After hearing the complaints from consumers about inferior door sill covers over and over, we decided to make the only door sill you will EVER need to buy. These custom, one of a kind Door Sills are crafted from 100% hi-temp, hand laid carbon fiber for exceptional strength and durability. They are available plain or with various logos embedded beneath the heavy clear-coat. Installation is straightforward and NO DRILLING is required. I can't recommend these enough.
