The C7 Corvette Z06 was originally offered as a track-ready performance monster, but unfortunately, the factory cooling system isn’t up to task when it comes time to throw down some hot laps. GM was even sued over it. Now, however, U.S.-based tuner Callaway Cars Inc. is offering a heavy-duty upgrade to address the issue.
Developed in a collaborative effort with German partners Callaway Competition and Tikt Performance, the new C7 Corvette Z06 cooling upgrade is offered in two consecutive levels to meet the needs of customers. Level 1 includes a carbon fiber grille surround with a laser-cut Callaway grille insert that fits to the front bumper, as well as a high flow-rate intercooler pump that flows 35 percent more than the factory Z06 intercooler pump. The Level 1 upgrade also includes a high flow-rate thermostat assembly with a CNC-machined housing anodized in Callaway Blue and high-flow thermostat, as well as increased intercooler system capacity.
Callaway says the Level 1 kit is “ideal for spirited road driving, for autocross or for high-speed open road racing events.”
The Level 2 upgrade takes things up a notch by adding a new carbon fiber front splitter, complemented by a carbon fiber front undertray with integrated brake cooling channels. The undertray extends all the way to the front subframe. The Level 2 kit also includes a new air-to-oil heat exchanger that replaces the factory unit and mounts between the new splitter and undertray. Finally, the kit adds lightweight Hi-Temp polymer braided -10AM oil cooler lines with a CNC-machined thermostatically controlled adapter housing.
Callaway says the Level 2 kit enables “full track day sessions to be driven by an expert driver without encountering limp mode,” and adds that the new aero components “provide considerable aerodynamic improvement, shifting balance to reduce understeer.”
The new parts all look to be of a very high quality, and add a tasty bit of composite styling to the C7 Corvette Z06 front end. Pricing for the Level 1 kit is set at $10,995, while the Level 2 kit is $14,995.
