Spoiler supports and body panel supports (also called fender supports) play an important role in build of a track car. By using the correct material you will insure many trouble free race laps. There are different materials used for each purpose depending on the application. A front mounted or rear trunk spoiler will need a solid, no-flex support where a body panel support will have some "give" to it to rebound to it's original shape after contact. Each style is available in different lengths to make your race car build last many years of trouble free racing.
