Best Honda Civic diffuser available

An absolutely amazing diffuser 10/10. Some things you should know before buying if you are planning on installing it on a ***2019-2021 sedan LX***. You will have to drill holes in your spare tire wall for the brackets to grab on to, which is no big deal and if you space them correctly you will have no issues with your spare tire rubbing on the top of the bolts as there is plenty of room in there. Second thing is, the side pieces of the diffuser are held up using the plastic clips on the underside of the rear bumper and they work very well with one exception. The side piece of the diffuser that goes on the drivers side was not held flush with the underside of the bumper because there is no plastic muffler shield on the drivers side, there for the plastic clip was a little loose. An easy fix for that is a couple of washers on the opposite side of the bumper from the side piece of the diffuser to give the plastic clip more to grab onto making it flush. Again, this review is for a ***2019-2021 sedan LX***. Definitely one of if not the best mod for my car so far and it looks amazing.
