Radiator Upgrades

The best solution is for sure the radiator upgrade for starters.

Yes Kind Of!

So short story yes, long story is it depends. The 2015-16 Corvettes faced overheating challenges. This was caused by insufficient cooling and heat soak. GM faced class action lawsuits and did what they could to mitigate the problem with upgrades to later models. We have included details in our Upgrade Page here: https://www.corvette-web-central.com/c7-z06-performance-upgrades.html

The ones GM implemented on 2017-19 Z06 Corvettes were the improved Supercharger Lid and increased radiator cooling capacity. We also think its a good idea to upgrade the intercooler but GM never did that in the 17-19 Z06 models.

Realizing the error of their ways GM upgraded the body aerodynamics on the ZR1 and enlarged the radiators and cooling capacity of the limited production 2019 ZR1. As far as we know the cooling issues that plagued the Z06 is not an issue with the ZR1. If you have a ZR1 please chime in!

We suggest larger radiators and coolers with the SC Lid upgrade first then look into the front bumper for the ZR1 to improve airflow into the front of the car.
