FABRICATOR (tin man, metal hanger)

These are the guys that hang the bodies on the race cars. They are skilled craftsmen. All Cup cars must undergo rigid inspection and at last count over thirty templates are used to make sure that the race cars meet the specifications of the rule books. If a fabricator doesn't do his or her job just right then the car won't pass inspection and has to be rebuilt. This does not please the crewchief (owner, driver, rest of the crew etc.)

FIREWALL

A solid metal plate that separates the engine compartment from the driver's compartment of a race car. This is a very important component of a race car. It keeps all the hot fluids and the occasional fire outside of the "greenhouse" or driver's compartment.

FRONT CLIP

Starting with the firewall forward. It is literally the front half of the car and can be unbolted from the body.

FUEL CELL

This is the gas tank of the race car. It is about as high tech as you can get. It is a metal box that contains a tear proof bladder with foam inside. It is designed to flex during a crash but not to rupture. It has a check valve in the spout in case the car rolls over so the fuel is not spilled out. Its whole purpose is to contain the fuel and keep it from catching on fire in the advent of a crash. NASCAR has very rigid specifications on how fuel cells are manufactured and installed.
