The zender style skirts on the top pic are from a Houston area eBay seller and they are not good quality. Travis (forum member) has them and does not like them. I also saw them off the car and didn't like them.
However, budget skirts that look good are available. I bought and installed skirts from
www.gtmotorsport.net and they're great. Just remember that the 1/2 inch tape they supply you with is not wide enough and you should buy the 3/4 or 1 inch 3M tape to get them on your car solid.
