Z06 vs ZR1 Weight Discrepancy

I just rolled over to the SCCA race paddock and had my car weighed. 2019 ZR1 3ZR M7 stock wheels and tires, AP Racing brakes, full tank of fuel: 3647 lbs.
For comparison, my 2015 C7 Z06 3LZ M7 with stock wheels and tires, AP Racing brakes, full tank of fuel weighed 3559 lbs.
So the net weight gain is 88 lbs from Z06 to ZR1.

That's hefty for sure. Geesh.
Still don't see any stock cars in owners hands with tires only doing 1:14's at Summit or 1:57 at VIR though. Especially first or second time in the car.

In more detail, what are the ZR1/Z06 differences?
1) Different, internally larger but possibly not heavier supercharger?
2) Loss of cylinder deactivation.
3) ZTK weight vs. Z06 aero.
4) Enlarged exhaust tubing, and additional track day underbody aero plates.
5) Slightly wider front wheels, but wheels could have different weight +/- all around.
6) Front bodywork and fenders, rear valence. Also rear fenders?
7) Several additional heat exchangers and related plumbing.

This should be stickied somewhere.

I just had the car weighed again this morning. Same configuration, full fuel load, but with the 18" wheels and Pirelli slicks: 3592 lbs.
So the run flats and stock wheels are a 55 lb weight penalty over what most of us are running at the track.

When I went from 30 lbs wheels to 19.5 lbs wheels, I felt the difference immediately.
I’m sure if someone did change out the seats, removed the floor liners and carpets, you could save another 50-60 lbs and get close to 3500 lbs.
This is why GM should make a hardcore version next time. They can accomplish this very easily by simply removing stuff and selling the car with lighter wheels and tires. This doesnt require some massive RD like many claim here.

- There are several things, as a first time Vette buyer, that I found surprisingly absent from GM's options that companies like BMW and Porche offer. One would be the option of paying more for fewer options on the car. Another is paying 10x the regular "premium" paint upcharge to be able to select your own color - or individual interior colors for that matter. There is a huge ROI on factory customizing. I would presume it is more easily integrated with lower production facilities...but ZR1 production is less than 400/mo and the engines are hand built by 1 guy, so no excuses on there. And instead of asking $10k or more for an even more special engine tune that adds 20hp GM throws in the cat-delete high octane tune for free. Go figure. At least they had the good sense to charge a fair penny for the better intake.

Thats actually a substantial difference. Its rotational weight and that much weight off will make a huge difference in performance.

2) Hardcore versions don't sell, especially to an older demographic that wants amenities and softer seats.
3) The car is supercharged, how many are lining up to buy a hardcore supercharged Corvette?
4) Everything costs money. It has to be tested, seats crash tested/approved etc. The more options, the more testing, the more money spent. GM spent plenty money just to offer convertible and manual options and all those combinations.. Every additional change costs more money.
5) No one cares about your mustang.
It's clear not much thought goes into your posting.

LOL so what? It pulls like a freight train and will out run anything on the freeway. A couple hundred pounds is nothing in exchange for all the comfort and technology this car has that the low weight cars lack. I’d still buy it if it was heavier!
Now put your mustang on the scale and let’s all talk about how heavy and under powered it is!

We're done here....too many pissing matches to clean up. And frankly, it's a waste of time.
