This was in a bag in the car, looks like ducting of some sort.

Removing Crossed Flagged Badge

gregbC8 — Fri, 22 May 2026 23:08:57 GMT

Does anyone know if the front cross flag badge on the hood has alignment pins on a 2023 C8 or is it just self adhesive? In other words if I remove it, will there be alignment pin holes?

Thanks!

New order updates

maxblack — Fri, 22 May 2026 23:00:02 GMT

Does any one else experience lack of communication regarding the status of a new order?

Little communication from the dealer. Been two months. Chevy is just a useless bot.

I can track anything across the globe, yet they can't send you status? They literally track everything throughout the build.

Body work

Ctevans — Fri, 22 May 2026 22:13:03 GMT

Turned too far left out of parking lot space and scraped front quarter panel on curb. Stupid I know. Would most of you use the body shop at the Dealership or go to a private shop for repair? I don�t know if it needs a full new quarter panel or not

Continue to have issues where PDR randomly stops recording

CitznFish — Fri, 22 May 2026 21:00:38 GMT

I've been through several SD cards, including Sandisk Extreme Plus 190Mb/s 128GB v30. The Dr will just stop recording whenever it feels like it. Is there any permanent solution to this yet?

Mine is set to record as a dashcam.
Set to overwrite old files.

I went on a drive today and stopped three times.
First segment recorded the entire drive
Second segment recorded the first 60% of the drive
3rd segment recorded the entire drive

I really wanted that whole 2nd segment recorded. I am so *expletive* tired of this PDR failing all the time. There has to be a solid solution by now.

Insurance

dsnorth2 — Fri, 22 May 2026 19:26:37 GMT

Thinking about changing my car insurance to the one that the museum offers. Please advise pros and cons about the insurance. They quoted me half of what I am paying now. Thanks for the info.

Finally finished my exterior mods! (I think!)

Bought my 1st NEW Vette last year, from MacMulkin, 25 Z51 coupe. I had a vision of what I wanted it to eventually look like, called it "Classy/Performance". 2LT, loaded, 2 tone interior, front lift, mag ride, etc. etc.
Had my ACS front splitter b/4 delivery, added clear top with custom painted body color sides, side windows tinted 25% ceramic, ACS side skirts, ACS license plate frame, OEM high wing, custom designed Forgeline 3 piece wheels from CWFL, Gerry recommended adding 1/2" to the front wheels to 19x9 and custom offsets, he was right!, full front PPF, body graphene coated, OEM jake hood decal, Carbon flash splash guards, some engine dress up but more to come, friggin mod bug.....Leaving power train alone till 3 yr warranty is up. Most of us do something to make it our own, I'm pretty happy the way it's turned out. Had a 19 GS, great car but the deals were too good last year and Costco's 3K coupon put me over the edge. Loved my 03 50th Anniversary Edition, AE Red with shale interior, had that 13 yrs, still miss that C5...
Of course NOW they come out with the C8 GS but still happy w/the Z51. It's a keeper for the foreseeable future...
PS, the outer rim on the wheels appears bluish in some pics, actually dark pearl black/gray but changes in the light and reflects the blue from the sky...centers are smoke, barrels black.

Warranty repairs with an associate TAC case/C8 woes/pls help

RIPC8 — Fri, 22 May 2026 18:09:30 GMT

I used to be active here 15-20 years ago (StealthZ06). I'm back because my 2023 C8 has been grounded at a local DFW dealership for two weeks with a coolant loss/overheating issue, and the service department is feeding me a narrative that goes against what I know of this car.

