Pro Street, also known as a back half or tubbed car, is a style of street-legal custom car popular in the 1980s, usually built to imitate a 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.
A narrowed rear axle coupled with oversized rear wheels & at least sidewalls for maximum grip and wheelie bars.
A 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.
