$35 shipped, Just purchased to mount an OEM lip spoiler (from M235) on my f22. I bought the lip on this forum and had a body shop paint it and they put on their own 3m tape.
I will include a 3m adhesive promoter wipe and ship within the US. It is an unopened package with correct tape and 2 pieces for the spoiler ends purchased direct from a BMW dealership. Pics can be sent with a phone number or email as I don't know how to do it here.