Breakdown & Diagnostics:
Cruising at 70 mph, got a sudden "Engine Overheating Idle Engine" warning on the HUD. Looked down and it was at 261 degrees.
Coolant is actively pooling in the engine valley (the "V").
The service manager performed some testing:

Coolant pressure testing - a drop in overnight pressure was observed each time they hooked it up, however they cannot find where the coolant is going (no apparent leaks, or sources)
Compression and leakdown - I was told these came back okay, but he didn't share any info beyond this
Borescope - camera showed that two cylinders are "cleaner than expected." I'm no mechanic, but from what I know in engine diagnostics, a "cleaner than expected" piston head is the textbook definition of steam-cleaning from a coolant leak. They also observed some pooling in the valley between cylinders 4&5, but not as much as expected.

Dealer�s Story:
Despite the steam-cleaned cylinders, the service manager explicitly told me they are "looking at a porosity leak on the intake manifold itself, not the engine."

My thoughts/sanity check:
The LT2 intake manifold is 100% molded composite plastic. Plastic cannot have aluminum "casting porosity."
The LT2 manifold is completely dry. Zero coolant routes through it; it only processes air.

If coolant is pooling in the valley and washing out two combustion chambers, it physically has to be a casting defect in the aluminum cylinder heads or the engine block itself.

There is an active GM TAC case, but the shop sat on the car for a week before touching it, and GM Executive Care just quoted me a 4-business-day callback window. I'm convinced the dealer is just throwing out nonsense to buy time because they are overloaded and terrified of a full warranty engine swap.

My Questions:
Has anyone dealt with a confirmed casting porosity issue on the LT2 block or heads?
How heavily does corporate TAC override a local dealer's diagnosis once the raw telemetry and borescope photos are uploaded?

I�m hoping GM Engineering audits the TAC file next week and rejects this "plastic manifold" patch-job. Any advice on pushing this through corporate would be appreciated.

Why Did They Let Them Do It?

Adaviss — Fri, 22 May 2026 18:00:24 GMT

I think the new LS6 engine is a very rare automotive event. Historic in fact! I plan to take full advantage, waiting for my build date for a 27 Stingray. Take the 13 to 1 compression ratio. Its a standard hot rod move. Everyone knows the benefits. Everyone has known forever that you need more than pump gas to use it. The Corvette team said we want to use it so lets work on the octane problem and find a way for pump gas to work. And they did! Why did the bean counters let them do it? It cost money to find the answer and will cost money in production on going. They could have told them to make due with a lower number. I think the $billion problem that is the 6.2 engine is paved the way to produce the best product they could despite the cost.

over fill oil

shaggyvette — Fri, 22 May 2026 17:35:04 GMT

Good afternoon, just had my oil changed on my 2020 Stingray. Got home and noticed that they put 10 quarts of oil in it. Car calls for 8 unless it's tracked. I don't track the car. Do I have a problem?
Thanks!
Dave

Keep watching The car appears to have the Z06 blade photoshopped out for some reason you can see the blur if you look close.

seat covers?

rawbar — Fri, 22 May 2026 13:04:35 GMT

I'm looking at buying a replacement for my stingray. Found a perfect one EXCEPT the previous owner paid the $$ override to get red seat bolsters. I'm not digging them. Are there any VERY NICE seat covers that will hide these but still look somewhat factory and dont move around? I'm guessing having these recovered in black will cost a small fortune.

All you have to do it send them to us and we take care of the rest, and return shipping is included.

C5-C8 Ultralow Seat Mount

This is the lowest, strongest, safest billet seat mount available for the Corvette. It will put your seat on the floor if needed. Using this mount with the Sparco QRT-R seat I gained almost 2 inches of head room over MTI rails with a Sparco EVO. Our integrated sub belt takes the guess work out of installing your 5 or 6 point harness. Not only that but it will survive an 85G mostly-rear impact. This seat mount saved my life and it can save yours too - just hope you never need to find out!

Follow this link to get yourself low.

C7/C8 Titan Tow Hooks

Made from 7075-aluminum and hardened 17-4PH stainless steel, this US-made aerospace-grade tow hook could actually tow a space shuttle. So it'll look bitchin' on your street car or pull you out of a tire wall easy peasy.

