To be safe, after placing the order, you should ask for a build sheet from your dealer with all the options and codes. If there's a mistake and you catch it before the car is in production, they can fix it for you. I was really lucky with Justin (board sponsor here) who added the paddle shifters for me without me asking... You don't see that kind of commitment from a dealer very often
