See what makes up a NASCAR Sprint Cup Series car

1. Radiator Air Intake

Directs outside air into the radiator to cool engine fluids.

2. Brake Air Intakes

Direct outside air to brake discs and rotors for additional cooling.

3. Hood Pins

Four, quick-release metal pins with wire tethers that keep the hood closed.

4. Cowl Induction

Housing for the air cleaner that connects the air intake at the base of the windshield to the throttle body.

5. Body Panels

Fabricated from 24-gauge/0.0247-inch (minimum) cold-rolled sheet metal.

6. Roll Cage

A cage of steel tubing inside the car that protects the driver during impacts and rollovers.

7. Jack Post

Where the jackman places the jack to lift the car during pit stops.

8. Double Frame Rail and Energy Absorbing Material

A combination of steel plating and foam-like, energy-absorbing materials installed in between the roll cage door bars and door panels that attenuate energy upon impact.

9. Window Net

Safety device located in the driver-side window that keeps the driver's head and arms inside the car during an accident.

10. Roof Strips

Two three-quarter-inch-tall aluminum strips that run lengthwise on the roof to help prevent the car from flipping when turned sideways during a spin or accident.

11. TV Camera

Allows NASCAR fans to view the racing from the driver's perspective.

12. Roof Flaps

Help prevent the car from becoming airborne when it is turned sideways or backward during a spin or accident.

13. Jacking Bolts

Area where the crew uses a tool to adjust the handling of the car by altering the load on the rear springs.

14. Cooling Vents

Help remove warm air from the cockpit and help cool critical components inside and at the rear of the car.

15. Goodyear Eagle Racing Tires

Treadless radial tires designed specifically for racing.

16. Rear Deck Fin

At 3.5 inches tall, it can be the full length of the deck lid (25 inches) but must be a minimum of 17 inches, starting at the front of the deck. This tuning tool adjusts rear sideforce and is made of clear polycarbonate.

17. Rear Spoiler

Directs air flowing over the rear of the car, providing downforce to improve the handling.
