On long highway trips, I put the car in tour except for the exhaust, which I put in stealth. In stealth, the exhaust is a quiet as a C8 stingray in tour mode. Tire noise is the bigger issue. The Z06 has more tire noise. I didn't notice an increase in tramlining over the stingray on the highway in general, although in some places I have felt it.

I definitely notice tramlining on my C8Z with Cup2R tires.

Tires make a big difference, with newer street Michelins being much better. The Michelin PS2s that came on the widebody C6s had a lot of tramlining, the follow up tire model (SuperSports) were noticeably better but still had some tramlining. The Michelin A/S3+ almost completely eliminated it. This was all same size tires/wheels across two different C6s (GS & ZR1). I'd expect any of the Michelin Cup series tires to tramline a lot as they are essentially race tires that happen to be street legal.

based on my experience it Is 100% true. I have the 23 z06 with z07, 23 z06 and 22 stingray and that is the order of traming most to least. I drove all 3 on different days to the track, round trip on the road about 300 miles. most comfortable stingray, z06 then z06 with z07.

Is the trimming that noticeable on z06?

My C8Z doesn't do it as much, very rarely, on the PS4 tires.

My C7Z when it came with the stock PSS run flats, did it a ton. I have the michelin AS3+ on the car now, old school AS tire and i don't notice it at all.

I wouldn't call the A/S3+ "old school", if I remember correctly they were the generation after the PSS, and honestly from my experience were very close to the same performance as the PSS. But your point is valid, in general the more performance focussed the tire, the more likely it is to have some negative behavior (i.e. tramlining). The PS 4S is amazing because of how good it is without having any significant negative behaviors (other than cracking at sub 20F).

Every "Current Drive AVG MPG" has been under 9 MPG besides delivery day when I drove from Missouri to Texas all highway driving for 1000 miles in Auto, 500 of them being break in miles.

I only say old school because there's a newer all season 4 tire. Plus i believe i got those AS3+'s back in like 2019 or so but i think that tire debuted in 2014 or so lol.

I just got mine out for the first time in a couple of weeks. I love touring plus auto mode until I get somewhere fun, then sport/manual/paddles. Or just when I feel like either for whatever reason, that’s the great thing about this car, great cruiser and of course great when in angry mode.

Just drove home my 3lz htc. Traded my 2022 3lt htc for it. Considerably louder than my 2022. Car seems to want to go. Suspension is definitely stiffer in tour mode as compared to tour mode in the 2022 I had which was z51. They also changed the whole information system. So need to figure that out. Dealer just handed me the keys and assumed I knew the new information system. I will figure it out

Anyone have a video on the new information system? Steering is noticeably quicker. Just my initial 30 min drive home impression. Feels quicker and more responsive even though I really did not get on it all. Like a tiger ready to pounce.

congrats on the new ride!

In a few hundred miles you'll be use to the suspension feel. I now use sport almost all the time.
