Sooo I've been geeking out on the technical specs too and I'm pretty sure we're gonna see solid aftermarket support soon. NGL, the glass roof is a bit nerve-wracking, but I'm satisfied that Rivian builds those mounting points into the frame. For your situation, I've found that third-party T-slot setups work well for balancing cost and utility.

Thule WingBar Edge vs Rhino-Rack Vortex StealthBar

The Thule bars are highkey the best for staying quiet. Honestly, no complaints about wind noise even at 80mph. But they're pricey! The Rhino-Rack Vortex StealthBar fits that rugged R3X rally aesthetic better cuz it sits lower to the roofline. Plus, it's usually way more budget-friendly.

Pros for Thule: Literally silent, premium finish.
Cons: Expensive.

Pros for Rhino-Rack: Low profile, fits the rally vibe, cheaper.
Cons: Might be harder to mount some bulky boxes.

Best choice? I'm happy with Rhino-Rack for a rugged look. Just double-check the dynamic load rating before you toss a tent up there! gl!

So, before you bolt anything onto that R3X, you gotta understand how these integrated systems actually distribute stress. On vehicles with glass canopies, the mounting points are basically the only thing keeping the roof from cracking under a heavy load. Unfortunately, I've had issues with universal clamps on other EVs where the vibration caused micro-fractures... super stressful tbh. For the R3X, I'd highkey suggest waiting for the Thule WingBar Edge with Flush Rail Kit if they release a specific fitment. It's way lower profile which helps the efficiency you're worried about. If you're dead set on a tent, honestly, you might wanna look at a hitch-mounted rack instead to be safe. But if you go roof-side, the Yakima Landing Pad 22 with SkyLine towers is probably gonna be the most solid interface. Just be reallyyy careful with the torque specs... seen too many glass roofs ruined by over-tightening!

Honestlyy, Rivian OEM bars are gonna be pricey. I would suggest Yakima JetStream Black Crossbars since they use T-slots and stay quiet. But be careful with that glass roof... honestly, I mean, make sure to check the dynamic load specs before u toss a tent up there!! For a budget-friendly pick, Thule WingBar Evo 135 is usually way cheaper on sale. Just gotta watch that roofline tbh. gl!

Story time: I actually went through this exact stress last year with my other glass-roof EV. Honestly, I found that cheap universal clamps are a massive safety risk on those sleek designs.

Quick tips:
* Stick to the frame-integrated mounts to protect that glass.
* I've had great results with the Thule WingBar Edge Roof Rack System for staying quiet.

Safety first, seriously... you dont want a shattered roof mid-trip! 👍

@Reply #5 - good point! I totally get the DIY jitters, especially with that gorgeous glass. I remember installing my first rack on my old car and almost scratching the trim within five minutes... talk about a heart attack! We have a solid consensus that the integrated mounts are the only way to go to avoid cracking that roof, and the big brands are definitely the safest bet. If you want to keep the rally look but want more flexibility than the OEM stuff, here is what I am looking at:

• Yakima SkyLine Towers used with Landing Pads. These are amazing because you can snap the whole rack off in seconds when you arent hauling, which helps a ton with highway efficiency!
• Thule ProRide XT for your bikes. I love it because you dont have to take the front wheel off, which is a lifesaver when you are tired after a long trail ride.
• Yakima SkyBox 16 Carbonite for the extra gear. It has a dimpled texture that actually helps with drag, and it looks rugged as heck on the R3X... totally fits that rally aesthetic. Doing it yourself is totally doable if you just grab a decent torque wrench and take your time. Just dont rush the setup and it will be fine. Super excited to see everyone's builds once these ship!

So I’m curious, do you have experience installing these systems yourself or are you looking for a professional shop to handle it? I’m a total DIYer but honestly, the R3X has me a bit nervous because it’s so new. I’ve been reading up on it and here are a few things I’m worried about for us home-mechanic types: * Missing torque specs—if we over-tighten anything near that glass, it’s game over.
* Scratches on the finish because the mounting points look realy tight to the body in the photos.
* The height of the car might make it awkward to reach the center without a proper platform or ladder. Basically, I’m worried we might need special tools that Rivian hasn't even released yet. Like, what happens if the mounting bolts are some wierd proprietary shape? Definitly something to think about before you buy a bunch of parts! I'd hate for a simple DIY project to turn into an expensive insurance claim lol.
