Upgraded to the MS diffuser last week, looking to sell my OEM rear aero in lightening yellow (both passenger/driver). They are in great condition, will put new polyurethane double sided tape on request. I'm not sure how much they go for but send me an offer and your zip code . feel free to PM me or call/txt me at 858-603-9484 if you have concerns, locals here in San Diego have priority.
