> The panoramic roof on my Lexus RZ looks amazing, but it gets pretty toasty under the direct sun, even with the dimming feature.

Sooo I totally feel you on the "giant heater" thing lol. I'm a bit of a tech nerd when it comes to EV thermals, and honestly, even though that electrochromic glass is super cool for the wow factor, it doesn't actually block all the IR heat like a physical barrier does. I've been looking into some custom stuff because I'm worried about the dash materials warping too.

Before I give advice on the specific brands I've seen, can you clarify one thing: are you looking for the mesh style that lets some light in, or a full blackout shade? I mean, some people hate the mesh cuz it still feels warm, but others hate the "cave" feeling of the solid ones. Also, did you get the Lexus RZ Dynamic Sky option or the standard fixed glass? It kinda changes the fitment for some of the clips. Lmk and I can tell you what worked for my buddy's RZ!

Respectfully, I'd consider another option besides those super expensive OEM parts. I mean, the official Lexus stuff is nice, but $500+ for a mesh screen?? That's literally wild to me lol. I'm kinda new to the RZ life but I've been hunting for budget-friendly fixes cuz the heat is seriously NO JOKE.

I actually found some way cheaper alternatives on Amazon and eBay that do the exact same thing for like a fraction of the cost. Check these out:

* VViViD Perforated Black Adhesive Window Privacy Wrap Vinyl - This is a DIY project but super cheap if you're feeling brave!
* Nansun Custom Fit Sunshade for Lexus RZ450e Panoramic Roof - This one is usually under $100 and clips right in.
* NICEKE Panoramic Roof Sunshade Foldable Mesh for Lexus RZ - I saw this one recently and it looks basically identical to the pricey ones.

Honestly, I'd rather spend that extra cash on charging or a nice road trip! Just make sure to check the reviews for any sagging issues, but most of these clip-in ones are solid. gl!

Oh man, I totally get it. I basically had the same freakout when I first got my RZ! Even with that fancy dimming tech, it literally feels like a giant heater over your head during a summer road trip. For your situation, I would suggest looking into the Lexus RZ Panoramic Roof Sunshade Assembly. Honestly, I ended up getting a set from a random shop on eBay that were custom-fit for the RZ 450e, and they've been a lifesaver.

I was kinda worried about the clips scratching the interior trim, but they just snap right in and hold the mesh tight so it doesn't sag. It makes a HUGE difference in the cabin temp, like, seriously. Plus, you can just pop 'em out and toss them in the trunk when it gets cloudy. Kinda wish Lexus just included them, but yeah... definitely get the physical shades if ur worried about that UV wear. good luck!
