The door sills are custom designed by me for Porsche Boxster all year model. Made from 0.6" thick manufacturer grain stainless and 29" long. It is adhered with 3M double sided tape. Now comes with laser engraved 150 point font 986 ensignia. You could order them through my www.boxsey.com Boxster site.**This instruction is only for the door sills I designed.** Tools: Measuring tape Masking tape Bottle of Windex Wash rag Pair of Scissors 01. Start on either side of the car. This shows the driver's side. Remove dirt and dust from entire sill surface.02. Cut a piece of tape that is 15.25 inches long. Apply one end of the tape right underneath the door latch. Do not stretch the tape as you slowly press it down towards the sill (keep tape straight). Where the other end of the tape ends is the starting point of the door sill.03. Remove the white plastic cover of the door sill and place it on the sill where the end of the tape ended (do not peel double sided tape yet). Seat the door sill in flush so you have an idea of what it looks like.04. Now turn the door sill over and peel off all the double sided tape paper. 05. Turn the door sill back over and gently place it on the sill like step #3. Do not put pressure on door sill until it's properly lined up. Both ends of the door sill should be flushed with sill at the curve.06. The entire surface of the sill is not always flat. **important** make sure that the door sill is properly seated and flush before applying pressure to it. Apply pressure by pressing down on the door sill so the double sided tape can make contact with the surface of the sill. Once completed, clean the door sill of finger prints with Windex or any cleaning agent. Repeat the entire process for the opposite side.
