Pro Street '72 Camaro on the dragstrip

**Pro Street**, also known as a **back half** or **tubbed car**, is a style of [street-legal](/source/Street-legal_vehicle) [custom car](/source/Custom_car) popular in the 1980s, usually built to imitate a [pro stock](/source/Pro_stock) class race car. Pro Street cars are close in appearance to cars used in drag racing while remaining street-legal and with a full interior.

Cars of this type typically feature two of the following three modifications:

- A highly modified [V8](/source/V8_engine).

- A narrowed [rear axle](/source/Rear_axle) coupled with oversized rear wheels & at least 14-by-5-inch (36 cm × 13 cm) sidewalls (located within the wheel wells) for maximum grip and wheelie bars.

- A [roll cage](/source/Roll_cage).

Aside from the rear suspension and wheel wells, cars of this type often remain unmodified past the firewall, keeping stock floorpans, a full interior with windshield wipers, carpet, and working lights.
