These carbon fiber door sills are not an overlay over existing part. A very high quality epoxy, matched with the best clearcoat makes these pieces an eye catcher to anyone at a car show or your next car meet.
Please state in the notes if you want an Audi Sport, A4, S4 or RS4 decal. I can also do custom decals. 
*These are made to order. 6 to 8 weeks lead time minimum.
