This is a high quality custom rear diffuser for the Datsun 280ZX.

It is CNC cut from lightweight aluminum, precision formed, and TIG welded. It is designed to fit with the OEM fuel tank but will likely work with a fuel cell depending on size and location.

The diffuser is open on the driver side to allow room for exhaust, but also has that opening mirrored on the passenger side for those running a fuel cell and dual exhaust, or for those who have a 1981 model with the exhaust on the passenger side.

Installation (though we recommend it be done by a professional) is fast and easy (see video below) and all of the needed hardware is included. In a matter of 30-90 minutes, depending on the installer, this diffuser leaves the back end looking clean but aggressive.

It is available in raw (unfinished) aluminum or powder coated matte black.

From Wikipedia:

When a diffuser is used, the air flows into the underbody from the front and sides of the car, accelerates and reduces pressure. There is a suction peak at the transition of the flat bottom and diffuser. The diffuser then eases this high velocity air back to normal velocity and also helps fill in the area behind the car making the whole underbody a more efficient downforce producing device by reducing drag on the car and increasing downforce.
