2009 Corvette SV 9 Competizione

As early as the late 1990's, San Francisco based coach-builder SV Motor Company envisioned a car that took the raw performance of a Corvette and refined it with a touch of Italian flair.  Their vision was to infuse many of the design elements found in the Alfa Romeo 8C Competizione (from which the SV 9 clearly drew its inspiration, as well as its name) with a 2009 Chevy Corvette.

1992 – 1996 Callaway SuperNatural Corvette

Chevrolet's introduction of the LT1 in 1992 as the base engine in the Corvette phased out the L98 based Callaway Twin Turbo. Previously, Callaway Corvettes made their increased power through positive manifold pressure; now they made it through increased displacement and finesse. Initially called the CL1 or CR1, they designated the chassis they were built upon. They were based on the pushrod LT1 cars (CL1) or the 32 valve DOHC LT5 ZR-1 cars (CR1).

1994 Guldstrand Grand Sport 90 (GS90)

As the story goes, when the Corvette ZR-1 came out in 1990, Dick Guldstrand saw an opportunity to create his vision of the perfect Grand Sport ride, instead of his name just getting slapped onto another Chevrolet product. He asked GM for fifteen ZR-1’s and some money. He got one car and permission to do whatever he wanted to do with it. And that’s exactly what he did. Called the "GS90", Dick's car would prove to be the most elaborate and expensive specialty Corvette ever built.
