You would think with all the computer tech, they could make the base car and those with the Z51 ride identical in tour mode. In sport mode, the Z51 might begin to show its differences a little and in track mode (stiff and sensitive to poor roads, but ideal for a smooth track), it would be more noticeable.

I watched the jay Leno garage episode with the C8 vert today. Very intriguing. Seems to me the fixed roof would suffice for track days - it’s no different from the coupe structurally. And adds 80lbs. So that gives you 3 cars.
track car. GT and convertible.

I could replace my Panamera and my 6th gen Camaro SS vert with one and pick up a track car in the deal.

Am I missing anything ?

preciously I had no interest in the C8 at least not in the short term. Sure eventually it’s bound to happen.

^ I watched the episode too, but i'm not so sure about your interpretation. Structurally the coupe is different because of the contiguous solid halo. You may however be able to fool some of the track gate keepers when the vert top is in place, but I'm sure most of the keen ones will know its a convertible.

Your logic is correct.

1. The C8 HT vert is formally HPDE approved by NASA. I championed the cause - https://www.corvetteforum.com/forums...post1600285454

2. The car is designed to utilize the windshield frame to support more than 2X the static load of the car (dynamic loads could be much higher, but at least it's something). The structure behind the driver under the nacelles is not what got it approved. GM confirmed the vert meets all the roll-over tests of the coupe via the windshield frame and NASA approved the car. There is some structure behind the driver that will help, but the windshield frame does the bulk of the work in both coupe and vert.

Spring rate ultimately determines ride. The base car has the softest springs and will have the worst performance on track. The magic of the magnetic shocks is they can add "spring rate" with the shock tech. So the Z51 with mag ride (FE4) has softer springs than the Z51 FE3. They then make up for it with the shocks. This allows you to have a grand touring ride in tour mode and a trackday stiff ride in track mode.

Obviously ,I haven’t driven nor lapped a C8 yet...
The only issue I see with the base suspension car for track duty is that it comes with the all season tires,that’s a guaranteed penalty....
a softer set up is a non issue for me.

It'll be fine for casual lapping days, but if you're into the HPDE hobby it won't be the right car. If you like the HPDE hobby you're silly to get the base car.

I just watched it as well. That top looks slick and being a hard top is a big plus in both looks and comfort ( noise). The problem is you can't see that awesome engine through the back glass on the Vert which to me is one of the great features of the new C8. I also found the Road and Track performance car of the year article interesting where they said the manual on the C7 was far more engaging to drive and quicker feeling that the new dual clutch on the C8. They kind of buried it. Although it's hard to take them seriously as they gave the award to the Hyundai. Pass the crack pipe.

plus the press cars are probably governed to dial back engine power 20% since they are not broken in yet. A point Jay mentioned more than once while blaming it on the EV VIN. ha.

For me it would be casual track days - I used to race in the CMC series but those days are behind me - haven't even been to the track in 5 years. It would be fun to take a car like that to the track, but it would not be a several weekend a year hobby for me. If I do get back into that would either get a dedicated car or use my 71 Camaro pro-touring car since it's already a pretty hard-core build and set-up to survive track day abuse.

I agree.
The C8 ZO6 is a better choice than the base car for HPDE.

The Non-Z51 suspension is still the better choice for a daily driver, as per the C8 engineers.

Both z51 and standard cars are drag limited. The theoretical top speed in both cars is well over 200 mph. That being said, the standard car would have a lower top speed with the z51 spoiler only. that means, theoretically, that the z51 car should break 194 without the z51 spoiler since the gearing is lower.

When I preordered my non-Z51 in 2014, it was forever known as the 'base' car on this forum and any used car website. Z-51 was seen as a completely different model, and was much more desirable, and quickly went on supply constraint followed by a price increase. Everyone knew that Z-51s had drilled discs, so they were easily to distinguish from base cars even when people bought the larger z wheels and z spoilers. The brake calipers do that for C8.

My 2017 was a Z-51.

A second set of wheels and track tires will fix that for a lot less than the cost of Z51, I suspect.

Jay didn't know what he was talking about. Tadge clearly said the car dialed back performance for the first 500 miles, not because it was a prototype. Tadge was just too polite to correct Jay. No way GM gave the magazines a car with crippled performance fo them to test and report on.

I am leaning towards deleting my spoiler, so I went z51.
What makes you think it will beat the base car's top speed? the extra 2HP?
