Callaway has a German branch that’s called Callaway Competition. It has just turned 25 years old, and to celebrate this, it is putting out a special 25th Anniversary Edition of the Callaway Corvette SC757 based on the C7 Corvette Z06. The company plans to build only 25 of the cars and each buyer will have to supply their own donor car for the build. The SC757 package that the new anniversary car will be built on came out in 2015. It pumped up the Z06’s supercharged V8 engine from its stock 650 hp and 650 lb-ft of torque to a whopping 757 hp and 777 lb-ft of torque.
