I think you are refering to the underbody kit with the front lip, side rocker panels, and rear pieces, all body colored. The cover shot of the latest Sport Compact has a Type R with the factory side and rear pieces installed.

It was only available from 98 on. The kit was not designed for the 97's with the different nose and rear bumper cover.

On the upside, and I did this on my 97 GSR, the 98 rear bumper cover (+ foam inserts) will bolt up without any problem on the 94-97's. The side skirts were common to all Integra's, so if you update the rear cover you can install the sides and rear.
The ITR has the front lip already, or you can by one from Comptech for a non-ITR.
