The problem is that the design has incorporated the headlight panels into the front bumper cover. On the front of a DA Integra (90-93), literal linear feet of body gap have been completely remove from the front of the car by doing that. If the stock headlight assembly was still there, or a panel that is shaped exactly like the stock headlight assembly, then it would be illegal to tape up the gap between it and the top of the bumper cover.
I have the same issue with NA Miata's who use a hood that replaces the stock hood and both stock headlight panels. Where there use to be three stock body panels, they've been replaced with what's a single panel, and again linear feet of stock body gap are now gone.
Yes, pop-up headlights can be removed and replaced with something to fill the hole. Yes, headlight assemblies can be removed and replaced with something to fill the hole. But no where does it say those replacement panels can be molded into an adjacent panel, plus both taping up body seems and one-Piece front-ends are explicitly illegal. People can interpret all of this however they want, but then it's also up to them to prove that whatever it is they're doing is legal.
Personally, I continue to use a stock bumper cover and a fiberglass mold of stock headlight assemblies, with all the original body lines/gaps remaining. I then added a front air-dam that clips to the stock bumper cover, which is built to the limit of the front air-dam rules:
- Doesn't extend more than 4" above the hub center-line.
- Is entirely behind the vertical OE profile of the car, verified by running a plum-bob along the front edge of the stock bumper cover.
- An opening is cut in the exact shape, size, and location of the opening in the stock bumper cover that passes air through it (GCR definition of "grille". The stock one is right there behind it for reference.
Since I'm sure someone is going to either directly ask or just assume, no, I had nothing to do with this incident that David is referencing. I just happen to race one of these cars, have an opinion, and am sharing my interpretation of the rules and how I personally have chosen to approach them. I got approached too at PittRace because my air-dam had been bent up previously, wasn't straightened as well as it could have been, and did have a couple of spots that were failing a plum-bob test because if it. It wasn't a "gotcha" moment. It was an SCCA Tech Official going around and visually looking at cars and pointing out things that they wanted us to maybe take a second look at. No one got reprimanded, no one got it written up in their log book, just an FYI.

The other part that I was talking about is the flat air dam that most everybody is running that essentially eliminates the entire bottom half of the bumper.
See above. 100% legal to the rules.
9. A front spoiler/air-dam can be fitted to the front of the car.
A. The spoiler/air-dam shall not protrude beyond the overall outline of the body when viewed from above, perpendicular to the ground, or aft of the forward most part of the front fender wheel opening.
B. The spoiler/air-dam can be mounted to the body, chassis and/or frame and may extend no higher than four (4) inches above the horizontal centerline of the front wheel hubs. An intermediate mounting device may be used in locations where the front body-work is
above the four inch maximum.
C. The spoiler/air-dam shall have no support or reinforcement extending aft of the forward most part of the front fender wheel opening.
D. If the spoiler/air-dam covers any portion of the stock grille, an opening must be created in the spoiler/air-dam. The width of the opening must be equal to or greater than the widest horizontal measurement of the portion of the grille that would otherwise be covered. The height of the opening must be equal to or greater than the distance measured perpendicularly to the ground between the lowest and highest point of the portion of the grille that would otherwise be covered. The opening in the spoiler/air-dam must be symmetrically aligned in both planes of the grille.
E. Openings in the spoiler/air-dam are permitted for the purpose of ducting air to the brakes, radiator and/or oil coolers. Openings can be cut in the front valance to allow the passage of up to a three (3) inch diameter round duct hose leading to each front brake. These
openings can serve no other purpose.
