I guess it's my turn to chime in, I was hoping someone would of helped this guy out without me having to search around for pictures (Im lazy).
XslickwhitetegX & end005 are wrong.
There was a OEM Optional Aero Ground Affects Kit. For the 1990-1991 Integra 2 Dr Hatchbacks.
There are afew replica front lips floating around, But no one to date has made replicas of the side skirts (all pieces) and the rear lip.
I know of 1 person selling the entire kit (on the black DA is the actual kit) for $1500. They are extremely hard to find.
These are not my pictures, They are taken from members on G2IC.
The sideskirts are 6 pieces (3 piece per side). It consist of the skirt itself, Some cap type contraction on the fender's portion of the skirt and the piece on the door itself.
Any other questions just PM me or AIM: Haystacklivin510.
