1991 Callaway Super Speedster LM
Offered from the original owner’s collection, this 1991 Chevrolet Corvette Callaway Super Speedster LM is the second of only two so-called Series II Super Speedsters based on the ZR1 model.
The offspring of collaboration between Corvette performance guru Reeves Callaway and designer Paul Deutschman, the Super Speedster LM is an astonishing step up on the original Speedster, taking full advantage of the ZR1’s Lotus-engineered, all-aluminum DOHC engine and 6-speed manual transmission. One of only three twin turbocharged and intercooled LT5 engines built by Callaway, it delivers a pavement-shredding 766 HP, making the car the most powerful of all the twelve Speedsters produced by the company.
More than “just” an incredibly well-engineered engine swap, the Callaway possesses engineering modifications to the suspension and driveline that fully complement its massive power output. The Le Mans body is the only one used on a Speedster. Designed by Paul Deutschman, the Super Speedster LM is a unique combination of his brilliant Callaway Speedster and the dramatic and aerodynamically efficient Le Mans GT2 pole-winning Callaway LM racer. Luxurious appointments abound in the LM’s interior, which features the consummate craftsmanship of Johann Merkhofer.
Lavishly finished in leather and suede with specially embroidered seats, it is fully equipped with comfort and convenience features that include air conditioning and Delco Bose stereo with CD. Unique among Callaway Speedsters is the car’s removable double-bubble hard top, which shares the car’s gorgeous Candy Wine Red paint and evokes the closed-cockpit C7R racers.
