offset, max size, max width, etc.
i have subaru wheels on my cavalier and its the same bolt pattern
