10 PIECE MATTE BLACK ARCH TRIM SET FOR 2005 2015 AUDI Q7 S LINE Complete with double sided tape. WE ALSO highly recommend using POLYURETHANE black sealer on the inside of the arch to permanently bond the trims to the vehicle to avoid any coming off due to bad weather. THEY HAVE TO BE DRY FITTED TO THE VEHICLE FIRST TO GET THE CORRECT ALIGMENT BEFORE GOING AHEAD AND INSTALLING PERMANENTLY. FAILURE TO DO SO WILL RESULT IN POOR INSTALLATION !!!!! Dry testing will allow you to mark the correct alignment so each arch has minimal gaps from one another. We have supplied the arch trims for many years now , so the fitment is very good. Manufactured from Polyuerthane flexible plastic to make installation easier. Sometimes warming the each trim with heat gun or hair dryer gives you more flexibility upon installation. (instructions are NOT included, please seek professional installation from experienced bodykit installers) Professional installation is required to make sure all piece are aligned correctly before securing them against the panels. NO DIY installation or normal mechanic installation. Sometimes using heat gun to warm the tape and the trim will make installation easier (instructions are not provided)
