It was not compatible with the Civic RS. I am selling it because I purchased it by mistake. It is unused due to the wrong size, but it has been opened, so please understand that. BLUE WIDE REAR VIEW MIRROR Product Number: 76400-BRM-004 Quoted from the official website: Spoon has used the technology of the "Hydro Blue Wide Mirror," which has been sold for a long time, to produce an interior mirror (rearview mirror). It adopts a curvature of 1400R to ensure a wide field of view. The blue optical treatment is also effective against glare. There is no distortion that is common with high-curvature glass. Installation is easy, just stick it on with double-sided tape.
