'19 ZR1 all good except that wheel gap /Dallas auto show

The .2 does have the option for $2600, but the yellow one in the picture (991.1) did not. The GT.1 models, minus the GTS, did offer the lift. The non pasm sport management optioned 911 did have a wheel gap. Both cars in the picture are mine.

ZR1 will have ride compliance built in that the GT3RS won't though. I think this is a compromise made to give the ZR1 the potential for dual personality. Considering the grip and braking ability as well, these cars nose dive big under braking, so they'll use all the wheel gap in the front, and then some.
You could clearly put more spring rate into the car, drop the suspension ride height, etc, but with harshness added. Lowering the car you take away a lot of suspension stroke that it needs to remain planted in high lateral loads through high frequency surfaces like areas of Nurburgring.

In their 2015 Lightning Lap test of the Z06, Car and Driver noted that, "The tall wickerbill-equipped spoiler on the Z06’s tail increases rear tire loading with speed, driving the body closer to the ground. At 145 mph, the rear of the car is more than an inch lower than the Z06’s static height. The spike in the rear-height trace at the end of the straight shows the car pitching forward, the result of load transfer during braking."
Emphasis where added is mine. Note how the last sentence exactly matches what you pointed out would be a factor. Check the link above for the ride height traces.
Now imagine the upcoming ZR1 which has 60% more downforce that the Z06.
Like you said, can go with stiffer springs if one really wants that look but pretty much everyone is going to really hate the resultant ride on the street.

Well gents, the reality is that 99% of the folks that buy this car will never take it to the track. But just like my C5 Z06 the engineers have to design to the lowest common demoninator, i.e the guys who dont drive it to the track vs guys like me. So they have to have an acceptable amount of ride and compliance but yet be able to perform when it gets to the track. It is a production car after all..

Not sure why the American manufactures continue to have a 'wheel gap challenge'... BMW, Mercedes, Porsche all do significantly better in tucking the wheels up inside the fenders.
Wouldn't be a deal killer for me... but they do look 'high' when standing still.

The gap on my C4 ZR-1 has always annoyed me. I assume they needed to have it for wheel travel, but as mentioned, other cars have minimized it. I think the rear wheel gap on the BMW 1M is perfect. They do not need to lower the car, maybe just extend the fender down closer to the wheels.<br/><br/>Anyways, it is was it is, and as they say at the Bank street station in London ....

The wheel gap is due to the design of the suspension, and mostly being the leaf Spring. I remember reading somewhere that the flex needed for the leaf Spring is greater then a coilover setup which almost every other car has. If you ever notice the corvette only suffers this, the camaro, and CT’s-v don’t. In fact the camaro almost comes perfect just about everyone Iv seen. I always pay attention to the cars wheel gaps and it amazes me how Porsche gets there tire to tuck, there really isn’t anymore room inside the fender then we have on our cars yet I couldn’t fit a finger between the fender and tire, but then Again I love my Z06 and bought LG spindles and problem solved

Not sure why it matters. The car will run like the hammers of hell and I suspect anybody that messes around reducing the wheel gap will F the car up from a handling standpoint. The Z06 gets the best handling at the stock ride height. Whenever I see a lowered C7 I suspect compromised car.

^^^and other than suspension pickup points and the frame it has almost nothing in common with the actual C7 road car suspension. That car has coilovers, I would expect a *very* hash ride, and doesn't have to deal with the irregularities of the road.
Personally, I am amazed that GM has build a road car with a decent ride, can get down my gravel road, and destroy anything on the track. If you're in it for cars and coffee they give you a way to lower it but realize it won't be as good a ride or handling.

I'd like to see the C7.R do this

C7R is set up for TRACK USE, C7Z Street and track.

Anyway, I lowered mine an inch recently and had the MRC updated and can't say the ride was affected negatively...quite the opposite.

The wheel gap is probably needed for these show cars considering they are loaded and unloaded into trailers, etc. That's why they come higher from the factory to accommodate the transfer trailers. Most dealers could lower the cars, but just leave them as is and pass the responsibility over to the owners.
I know the Z07 suspension on the Z06 does not lower on stock bolts as far as the non-Z07 suspension does and that's where the drop spindles come in if that's the look your going for.

In looks department, this car looks stupider by the day. Thanks god nothing over ZR1.
Corvette has always been elegant. But ZR1 looks like a Cormaro + Shelby + Some Other Freakshow, all glued together rather hastily.
It is a beast. In its literal sense, as in "Beauty and the Beast".
We used to think how brutal and beautiful Stingray looked next to a Huracan. But this one... Eyykk.

so so far the worst I have damaged my carbon front splitter is a slight scrape on the underside.
i have to literally ly on my back to see it
i can live with that.
My last c6z was lowered on stock bolts with the CFZ/z07 package.
i did more damage to that splitter than
my 16/z06/z07 on LG drop spindles
