If you concerned about not getting your hands on the a Corvette ZR1, due to high demand and model shortage, GeigerCars may have an answer for you.
“The company tinkered with the Corvette Grand Sport and was able to boost it up to near-ZR1 levels.
First of all, GeigerCars installed a 6.2L V8 engine on the Grand Sport. This boosted the car’s power from 430HP to a tantalizing 588HP on the tracks. This definitely made it possible for Gieger GS to hit the 60-mark in less than 4 seconds. It might not be quite as fast or powerful as the ZR1 supercar, but 639 horsepower and a 3.3 sprint are certainly figures worth boasting about.
You can purchase the car with a supercharger for only €16,450 and modify its transmission ratio for €2,800.”
