Your center caps have either been stripped and polished, or they may be later replacements that lack the Enkei logo..

Most "directional" wheels are directional in appearance only. You could put them on either side of the car, whichever look you preferred. These Enkei wheels were designed to rotate one direction, although I can't remember which. IIRC, the preferred direction (to enhance the airflow around the brakes) was cast into the back of the wheel also - Left or Right.

Thanks Arne for the info.

Enkei Type 90. Came out shortly after the C4 was released. Mid-90s. Two-piece wheel, the center was welded into the barrel. Barrel was rolled and anodized. Center was clear-coated.

One of the first - if not THE first - aftermarket directional wheels, the beginning of that fad. Unlike most that followed, the Enkei 90s were semi-functional - there were directional ventilation vanes cast into the back side of the center, in hopes that they might help keep the brakes a bit cooler.

The Enkei logo will be cast in the back side of the center.

Did you mean mid-80s? Cool stuff!

Yup, that's what I meant. I'll correct my post above.
