I have one of these that I bought 3 months ago.

H6-40-RS

Its been great so far, no issues. I had a lithium battery in my Hellcat prior to my ZL1 for over 2 years without any issues. OEM battery was about 45lbs if I recall, the Anti-Gravity H6-40-RS is about 15lbs.

one special note, if you are under warranty, and end up buying one of these or any lithium battery, keep your factory battery for when your starter takes a shit due to heat.. you will know when it starts to slow down little by little.. when my starter began to slow down I knew it wasn't my lithium battery because the lithium has a voltage display plus it was beginning to slow down while the factory battery was still in.. The dealer will want you to have the factory battery in before they test the starter.. so I put the factory battery back in, it barely started, and off to the dealership it went.. they diagnosed it as a failed starter.. this is a known issue on our Camaros. so my starter is getting replaced as we speak at about 19k miles... as soon it comes out of service, the lithium battery is going back in! it is sitting in my office waiting for the car to come back

the battery is available at $500 shipped.. another member did purchase one and it seems to be working well for him too

Anymore feedback since its been a year?

The ZLE spec wheels came in at approx 22-23 lbs.. nice, light, not horribly expensive and gorgeous! They just take a while to make.. I believe stock 20" ZL1 wheels I weighed at about 28 - 29 lbs.. pretty significant weight drop!

So, you're saying lightweight wheels can save 25#?

The stock 20" wheels are 31lbs each on the ZL1. Most forged 20" wheels are going to be in the 24-25lb range and if you go do a 19" wheel, you can probably get that number down to 22-23lbs per wheel. If you want to fork out huge money for forged wheels, there are some lighter examples out there, probably closer to 20lbs each and there are some magnesium forged wheels out there too which are super light.

I have 19" Signature SV502s and they are 9-10 lbs lighter per wheel than OEM ZL1 wheels. They're not cheap but they're very light and just as strong if not stronger than OEM wheels. Plenty of lightweight forged and flowform wheel options on the market for these cars.

Checked out the 502s, very nice https://www.signaturewheel.com/product-page/sv502. Is your offset the same as stock?

$1125/wheel versus, what, $900 stock (from a dealer)? Not bad at all.

I had an exedy dual clutch lightweight flywheel in my previous lightweight sportscar..... I loved it. I'd get to 7450 RPM's quicker. It was a noticeable difference. And yes it took me about a month to learn the sweet spot of the clutch. It was either kill or chirp for about a month, especially the first 2 weeks (3 kills a day maybe). Once I learned it though, I Loved it, and it definitely kept the integrity of the system, no slipping during a hardcore powershifts into 2nd or 3rd at 7450.

For example, what do the stock wheels weigh vs the Forgelines?

My investigation indicates that aftermarket front wheel are around 3 pounds lighter and rear wheels are 4 or 5 pounds lighter so in total we're talking maybe 16 to 18 of unsprung weight for my 2020

There are some HRE, Forgeline, Vossen wheels, probably some others that weight 6-7lbs lighter per wheel, they just cost a LOT.
