How much do the PP1 brakes weigh compared to the PBR brakes on a new edge?

Gittin Jr said it felt like 3500lbs, although it's much heavier - so I guess that's a good thing considering he's used to a car that weighs 3200lbs and has more power than the 500.

Great interview. Billy's comments on the gearbox - as well as hearing it shift at Goodwood - appears to give it the edge over it's competitors.

Also loving the look of it. The sound, though, that's much nicer than the muted farts you hear from turbo'ed V8s.

Like what?

All cars are gaining weight because we can't take responsibility for our actions and incompetence. So cars need to save us from our own stupidity with a lower and lower bar each year. Screw improving driver education and training, we need more & more heavy airbags, and heavier cars with higher crash standards.
I bought a 2004 Z06. I"m finding it to be a great daily driver. They are a LOT lighter than a C7. And I don't feel like I'm driving a video game. I agree on the safety stuff and the options that "everyone" wants. Maybe I'm one of the few that doesn't feel that way. I missed the heated and cooled seats, the touchscreen, nav, etc. at first, but as I get used to the car I'm really enjoying the feeling of balance and grip along with a more compliant suspension that goes with a lighter, lower chassis.

I have been surprised and amazed how much better a car feels on the road when it weighs closer to 3100 lbs instead of 3800 lbs. I really miss the Voodoo engine, but I love the Corvette chassis.

Agreed. The GT350 currently weighs 3810 or something like that after 2017.
Let's for discussion say that's correct, so that leaves 190 lbs to cross the 4000 lbs mark. Supercharger, coolers, larger brakes and the DCT, I'm thinking that's at least 200 lbs. That's not factoring in the larger wheels/tires (which may be lighter/offset by the CFTP flavors).

I think it's going to __really__ close with the CFTP, between 4000 and 4100, and the base will weigh another 100-110 lbs (4x CF wheel difference, rear seat delete). Are the hood or fenders any lighter? vs. a GT350?

Sweet video.

I still laugh when people complain about how much the GT500 weighs, or how a 2018 Mustang GT weighs 3,800lbs. Corvettes are not lightweights:

C7 ZR1 - 3,680lbs

C7 Z06/Z07 - 3,524lbs

2LZ M7 Z07 Coupe - 3,546lbs:

C7 Z06 - A8 with just a tick over half a tank is 3,510lbs with no driver:

2016 C7 Z06/Z07, manual transmission, 3/4 tank fuel - 3,506lbs.

There's no way a supercharged 3,800lb S550 chassis is going to weigh as little as a 3,680lbs ZR1. A supercharger is at least 100-150lbs added on to a 3,650lb radio-less GT350R, add a radio, heavier brakes, heavier wheels, heavier wing, bigger coolers, heavier tranny, and I doubt it will be under 4,000lbs. Even more for the base car. Even if the car had carbon fiber wheels, hood, fenders, doors and trunk, it would not be anywhere near as light as a C7 ZR1. I don't know how you could think otherwise.
Thus why if I ever buy a vette, it'll be a C5Z or C6Z. Those cars were light.

The answer is always BUY AN OLD CAR that does not need to meet current safety standards.

But they are slow compared to a C7 or GT350, even though they are lighter.

The C6Z may be my favorite "modern" Vette (where I guess that's C5 and up ...). I think it's better looking than any C7, it has the right mix of classic Vette design elements, functional ducts and a nice wide stance - while remaining consistent across the design and not having a bunch of design cruft. Plus, since the C5, the LS7 is the most glorious engine put into a Vette.

The great thing about the LS7: it's a H/C (and supporting mods) away from ~650HP naturally aspirated.

I fully recognize the C7 is better in most metrics (certainly variants like the ZR1), interior quality/electronics, etc., but there's something pretty f***ing fantastic about a manual only 427ci Corvette model. :D

I've found that absolute speed doesn't always equal driver enjoyment. I'm pleasantly surprised with how much more real-world grip and acceleration comes along with a better weight balance and a lighter car. Yes the power to weight of the C5 Z06 isn't quite as good as the GT350, but the C5 is more likely to hook up the rear tires - having the transmission in the rear of the car.

And the power band is a little more accessible at normal speeds. On track the Z06 feels handicapped by the truck engine, but on the street it feels like the power is always there.

not to mention most of america wants options. Sure, a fox body weighed 2900lbs. But it didnt have heated/ac seats, irs, 460hp, nav, adaptive cruise and all the other options a new car has.
Nor an IRS.

eh. Not a fan. Probably comes from being 6' 4" and not slender. I also must have a V8. The sound is so much better than a 4.

That's one big thing about the GT500 I noticed. It sounds AWESOME! I think some other blown cars the supercharger whine is a little too overpowering, but in the Goodwood clips you can hear blower as well as engine. The combo of a high revving V8 sound with the blower whine is AMAZING.

Cam and tune away from being better P:W, and it'll be faster around a autocross or road course. And cheaper consumables. It's what I'd buy for a track only, but still streetable car, myself.
