991 Illuminated Carbon Fiber Door Sills

The only option I wanted that wasn’t present when I purchased my car was the illuminated door sills in carbon fiber (it never occurred to me to ask the dealer to add the sills when I bought the car). I periodically lamented this omission and after a year of wishing and wanting I finally took the plunge. I never felt like the old inserts looked bad, but I always felt like they were out of place.

My local dealer was willing to price match a well known online vendor on the part and the quoted install price was reasonable enough that I was happy to have them do it (again, wary of doing any electrical work on the car myself). As it turned out, the total cost of the sills was only a couple hundred dollars more than adding the option when the car is being ordered new.

One thing you can be sure of: I will pick carbon fiber every time.

The carbon fiber illuminated sills look amazing. The “Turbo S” lights up in a very crisp bright white each time the door is opened and the carbon fiber insert is much longer than the stainless plaque. Admittedly I don’t notice it every time, but I usually do and it’s a very satisfying upgrade.

From what I was told by my dealer (and also from what I’ve read online) the install is difficult. In particular the dealership had trouble reprogramming the lightning control module. They also put a small dent into the door frame while removing the old sills (you can read about that here if you’re interested). Regardless, I’m extremely pleased with this mod and it will absolutely be included on my next 991.
