First, welcome to the site. Anything you ever wanted to know about your contour is on here, or can be asked. I reccomened fimilarizing yourself w/ the site. My Home at the top allows you to edit your signiture, etc. Put your car year, model, engine, etc in your sig so when you ask questions people can help you more. Next, you stated that your car is a 4cyl, so you have a Zetec. If you want to do mods, check out the stickies in each forum... engine mods in Zetec Performence, suspension in the suspension forum, etc. You also want to check out your local forum on the bottom half of the main page to check for meets and events in your area. Lastly, remember to search! The biggest mistake noobs make is asking questions that have been covered many times. Search for your question, and if you can't find it, then post about it. Specs and info are available on the main page, contour.org. Have fun at CEG, it is a great place with unlimited knowledge available!
