My front plate is not mounted right now. I have some strong 3M double-sided tape used for mounting automotive trim pieces and such.
I want to use this tape to mount the OEM plate holder, without drilling. I haven't done a test fit yet, but the M-sport plate holder does not seem like it has enough surface area to attach to the bumper with just tape, i.e. it looks like it needs screws.
