The kids at Geiger Cars have been busy. Aside from rolling out one wicked Ford GT, the company has also been tweaking on the meanest Cadillac of them all – the CTS-V. The company managed to tweak the 6.2-liter LSA from its stock output of 564 horsepower to an unbelievable 619 ponies. The tuner kept the stock 6-speed manual transmission, but clipped fifth and sixth gears ever so slightly. So just how fast is this four-door? Geiger says the mad Caddy can roll all the way up to 205 mph. Damn. Check the gallery for more shots. [Source: WCF]
