The 2019 C7Z06 is when they added some ZR1 upgrades.

I had a 2019 C7Z06 and it was definitely a fun car. The only thing I miss is being able to buy an Akrapovic Titanium exhaust. Other than that, I feel that the Corvette didn't give as much confidence as a stock manual transmission (I switched to MGW which was amazing), and adding power. The weight of the car and width of tires made the car wobble a lot on even small cracks in the road. The power adders really made the car tail happy as well even with Toyo R888R's.
