Some C7 Z06 owners, especially with early cars on hot days, report the car reducing power or showing high temperature warnings after a few hard laps. The supercharged LT4 creates a lot of heat. GM made changes to later cars, and the aftermarket offers cooling upgrades.

From the C4 onward, Corvettes have many electronic modules that draw small amounts of power with the car off. Add aging batteries, aftermarket accessories, or a module that doesn't go to sleep, and the battery can go flat in days or weeks. Storage without a maintainer is the most common cause.

Why C5 balancers are replaced, how to spot a failing one, and what the job involves. This is an overview, not a step-by-step procedure.
