Geiger said they'd have the car in Frankfurt, but we somehow missed it. While the press release makes no mention of suspension tweaks, Ultraleggera O.Z. Racing wheels replace the GM originals, with the 10 x 19 fronts and 12 x 20 inch rears shod in 285/30ZR19 Michelins at the bow and 345/25ZR20s astern.Geiger is back, and this time it's the vaunted Corvette ZR1 that gets the tuner touch. Dubbed the "Geiger GTS," this über ZR1 doesn't offer ridiculous power gains over its stock bruder, just some careful tweaks that net an additional 63 hp. Still, that brings the already prodigious power up to 710, with a similar bump in torque from 607 to 677 ft-lbs. That's good enough to register 3.6 seconds for the 0-100 km/h sprint, and a V-Max of 212.5 mph.
