Re: Convertible drag cars
Verts are heavier and top up or down, have more aerodynamic drag. Sorry, no specs to provide.

Re: Convertible drag cars
I thought the same thing, but a previous owner of my '92 T/A convertible had installed a line lock on the prop valve in addition to more wiring that I am still removing from the car.

Re: Convertible drag cars
The weight difference isn't much. That hatch glass is heavy and the chassis stiffening is pitiful.
And your center of gravity is ever so slightly lower.

Re: Convertible drag cars
Agreed. The connectors on these cars are riveted on and maybe 1/8" thick. The convertible top, tonneau cover and trunk lid probably make up for the weight difference of the hatch and top or T tops. Convertibles are rarely seen as drag cars because they are much more rare in the thirdgen population (driving up their cost) in addition to having the most chassis flex.
