This thread covers a wide range of C8 component areas and colors, but Jeremy and I wanted to insure you knew this information as soon as possible as your figure in your future purchasing plans — or just as things of interest.
Today’s Jag Learnings:
As confirmed this afternoon by Jag in the NCM “Expo C8” event, he wanted to share the following factoids, separate from his two videos he is currently completely and wanting to post later this evening.
A) The Heads Up Display (HUD) is not included in the 1LT package, but again like the C7, is standard/included if one were to get a 2LT or a 3LT. The HUD system is better integrated into the electronic and communications system of the car, had better, clear images, and displays more information — including the much requested turn signal inclusion option.
B) The mid engine Corvette has moved from the C7’s 50% front/50% rear weight distribution, to now having a 41% front/59% rear weight measurement. This is the same range at all ME Ferrari’s, all McLaren’s, all Lamborghini’s, and even Porsche’s (the 2019 Porsche 911 has 60%). As dcbingaman noted in a recent post, moving the weight to over the rear wheels results in better accelerative traction.
C) Fear not any longer, those of you who have had so much angst about the C8 going to have a start/stop system. It has nothing like that system.
D) While the C8 has many more safety systems, it will not have adaptable cruise control for the 2020 model years. It adds into it safety equipment what we have earlier believed, blind spot protection. It has five cameras to assist in your safety .
E) Passenger cabin space: The “fish eye” lens that shows the driver’s side of the cabin, results in a “oh my the passenger side is so squished” for a few folks I talked with. So to insure it was not, Jeremy sat in the passenger side of the cabin today, to test/confirm that there is adequate “footwell” and other space, and also importantly that is far from a “confining feeling space.” I did the same for the driver’s side last night. We did this to refute some of the earlier and accurate comments that some exotic ME’s hav had limited footwell space.

Separately, last night I became educated about the following:
A) The C7 jacking puck works perfectly for the C8.
B) The lug bolt size has increased from the C7’s 12MMX1.25MM to 14X1.5MM (as we expected since the Camaro ZL1 1LE did). As a consequence, the C8’s wheel holes that surround the lug nuts, had to have their inside-diameter be increased. [At its test facilities and at BGA, GM uses heavy duty torque impact wrench’s with thick-wall sockets, so we will be fine removing the C8’s wheels.
C) There is no Z-51 spoiler delete option. When I asked Harlan to explain this a little further, he noted that with the major Z51’s splitter, the car was well balanced with the combo wing/regular spoiler on its rear deck (the one we have been seeing for a long time, thought sometimes with its sagging pool noodle).
D) Not only did Tadge announce during his last nights part of the reveal presentation that the seat back travel is over 1”, but also the seat cushion to bottom of coupe roof is increased by that same +1” amount. I also confirmed that the distance between the door armrests is greater on the C8 than the C7.
E) In talking at length the comparisons of the GT’s three seats, the GT1, the GT2 and the Competition Sport seat, just as in the C7, the Competition sport seat has much firmer foam. While fine for some, not for others. GM recommends that those who do considerable length trips, especially if they do not track the car, get either the GT1 or the GT2 seat. They realize that some bought the C7’s comp seat primarily for their beautiful upper back visual carbon fiber “butterfly.” Hence they wanted to offer the user who wanted that visible CF look, a softer foam seat option.
F) Talking colors:
1) Specifically about brake calipers, as I learned for the C7 when I talked with Brembo’s Chief High Performance Engineer, the C8’s brake calipers are not a perfect color match with their corresponding exterior body panel colors. Notice how different this is for the Accelerate Yellow body paint and the yellow green (IMO) paint caliper. [Please see the official GM picture below.]
2) Re the new two tone Twilight Blue/Tension Blue interior option, while the two interior designers I talked together with both, when I pushed a touch, said that this interior could go with Elkhart Lake Blue; however, that two-tone interior was specifically designed for excellent matching with the new Rapid Blue.
3) Morello Red interiors pioneered in some ATS-V and CTS-V limited editions.

We get Morello Red for the first time in the C8. Like “Natural” it is a “dipped color — meaning it covers almost all of the interior’s panels (as opposed to being a regular interior color that share itself with some black panels).
E) Notice that to get black wheels in a 5-Trident Spoke pattern, one must buy them from the dealer (they are not factory order-able). Interestingly, the 5-Open Spoke wheels can be factory ordered.
