Default Stingray HTC performance questions

Hi everyone, I have a 2024 Stingray HTC without Z51 and mag ride. Three questions for this group:

1) does anyone have a link to a video (worth watching, as Ive seen a few on youtube that didn't provide what I am looking for) that clearly shows the difference in handling between a C8 stingray Z51 and non-z51. Basically I want to know how much handling Im missing. Bonus if the video compared an HTC with z51 and mag ride against an HTC nonZ51 and mag ride
2) Someone in the Facebook group said the C8 HTC is governed at a 155 mph, is there a way to confirm this?

3) Someone in the Facebook group said most tracks in the country do not allow convertibles, is there a way to confirm this?

Thanks in advance

Tracks may limit soft top convertibles but far no problem on Hardtop like C8

I have a 2022 HTC without Z51 and mag ride. From personal experience I can say they (2022 models at least) are not speed limited to 155 mph.

Wow. Don't know where you're getting your info from. I've never heard of a Vette with a speed limiter. I can assure that the car goes at least 187. Probably more.

As far as handling? Why? Sure there will be differences but unless you track the car I doubt you'd ever notice.

The C8 HTC is limited to 155 MPH with the top down. When it's up, no limit. Also, no problem doing track days with the HTC and the top up. The steering will be tighter and more precise with the Z51 over the non Z51 car.

Interesting. I did not know that. Never tried it with the top down. I guess cuz it get's a bit breezy.

Anyway, good answer! Good Answer!

#1)
There is no real way to quantify a performance difference in a chassis setup aside from loose vs tight. Or totall stiffness by way of roll couple. It sort of depends on how you like a car to be setup. Without getting into a subjective by the seat of the pants guessing game, you can evaluate it this way. The z51 is as a matter of fact much more capable than a non z51. The cooling is a few orders of magnitude better infact enough to be noticable on the temp gauges throughout all driving loads. Next mag ride is superior to a passive damper because it can change it's stiffness and allow for different performance profiles. This can allow for more car control for a known driving profile (in our case low aero hpde car). Then it can allow for more mechanical grip and a tighter ride for around town.

#3)
Lots of tracks and the organizations that run HPDEs allow convertibles. Some may require a roll bar, I know 991s and 992s have a pop up roll bar and it is actually recommended to run with the top down so if you hit a bump too hard the pop up bar doesn't shatter your vert glass. Some tracks / organizers will disallow convertibles but that is not as common.

I found out by accident. We were on a spirited drive and I had the top down, then all of sudden I hear a bunch of chimes. My first thought was, Uh Oh, something’s wrong, like DCT failure. I look down at the DIC and it says Speed Limited to 155 with top down. I was very relived to see that’s all it was!

I'm curious about this topic also. What's the difference in the cooling systems. But more than that, how much difference is there between a Z51 and a non Z51 with mag ride?

Go drive a car with and then without magride. The feeling will be subjective. However the z51 has better braking, cooling, and suspension. *Note that the non magride car will ride more harshly than magride since the passive dampers are valved between sport and track settings on a magride damper.

There was one thread here on one of the larger tracks that refused to let a HTC run saying the nacelles aren't structural support. Don't remember what track or what organization but I recall reading the thread. Very rare but has been reported on this site at least once.

HTC's are allowed at all the track events I have been to in north east.
