An air dam or "lip" fits under the front of the car, preventing most air from traveling under it. Sometimes it is called an air spoiler, but true spoilers are usually fitted to the rear. Air dams were part of the Datsun 1200 FIA homologation.
Preventing airflow under the car reduces pressure and parasitic drag on the under side. The result is less drag and less lift at the front of the car.

Mira

The most popular OEM air dam to fit a Datsun 1200 is a Daihatsu Mira part.

Mira front bumber: the earlier models 1990-1998 L200/201 series and the Mira TR XX are the sporter version that has a lip and side skirts etc. also i noticed there are a couple of different types, one has a rounder mouth like the pic and also one that is just a straight rectangle mouth.

Cut where the red line is and go from there, trim another inch or two until your indicators sit flush with the mira indicators slots. If i didn't 14" rims that wide then i wouldn't of had to trim the sides to much which looked better. Keep the grille if you can, mine was already broken so had to cut it out. Mira TR-XX has a better bumper more square and lip kicks out
