The Diablo was Lamborghini's flagship V12 supercar during the 1990's, succeeding the Countach, and during the late 90's was sometimes seen on the circuit. It was at the Geneva Auto Show in 1999 when Lamborghini unveiled the race ready Diablo GT, limited to just 80 units and ready for the track including a top speed of 340KM/H.
It was thought that this was the ultimate Diablo, but at the Bologne Motor Show in that very year an even crazier Diablo was unveiled. Limited to just 40 units, this new Diablo was not street legal in Japan or the USA and was known as the Diablo GT-R.
As soon as it was unveiled teams were already lining up to use it in the SRO Lamborghini Supertrophy, and was seen as the true successor to the 1996 Diablo SVR with full race aero even in street form, as well as a 600HP 6.0 V12, compared to the 580HP seen in the Diablo GT.
A true race oriented chassis was created, this time with a fully integrated roll cage and a massive rear wing that was actually directly bolted onto this lightweight chassis, while the brakes were again upgraded to racing spec Brembos.
Thanks to the 600HP V12, the GT-R was capable of 350KM/H (220MPH), even with that huge rear wing, with the car running a 5-Speed manual gearbox. The wheels were also specially designed to take both standard road tyres and Pirelli racing slicks.
On the inside the Diablo GTR was also stripped of all unnecessary items, the air conditioning was gone while the passenger seat was also removed and the driver seat was now a light-weight Carbon-Fibre bucket seat with a six-point racing harness.
The standard buttons were replaced by racing switches, while an obligatory fire extinguisher system from Momo was mounted on the right side of the cockpit with the option of turning it on with a button located on the central tunnel. Also the already custom steering wheel of the Diablo GT had been replaced by an even lighter race-type unit.
