hi, i would like to know if anyone can tell me where I can buy the rear diffuser on this civic or point me in the right direction and pricing if possible.

also, does anyone know how this mounts to the car?

sorry for the pic, i found it on the forum, thanks to the owners of the cars/pics.

thank you in advance.

There's some used ones for like $800 here: https://honda-tech.com/forums/honda-s2000-5/%7E%7E-official-s2000-sale-wtb-thread-%7E%7E-2499612/

As to mounting, your on your own. It's gonna be a custom mount as it's an S2K diffuser.
