well ironically, GM did seem to learn "some" lessons from previous generations. Like my car operates fine without TPMS and it doesn't seem to care about tire diameter as much when the "nannies" are still on.
Hopefully they'll add a provision to disable mag ride without having to resort to simulators and software tricks.
There is some minor electrical dumbfuckery, like my eLSD won't function after turning the car on after the kill switch it turned back on, I have to turn the car off and back on again. (I store the car with the kill switch off)
Not having steering wheel buttons has pushed me to get an AiM MXP logger as I am unable to see 75% of my gauges due to all the errors/popups but that would be a non issue had i just kept my stock steering wheel.
So, I think people will be able to take the C8 pretty far as a race prepped car. I am curious to see how harnesses are gonna be crammed into the cockpit of the C8.
