Lapel Pin, Callaway 25th Anniversary
Die Struck, Brushed Metal Lapel Pin commemorates the 25th anniversary of the Callaway Corvette. The first generation Callaway "Twin Turbo" Corvettes were built at Callaway's Old Lyme CT facility under contract for Chevrolet Division. The RPO B2K was the first time a Regular Production Option designation was applied to a Chevrolet vehicle that was prepared external to GM facilities. Over 500 Callaway Twin Turbos were built during the 1987 to 1991 model years and sold by Chevy dealers worldwide.

When Chevrolet made the transition from L98 engine to LT1 engine in 1992, management decided that the ZR1 would become the top-line Corvette, avoiding the turbo system retooling expense. The Callaway Corvette lived on, however, now designated Callaway "SuperNatural" Corvette with added displacement and internal engine modifications replacing turbocharging to provide increased performance.

During the C5 Corvette era, the Callaway Corvette evolved into the Callaway C12, with a race car variant winning pole positions at Le Mans and world-class supercar in road configuration. Callaway engineering was also busy with its development contracts for Aston Martin, Land Rover, Mazda and Holden (GM-Australia) during this period.

By the time the C6 Corvette was introduced, Callaway was ready with SuperNatural and SuperCharged Corvettes. The supercharged SC-series ultimately replaced the naturally aspirated models, offering significantly more bang for the buck. Over the years since 2005, Callaway has added new standard and optional equipment and applied numerous refinements to the Callaway Corvette, culminating in the current SC606 and SC652 models.
