T-top

nounStandard termAutomotive

A vehicle roof style featuring two removable glass or solid panels separated by a central structural bar.

A roof configuration consisting of two removable panels above the driver and passenger seats, leaving a rigid longitudinal bar running down the center of the roof from the windshield header to the B-pillar roll hoop. This design offers an open-air driving experience similar to a convertible while maintaining greater structural rigidity and side-impact safety.

Heard on the job

Check the weather stripping on that T-top, because they're notorious for leaking right above the seats during heavy rain.

Insider tip

The structural integrity of a T-top car relies heavily on the central bar and floor pan. High-horsepower modifications can actually twist the chassis enough to crack the glass panels if subframe connectors are not installed.
