SEMA’s orgy of awesome kicks off next week, and the trickle of previews we’ve been seeing has turned into an all-out deluge. Check out what Corvette tuner Specter Werkes is bringing to the part – a reworked version of the C6 GTR we saw last year. The car gets its grunt from an LS7 with not one, but two turbos cooperating for a final horsepower figure in the 800 range. Throw in the wild body work, wicked paint and brakes from StopTech and you’ve got a serious machine all around. Hop over to our gallery for a closer look. [Source: SpecterWerkes]
