The Diablo SE was built for GT-championships, which is why it was built with the Jota upgrade kit. Much weight was saved in the design for this vehicle. The side windows were replaced by synthetic glass and only a small portion of them opened by turning a knob inside the door,.
In 1999 Lamborghini decided to upgrade the original Diablo and re-named it the Diablo GT. Some of the changes that were made to the vehicle were made to create and enhance an aggresive style with features that would improve handling and perform top speeds. Lamborghini made a bold claim stating that they were creating the fastest car in the world and decided to make only eighty of them. This of course peaked enthusiasts curiosity and made it more appealing to them.
