Replace your wheels with 1 piece carbon fiber wheels from Carbon Revolution and you can get more performance in
acceleration/stopping/track times/quietness/less vibrations. This company makes the OEM carbon fiber wheels for Porsche 993
and Ford GT and Ford Shelby GT350.
lb for lb, these Carbon Revolution have more weight in the center of the wheel so there's less gyroscope
affect than another brand's wheels that weigh the same.

No, Carbon Revolution sells $12k/set but it could be less if GM cuts a deal.

Indeedy!!

Also, Carbon Revolution price of $12k/set is for the exposed carbon fiber weave. The Ford GT has exposed carbon fiber wheels whereas the the Ford Shelby 350GT is black paint over carbon fiber to save $. So between GM cutting a better deal and on a painted carbon fiber wheel, the price would be even less.

Yes It would have been nice. I personally like the Zo6 wheels better than the Zr1. But they are growing on me some.

lol, this is paid marketing. I could watch that guy driving and tell you he's not driving hard enough, or even close to, to notice the difference in weight. Even if you saved 10lbs per wheel, that's like 80lbs of "dead" weight by most calculations. There are much better bangs for your buck. If it made the car 0.2 sec faster around a track with a pro driver I'd be absolutely shocked.

Also, you'd notice more vibrations and harshness because it's lighter. Mass damper type thing.

With that said, GM should have definitely had a forged wheel standard on the C7- certainly the ZR1.

Did you watch the video links and read the links that I posted? 1.2 to 1.5 seconds if you just slap the CF wheels on. 2 seconds if you recalibrate the suspension for the CF wheels. I believe in the videos and reviews that I've seen that I've posted by well-known car magazine reviewers.

Because you doubt the professional automotive reviewers, I assume you also doubt facts such as global warming, low 3.8% unemployment rate, etc.

In 9/2018, Ferrari has just contracted with Carbon Revolution to make cf wheels, which allowed Carbon Revolution to hire 500 people to help increase production from 10,000 to 150,000 wheels (almost 40,000 cars). This economies of scale will have newer manufacturing processes and raw materials purchasing power to drive the cost down further. I would buy them when the price is down to $4k/set which is in line with other GM Corvette upgrade packages prices.

lol it’s paid marketing. If an extra $7k on track wheels made you 2 seconds faster, everyone would have them and they’d be operating at an economy of scale. 2 seconds is me vs a top pro driver. 2 seconds is 200hp. 2 seconds a good street tires to slicks. It’s not the equivalent of 80lbs out of the car.

For more performance, I'd rather do a CF wheel mod (someday) than an engine mod. Engine mods introduce overheating, unreliability, etc.
Keeping my 2017 Corvette Stingray naturally aspirated means easier to maintain, better reliability, and better throttle response.

In my 2017 Corvette Stingray, on public roads, the engine produces way more power than my 285 wide rear tires can grip the road which causes the tires to break traction easily when I accelerate fast. Therefore, before doing any more power mod, I'd rather get wider 295 wide tires to help get more traction. Even my friend's Grand Sport with 335 wide rear tires break traction easily during hard acceleration.

In my 2017 Corvette Stingray with stickshift, on public roads, the engine produces way more torque power than my 285 wide rear tires can grip the road which causes the tires to break traction easily when I accelerate fast. Therefore, before doing any more power mod, I'd rather get wider 295 wide tires to help get more traction. Even my friend's Grand Sport (with stickshift) with 335 wide rear tires break traction easily during hard acceleration (he says he hydroplanes going up freeway ramps).

village idiot

Yeah, I'd take weight reduction over power too, but weight reduction is generally very expensive, limited in availability and otherwise has less effect on performance per dollar spent. I'd rather drop 200lbs than gain 20hp, but it costs a tens of thousands to drop 200lbs (unless you're talking about gutting the car) and under $1000 to gain 20hp. Heck, I'd take a 200lb loss over 50hp gain any day of the week.

I don't think your friend knows what hydroplaning means. Either that or he should stop accelerating hard UP freeway ramps. No wheel is going to fix that.
Every car can always use more grip, but I don't really have any concerns overpowering the rear in my GS, even on stock PSS. On something like an NT01, you can pretty much floor it whenever and not worry about the rear breaking loose unless I'm trying to break the rear loose.

With that said, 295 on a stock wheel probably won't help noticeably. Just go to a stickier compound (Re71, NT01, etc) and/or get wider wheels so you can run a 315 rear.

No idea what this has to do with wheel weights though.
