Hi great thread! New owner and very excited to find this upgrade to the base “stereo system” for my newly purchased 2011 135 (10/4 build). Getting ready to order my Alpine kit and corner moldings from Schmiedmann and was wondering if anyone who has done the upgrade can confirm the foam rubber inserts for the tweeters where already in your doors behind the blank panels? I see on Realoem the foam rubber “seals”, parts numbers 51337199589 and 51337199590 and was wondering if these should be ordered as well? Appreciate any feedback.
Really enjoying 1addicts and all the great information!!! Loving the 135 as well
Thanks - Chris
