23 inch Universal Car Rear Bumper Lip Diffuser Shark Fin Style Bumper Spoiler,Glossy Black

The fit and finish on this part was incredible. The thickness and strength are much better than expected, especially for such an inexpensive item. The arch of the part matched perfectly to the bumper on my vintage Miata, and it's size and style fit the right look. Amazon warns... this is a " high return item" , and suggests careful measuring before ordering. I would also recommend while you measure, consider the placement of the item. I mean is there enough surface area to mount it, low enough, that you will like the look. On my application, the bottom lip of the Miata bumper only extends about 1" under the car, and I had to make a custom bracket to support the front lip of the diffuser. It was well worth the little extra work, for the end results. Thank you Amazon for such a great quality product at a fair price!

Fit on the custom car I built

A very nice diffuser for the money! I put this on my 2015 Infiniti Q60 convertible and it looks great. Be sure to measure carefully, because the fit will be the key to success on your car. Because my rear panel has a bit of a curve to it, I used some nice looking black panels screws to secure it on all 4 corners, but they're hardly visible and guarantee that the adhesive won't let go and drop your diffuser. I'm glad I got this one for my car!

ok

I'd give it 3 1/2 stars but review doesn't allow for it. The reasons for this is that the curve of the part is too extreme to match any underside car bumper or body. The only place that this piece of molded plastic would possibly work is on a curved roof surface. Also there is not enough flat surface area underneath to affix the piece to any surface of the car. The edge is only about 2mm wide and most tapes are quarter inch and bigger. So I sufficed to gluing the part to my car with silicone sealant not easy and not the most visually appealing fix but it worked. I put it out in the hot sun to make it easier (flexible) to work with. After installing the look from a distance is acceptable.

This is a universal type solution, I could not use the 3M adhesive as that would not hold nor did I use the the silver screws that are supplied but some black ones I had ( hint, silver screws on glass black are ridiculous! change them) It fit perfectly for my application and for the money reached the look I wanted. Install was 10 minutes.

Easy install. I would absolutely recommend.

It was was a good quality
