Answer is 66.9mm. That is down from 2019 center hub bore of 70.3 mm.
Here is the info I have been able to gather:2020 Z51 wheels are 19x8.5 +52mm and 20x11 +64 mm.
Bolt pattern is now 5 on 120mm (not 120.65mm) and stud is increased from 12mm to 14x1.5mm. Center bore is 66.9mm

The 2020 Corvette part number is 84448918 (not 84449818 which I think is a typo). These do NOT fit the C7. They fit the following vehicles:
- 2020 Corvette
- Chevrolet Camaro 2019-2020
- 2020 Cadillac CT5
- 2020 Cadillac XT4
- 2019 Cadillac XT4
- 2020 Chevrolet Camaro
- 2019 Chevrolet Camaro

Shopchevyparts, Black Lug Nuts (part #84448918) $146 + $10 for shipping = $156.
Wildhammer $174
Shopchevyparts.com also had the best price by far for engine covers; $371. I bought it now to paint the logo while I wait for the car to be built.

I have used the Precision brand lug nuts from Amazon on many of my hot rods and the quality has been fine. $22.43 for 14x1.5 mm

Hey, if you torque 'em to 150 ft lbs and the finish is high quality, that's a bargain.

We'll have to see what the C8 lug nut torque spec is, but for the C6 and C7 it was 100 lb ft.
