Stillen does run sales, especially at the end of the year.
Keep your eyes open, use an experienced installer/tuner (or install yourself) and you may well get away with 6K or a lot less. Some used kits being sold here are an option to consider as well.
Bottom line is, the car is fast enough to be fun without the kit. With this FI kit, it is much more fun. How much is that worth to you? What is your $/fun ratio?
