   *All weights are from items I weighed on accurate Intercomp scales or from various other references assumed to be accurate.  This is only a guide.  This intended to give you weight information so you know where the easiest areas to save weight is.  All cars are different.  Just for example, fox body Mustang door crash braces have a weight variance from about 11 pounds to 18 pounds based on what others have weighed.  This could be because there were a few different door crash braces used in these cars or it could be that others did not completely cut out the braces and only removed a portion of it.  I cut the entire brace out and it weighed 18 pounds.  So again, this is a guide and should be a fairly accurate guide.  If you want total accuracy for your specific vehicle, weigh your own parts to know for sure how much weight you are saving.*


  *Every 1 lb reduction in rotating mass is equivalent to an approximately 8 lb reduction in static weight* (re: Centerline Wheels website)
