SL/R230: Installing a carbon fibre rear diffuser to SL55
I recently purchased a CF rear diffuser for my SL55. After browsing the Internet I noticed there were two ways of installing this. One way was to take off the bumper and fit it with rivets and the other way was to stick it on with 3M tape or tigerseal. Either method, both required the bottom part of the bumper to be cut to allow the diffuser to sit in flush.
So my situation is I first tried it with the 3M tape / tigerseal way. After cutting the bottom part of the bumper, I test fitted the diffuser and noticed that as I align one corner flush, the other corner pops out (see pictures). Now I'm not sure if either the diffuser I got has a poor fitment or infact I do have to take the bumper off to fit it on properly.
Anyone who fitted the same diffuser, how did you go about installing it and did you come across the same situation?
Thanks in advance.
