We highly recommend you prioritize your first upgrades to be on the cooling system. The C7 Z06 can be prone to overheating for the earlier model years. Update your radiator first before you do anything else! Especially if you have 2015-16 models. The 2017 model corvette implemented factory solutions to mitigate the overheating risk.
Why you ask?
Corvette engineers admit to missing the mark for the cooling needs on early Z06 Corvettes. They claim that adding performance upgrades compounded the issue of inadequate cooling, so we suggest cooling upgrades first.

C7 Z06 Performance Upgrades | By Chris Trautman
So, a little info you may or may not know, some C7 Z06 Corvettes have overheating issues when used in high power demand applications. Most owners will not experience this unless the car's cooling system gets massively heat soaked with hot weather and track-based high-speed/load events.
The C7 Z06 was engineered with a "pro driver @ 86 degrees" design standard for all performance development. The philosophy had proven to work well for GM for many years. After a few years, GM realized that owners who drive their corvettes on tracks in southern warmer climates had issues overheating and consequently going into reduced power modes.
The first generation of Z06 Corvettes (2015-2016) have the majority of the issues. On 2017+ Corvettes GM attempted solve the overheating problems, and many companies have come to the rescue with Cooling Upgrades for the C7 Corvettes that came without the extra cooling or those that require additional upgrades.
We cover the details of all the fixes below..........
1. Option 1 - C7 Z06 Radiator Performance Upgrade..........
The number one thing GM had to do to fix the cooling issue was to increase the size of the radiator on later generations of the C7 Z06 Corvette. More volume equals better cooling efficiency. For the rest of us, early Z06 owners (our selves included) require us to upgrade on our own. The first radiator in this section has a higher price point and may work better in extreme situations.
2. Option 2 - C7 Z06 LG Motorsports Radiator Upgrade........
LG Motorsports makes some of the best performance parts you will find for your C7 Corvette and they were one of the first to offer cooling upgrades for the C7 Z06.
3. C7 Z06 Intercooler Upgrade..........
This little radiator cools the coolant in the Supercharger air to water intercooler system. For maximum performance we suggest upgrading to increase the cooling capacity of your intercooler and thus decreasing the intake air temperature which increases the air density and also increases the horsepower potential of what your engine can produce.
Wrapping your exhaust manifolds reduces under hood heat as well as removes heat transfer into the engine oil cooler near the driver side.
DEI is a well known solution in the C7 Corvette and performance world at reducing unwanted heat transfer. Check out their Titanium manifold wrap here.

He has owned three Corvettes over the last twenty years and does not plan to stop owning one anytime soon.