Prepare for launch here

C5-C8 Adjustable Camber Kit

The product the launched our company is available for all C5-C8 Corvettes. If your car sees any serious track time than a camber kit is virtually required equipment. Set your alignment once and never worry about it again. Everything is USA made and guaranteed for life.

Differential Mounts - C5 and C6

Mitigate wheel hop and stop your trans from flopping around during hard cornering with our offerings for the C5 and C6 Corvettes. Rather than knocking off the same product that everyone else has for the last 15 years, we came up with fresh and updated designs to address short comings from competitors. These billet pieces firm everything up without a huge increase in NVH and they are guaranteed for life.

For the C5 check this out and for the C6 check that out.

X-Wife Drop Spindles for C5 and C6

Combine GSpeed design with AMT Motorsport manufacturing and what do you get? The best God-damned drop spindle on the planet that's what! Machined on our 5 Axis CNC, they start out as 70 lbs blocks and wind up as the 6.5 lbs beauties you see before you. Available in plain finish or your choice of anodized colors.

Learn more about the X-Wife by clicking here.

C4-C7 Wheel Spacers

We offer 4 different sizes of wheel spacers. Our 1/4" spacer uses the lip of the stock hub for centering and can be used with stock length studs. Our 3/8" spacer pushes the wheel out a smidge further but the ring on the hub is no longer effective. We recommend going to the 2.5" ARP studs if you're using a 3/8" spacer. We also offer 3/4" and 1" spacers with a machined lip for centering. These spacers should use the 3.25" ARP studs.

For 1/4" and 3/8" spacer head this way. For 3/4" and 1" go that way.

C5/C6 Vulcan Motor Mounts

These mounts are now on their third variation and better than ever. A single bolt keeps your motor from moving fore and aft, while vulcanized rubber dampens the vibrations so they're not as harsh as solid mounts. We now use a hard anodized 6061 center section to keep the 2 rubber pucks in each assembly where they belong. Make no mistake these mounts do not feel like the pillowy soft oil-filled gushiness of the stock mounts. You are definitely going to feel more of the engine with these mounts, but your 350 lbs lump of a motor will not be moving all over your engine bay either when performance driving.

Follow this link to order yourself up a set of motor mounts

C5-C6 Extended Gas Pedal

Our product makes heal/toeing your C5 and C6 Corvette a breeze. It's a cheap and effective mod to increasing your driving enjoyment and I guarantee you'll love it or I'll give you your money back.

C7 M80 Adjustable Toe Links

After selling a different product for a number of years, we've decided to start making our own version of adjustable toe links for all C7 Corvettes. The previous product had fitment issues with various parts and quality issues with the heim joints. Trying to work with the supplier to correct the issues wasn't getting anywhere, so in order to best serve our customer base, we came up with the AMT Motorsport M-80 Toe Links which use 7075 aluminum, 17-4 PH pins, and FK Heim Joints for the strongest and longest lasting toe links on the market.

Head here to snag a pair.

Thanks as always for the support!

Transmission question

loonlodge — Fri, 22 May 2026 07:51:18 GMT

I have a 22 C8 with about 8000 miles. All the trans maintenance has been done at the appropriate time or milage intervals (fluid change and filter replacement). However I seem to notice when idling out of my garage, as I ease out then give it a little gas, it seems to rev a little before it fully grabs. Kind of like my childhood go-kart with a centrifugal clutch. I do not recall feeling this sensation previously, it seems new or more pronounced if not noticed before. It seems to function fine while driving and all else seems fine. Is this normal?

What happened to the binnacle animation?

Bellerophon — Fri, 22 May 2026 04:06:21 GMT

I recently traded my '23 Stingray for a '26. I love the new dash and interior, but one of my favorite features is gone! It was always exciting to see the see through Corvette in the binnacle when you entered the car. I like seeing the Corvette name on the screen, but can't the engineers give us something better? This calls for an OTA update. Maybe we'll all be surprised someday when we get in our Stingray and see a new animation.
