Here is a tip for those who are not sure if they want the fender shields on their car or maybe you only want them on some of the time. Buy a pair of the Ferrari OEM 3D resin fender shields. You can find them on Ebay for $20 a pair. Then go to Office Depot or a similar store and buy a package of the thin magnetic sheets that are used to put on the back of business cards. These sheets have one adhesive side. Stick the adhesive side of the fender shield to the adhesive side of the magnetic sheet ( it will thake two sheets to completely cover the back of the shield. Trim the excess magnetic sheet with a razor knife. You now have a fender shield that will magnetically adhear to the car and can be removed at any time without leaving any marks on the car. There may be some speed at which these will blow off but I have had mine on up to 90 mph without problems.
