                               BODY BUILD

rand Am rules are very specific when it comes to body design.  The rules allow the panels to be replaced with carbon fiber as long as they directly replace the OEM panels.

The rules also allow and require the body  to cover the wheels but only allow the body to be widened above the hub center line.

The use of a Nismo kit ( the same kit allowed in the GS class) as a base was approved by Grand Am.
  Below the hub center line the body has to return to the OE width.

While the chassis was under construction the composite shop used a second tub to model the body.  We used very thick fiberglass parts made from our GS tooling to base the GT body on.

Foam and bondo were used to create the shapes for the new wide body.  Wood templates were taken from one side and transfered to the other side to create a symmetrical body.

High temperature tools were constructed from the finished buck.  All of the OE flanges and returns were incorporated into the tooling.

The new parts directly replace the original steel parts.  By drilling out the OE spot welds and removing the OE panels a person could replace their steel body parts with the carbon parts and simply rivet the new parts to their car.

We manufactured  the body using 2 ply of carbon on the inside, Nomex honeycomb core, and three ply of carbon on the outside.  An example of the weight difference is the OE steel roof weighs about 17 pounds and the carbon roof weighs about 4 pounds.

The finished body is painted in our color scheme and fit to the car.  We can replace most panels in minutes and can replace the most difficult panels in about an hour.
