PUL-MZMT10JDMRAD JDM Style Rear Bumper Lip Diffuser, unpainted, Compatible with Mazda Miata 2010-15 MX-5 NC2 NC3

Difficult to install the 3m tape did not want to stick to the plastic diffuser so I used bolts came out really nice but gotta put some time patience and elbow grease to make it looks good! All together if you know what you’re doing it’s great if you don’t then I’d have someone professionally install

This came with a roll of double sided adhesive tape. But the piece itself is so heavy the tape will definitely not hold it in placeI had to take this to an auto shop for them to install it with screws and paid extra just to install it

If you know how to use a screw driver, you can do this install pretty easy. I did this install by myself in my garage in less than an hour. Double-sided tape will not hold this. I personally went out and bought black, self-tapping sheet metal screws. I measured out exactly where I would like the screws to be before I did the install. I used seven (7) screws: one on each corner (can’t see in this pic) and then one in the middle of each fin. I choose not to screw in along the ribbed edge, as I figure they are more evident and will be harder to fill should I ever decide to remove this and go back to the OEM look. I even partially pre-drilled in the screws so they were ready to be fully screwed in the minute I held the diffuser up to the bumper. Then I slid my legs under the rear end of the car and used my thighs to support the diffuser while I held it up in place and screwed in the very middle screw. From there it pretty much supported itself and I was able to go around and finish up the other screws.
