Reiter Engineering used last weekend's 24 Hours of Spa race to reveal its Murcielago LP670 R-SV, a GT1 race-ready version of the already hardened LP 670-4 SV. The box-stock Lambo already shed 220 pounds compared to its non SV brethren, weighing in at 3,451 pounds. The Reiter racer, stripped of any non-essentials and with a body rendered entirely in carbon fiber, drops further 921 pounds to weigh in at just 2,530 pounds (1,150 kg).
Reiter is hoping the car will be one of the six allowable brands chosen for next year's FIA GT World Championship. You can read the press release on the taurean missile after the jump, and check out the gallery of high-res photos below.
