4. Callaway Super Speedster LM
Callaway had much success in the ‘80s with their version of the Corvette C4. They gave it a heavily turbocharged engine to deliver ridiculous performance numbers. However, Reeves Callaway wanted to go racing, so in the early ’90s, they unveiled the Super Speedster LM. It was the ultimate version of a race-prepared Corvette C4 with a turbocharged LT5 V8 engine with 766 HP on tap. However, this was much more than just a highly-tuned Corvette.
Best of all, the Super Speedster LM had numerous body modifications, a totally revised suspension, race brakes, and much more. These are the fast and fantastic but forgotten supercars of the ’90s. Most are obscure and rare machines you probably will never see on the street. However, if you’re lucky, you may see one of these beauties in a museum or at a car show. Limited in their numbers, these cars have quickly been forgotten.
