When Dick Guldstrand introduced the GS80 series in 1986, the car was targeted specifically at Pro-Solo and autocross enthusiasts. He knew all about the needs of these groups, as he was a longtime provider of performance upgrades for the C3 and a direct supporter of a small team of racers from the Western Council of Corvette Clubs. Up to this point, Dick had basically been a tuner. With the intro of the GS80 he was venturing into the realm of small-volume manufacturing.
When Chevrolet changed gears to the LT1 engine, Callaway revealed their new SuperNatural line and the CR1 based on the ZR1’s LT5. Options for the CR1 included the radical Aerobody, German upholstery and special wheels, brakes and exhausts. The CR1 used a larger displacement to produce either 475 or 490 bhp.
Based on the Corvette Z06, this new GTR also represents a collaboration between Specter Werkes and Lingenfelter Performance Engineering, with a Lingenfelter twin-turbo system powering the car – and pumping its 7.0-liter LS7 engine to 800 horsepower. Featuring dramatic bodywork and carbon fiber details, the GTR blends racing-inspired design cues with uncompromising luxury and performance.
1997 Callaway C12 Corvette Silver
Callaway has built a firm reputation for producing some of the most sophisticated and advanced Corvette-based automobiles. Introduced in 1998, Callaway’s C12 continued this proud legacy. Designed, developed and constructed by two top German engineering and development companies, Callaway and IVM, the C12 was intended as a bespoke, high-performance car that offered its occupants a civilized interior and relaxed ride. One of the most respected Corvette super-cars ever.
Reeves Callaway has always had a dream of competing a Corvette of his own at the 24 Hours of Le Mans, France. The idea begin with the body work for a street version, but one thing led to another, and a full race version was completed as well. The street version is almost identical to the race version because the hood, tail, rocker panels, and lower door halves, are all made of carbon fiber, just like the race version.
The Callaway C16 was Callaway’s 16th major automotive project. It was a limited production, bespoke automobile, built to order, by what the Press called “the best specialist engineers in the business”. These cars are seriously fast, beautiful, and exclusive. The C16 was a direct competitor for the Porsche GT3, the Lamborghini Murcielago, the Ferrari 599 GTB. It was both faster and more capable than its competitors, at less cost.
The Zagato company took a C7 Corvette Z06 and transformed it into the IsoRivolta GTZ, a "spiritual descendant" of the Iso Grifo A3/C (Corsa).  The original A3/C race car was developed by Giotto Bizzarrini not long after he left Ferrari, where he had served as cheif engineer behind the 250 GTO, which is revered as the world's most expensive car.  Bizzarrini purportedly fancied the A3/C as his "own personal evolution of (and improvement upon) the GTO design."
