Lip Spoiler, Air Dam or Skirt : This type of bumper attaches directly to underneath of your existing OEM stock front or rear bumper changing the look.

Side Skirts: These replace your existing side skirts and can be easily changed to give your car a more aggressive and lower look.

Spoiler: Normally made of fiberglass and is bolted directly onto your car by drilling holes into your trunk. These are generally used for appearance.

Aluminum Wing: Aero-dynamic wings used for down-force or for appearance that can or can not be adjusted for height. Installation method is the same for a wing as it is for a spoiler.

If you install the kit yourself you will save money but the results may not be what you expected so ask yourself, "Should I be installing car ground effects myself? The answer depends on your skills, tools available and on the type of part and material selected.

Products made in urethane and with simple designs are generally easier to install because they are lightweight and flexible. They usually come with double back 3M high strength tape which bonds the parts to your car tightly. Some manufacturers (like Wings West) offer great videos and detailed instructions on the installation of ground effects for cars.

Products made out of fiberglass or with more elaborate designs, such as design style side skirts, require a lot of skills and experience. To explain it is important to understand the full process. Installation is not the only step required in order to have a finished product. Before final installation there is a "dry fitting" procedure involved which requires experience in order to accomplish it properly, then there is the prepping procedure, installation and of course painting. Dry fitting refers to the procedure where the installer makes all the necessary adjustment to the product in order to make it fit perfectly. It involves trimming, grinding and filling gaps in order to have the pieces fit the contour of the car. This is a procedure that is best left to a professional body man who has done this type of work before, since he can do it a lot faster and cheaper then someone who has no experience.

If you are considering the purchase of auto ground effects made out of fiberglass or with elaborate designs find the right shop to do the installation for you, before you make the purchase, to avoid unpleasant surprises. Look for a body man that has at least 1 year experience in installing all types of ground effects in different materials. He would be able to do the job in less time for less money, then a body man with 30 years of experience but who has never installed a car ground effect before.
