Ugh…an unfortunate update. I had a passenger in my backseat for the first time in a while and he noticed something that made me 🥲

Not sure what happened but I’ll be reaching out to @HGP_AutoGlass about their warranty process soon. At least I have plenty of pictures to prove it was fine for several weeks before this random crack appeared out of nowhere!

Here’s hoping the process isn’t too bad but I’m really not looking forward to having to coordinate the tint/install sessions all over again and footing that bill…ugh.

Bummer! I remember how stoked you were to get those. Maybe if you butter Hyperformance up when you talk to them they'll at least cover the installation cost. Tell them they probably sold (or will sell) some more based on your excellent review.

Product review for Hyperformance louvered glass windows!

I knew the moment I saw these and before I’d even ordered my car that these would be my very first mod. I’ve always loved the classic look of louvered windows but I’m (personally) not a huge fan of the black plastic version that you just stick on with 3M tape — and how I’d go about cleaning under them was a mystery lol

So when I saw these last year I knew I had to save up and hopefully catch a Black Friday sale — and I did!

The only challenging part I encountered was having these professionally tinted. I had to go to two different people (one for tint, one for install) for this which wasn’t a big deal and, looking back, would honestly be my preference in order to take advantage of the expertise of both.

Here’s a collection of photos of the finished product (including a shot from the interior for anyone curious):

I have some recommendations and tips for anyone that is considering purchasing these:

• the company (Hyperformance Glass Products) posts discount codes a few times a year that take a considerable amount off the cost ($200+ during Black Friday) so I recommend checking posts by @HGP_AutoGlass AND their Facebook page during sale season!
• pay attention to the company’s fine print after ordering that states when your shipment arrives, you check the windows BEFORE you accept the delivery. If they are cracked or damaged, you are supposed to refuse delivery and contact Hyperformance. My FedEx person just left my box outside (no signature required) but thankfully, my windows were undamaged so no issues
• if you’re interested in tinting these, do so BEFORE they are installed (make sure you know the tinting percentages of your other windows so they match!). Some shops won’t even work with these if they’re already installed in the car, as it’s more difficult to cut and apply the custom shapes that will be needed.
• wait to gather tinting quotes until you have these in-hand and can physically take them to local tinting shops. I recommend finding people that specifically work with cutting custom tint (for cars, businesses, etc.), as these were definitely a custom cut for my guy and required him to create paper templates and hand-cut the film with a knife. Not a complex process according to him, but the first few shops I spoke with weren’t willing to do this and only worked with precut tint.
• Your tinter will likely NOT believe you when you tell them these are glass. They may do a “tap test” with their finger and still won’t be convinced, but rest assured, the tinting film WILL adhere (I guess it doesn’t stick to plastic?). My guy did a small knife check on a back corner and even looked them up on Hyperformance’s site because he was still paranoid lol
• while the packaged windows themselves have stickers on the protective wrap that warn the tinter, I’d recommended reiterating they should NOT apply concentrated heat to these — just in case!
• have an auto glass installer do the install as they know exactly how to remove and preserve your OEM windows and properly install/seal these new windows. Assuming you want the OEM windows back, make sure you mention that so they don’t keep them to sell them or something.
• make sure you tell the glass installer NOT to press on the center of these windows to “push them into” position. Another forum member mentioned that their glass cracked from this scenario, so I mentioned it to my own installer (these windows do have pins and according to my guy, he said they never press on the center, but a less experienced person may try to).
• I’d also recommend you tell them to apply enough rust inhibitor during install, which was another helpful tip from @Evolvd!

My tinter charged $100 to custom tint the set and my installer charged $200 to do the install for both sides. He said it took his guy an hour or two to swap them out.

It’s funny, both shops that worked on tinting and installing these for me told me that they’ve seen hundreds of Mustangs come through but NEVER had they seen this mod before! It was an intimidating project for them initially but both were up for the challenge. I encouraged them to take photos and share on their socials if they wanted to showcase their diversity in what their people can do!

Overall, I absolutely LOVE the look and feel of these windows. They add that classic muscle car look without sacrificing quality, class, or ease of cleaning/maintenance. The extra louvered window lines just make her stand out even more so I’m very happy to have a more unique addition to my car. Sure, maybe upon first glance, the average person wouldn’t notice them at all because it’s such a subtle mod — but I do and that’s all that matters to me in the end!

Glad to see Hyperformance is getting the creds and you posted a thorough review of the product!

I've been posting about them since they debuted at SEMA back in 2020/2021? Here's an older thread of a few I've posted about in here:

They look absolutely great on your S550!

Any updates as to the crack?

Might not be too bad. Maybe someone can replace just that pane. And tint the replacement beforehand.

Recently discovered I have a similar crack (cracks) that showed up on my passenger side. Very very thin, and you can barely see them in some lighting, but you can catch a fingernail on them.

Sucks because I don't think it ever got bumped or anything and it was fine for a long time. I didn't even notice, a friend of mine pointed them out to me.

Let me know what happens with the warranty. My drivers side is still good.

Dandee, any new developments re: that nasty crack?

@DandeeLioness and @NightmareMoon

Any updates? Did Hyperformance Glass replace the 1/4 glass - and/or cover the R&R too?

Both of you had similar failures.

 

[NightmareMoon]

I have not reached out to them. To much going on.

 

[DandeeLioness]

Hey all — I do have an update on this issue and finally some time to post it! Gonna tag a few folks who inquired so they get the notification: @Farkel @Cobra Jet @NightmareMoon

I reached out to Hyperformance a few weeks ago using their warranty form and got a response about a week later. They agreed that I was eligible to be sent a replacement for the driver’s side window after their team reviewed my photos and the details I’d included about the crack.

Overall, the experience was painless and I was very happy to receive the replacement on time and as promised!

For right now, I’m just going to hang on to it and see if the crack gets worse, splinters into more cracks, etc. You can’t see it from the outside if you’re not looking for it and I’m not willing to go through the expense and process of having the new window tinted and installed right now. But at least I have it on-hand for if that becomes necessary down the line.

I’m really hoping it doesn’t get worse and I do still love the look of this mod very much! It’s rare anyone rides in my backseat so I’m not super worried about it right now from a cosmetic perspective. It’s unfortunate that the crack happened at all but they did right by me. I’ll update here again if any other developments happen down the road (pun intended )!

I wonder if the small panes are expanding/shrinking more than the surround around each panel. idk

 

[22MAVXLT]

I didn't even know these were out. They look great! But DAMN, $100 to tint these? There is no way we could get away with those prices in our shop. Hell, we get told all the time $100 for 2 front doors of a truck/suv is too high. But, I will gladly tint these all day every day for $100 a pop.

 

[Evolvd]

I paid $75 each to have both of mine tinted.

That's great to hear that Hyperformance reviewed and sent you another 1/4 under warranty replacement.
