Glad I found & read this thread. Didn't know anything about the front spring spacers or the side valances for the splitter. I checked mine in storage & the spacers were removed, but not with the car, so I called my salesman at the dealer & he didn't know either, but checked in the service dept. & found them in a box in the back of the shop. At least they didn't get tossed. I now have them safely stored in the console. Also the valances were installed. Plus for the dealer on this. Thanks for bringing this topic up.
