Rear diffuser fins for BMW M135i F20/21 Matte Black (2011-2015). This includes 4 fins with tape included. Doesn't require removing the diffuser, or replacing it. These simply stick to the bottom of the diffuser giving the back of the car a more aggressive look. Comes with double sided tape which is really strong and everything needed to install the fins. If installed correclty the tape will hold but, will peal of when you want to take them off and wont leave a mark. The fins are slightly different from the ones that are on the car and follow the line of the car they are just there to show you where they will go and where they fit. The fins hook over the inside of the diffuser for more support. They can be drilled in for extra support if you would like but should stay on with out. Cheap and easy way to make the car more aggressive.
