"GT3 Touring" Ducktail Spoiler

Hey folks! @circuit.heart here, had a bit of a process with Rennlist admins so I now have to post under a vendor account since the original thread for the ArtnD 996 Touring spoiler has been nuked, I would like to announce in this new thread that development is 99% done and preorders are open! https://artndvehiclestudio.com/produ...ouring-spoiler Video is worth a thousand photos: You Tube Since I posted this on social media the reception has been insane, so I and my print partner picked up another Bambu farm to handle demand! We are at the last steps of optimization - the prints' precision, strength, and ease of install have been great and we're just dialing in our bonding and annealing to make sure there's no long-term shrinkage or expansion. Once we're confident in outputting consistent high quality, we'll start shipping customer units. Some of the more frequent questions I've been receiving: Does it come color-matched: Nope, these will ship in primer unless your car is close enough to my showroom (Milpitas, CA) that you can bring it in person. Color-matching would be an additional cost. Does it fit Cabs: Yep Does it fit Carrera 4S: Yep, see below Install works exactly the same as the stock louvres besides suggesting you tuck the 4th brake wire under the motorized teatray for a cleaner look. I've tested multiple versions and prints of the design to hold up to >130mph (exact limits hard to reach as I don't have Autobahn access) and the extra stability is very felt! Timeline-wise, we've received many preorders so there's a backlog already while we're still doing final quality work, but I think we can start shipping the first ones about 1-2 months from now. Introductory pricing is $695 + shipping. Let me know if you have any questions!

Congratulations Brian! This is so amazing.

Looks nice! Very similar to the DNS Performance �mini ducktail��

(saw answer in later post) Does it still go up/down -C4S here. Another vendor here makes a LED kit that replaces all the back taillights, and it would look great (my opinion) if it had the 3rd brake light also. comments? YMMV

Looks great and very clean install, wish I hadn’t just installed the Rennline mini deck lid spoiler or I would definitely be a customer.

Love the Idea, just not a mesh fan

Yes, as a drop-in replacement for the stock louvres I'm not touching the teatray movement. It also still exposes the 4th brake light.

Very nice !

Quick update here as nothing's polished up enough for social media: Ed and I have been trying things nonstop since we got to the 99% milestone, now we're trying to get the last 0.1% and of course that's the hardest part. With enough heat I was finally able to get our "99%" print to warp, and it does so in an unfortunately ugly way: So I redesigned the underside of this section to have a stiffening rib, which doesn't eliminate the problem entirely but it at least makes the curvature of the thermal warp more controlled. We have also been fighting 1 or 2 of the joins between print sections "breathing" as they cure, which leads to, if you paint the part before it's done breathing, a very subtle crease in the final painted part. With tweaks to our bonding slurry recipe and curing process we got this down to just a very subtle line showing up for about 1" in the latest part, but that's still unacceptable IMO. Haven't taken a photo of this because I actually can't see it on the camera (good news?). What I think is happening is that this being a thin-shelled ASA print, there is internal tension between the layer lines and it's basically allowed to show up as we attack the ASA with both heat and thinners (in the paint). This has now led us down a rabbit hole of trying different filaments, drying recipes, and bonding methods to appease the printer gods. ASA-CF was first up to bat given we know ASA well and the carbon version of the filament supposedly had much lower thermal expansion/contraction. While true, it's also way more brittle than straight ASA and we snapped the black print in question trying to uninstall it from the test jig. We then tried PC-ABS which seems to consistently warp itself off the bed, so it feels like it has even more internal stress than ASA; and if we can't print it, of course it won't work. We're now trying straight polycarbonate which will make us revisit the bonding recipe (can't just acetone slurry it). JB Weld just because I wanted to see what happens: Turns out, over time JB Weld shrinks as well, so thank goodness we let one sit out forever otherwise we would've only found out through angry preorder customers. I am still considering using it though since if it shrinks, we could just let it cure for a long time before letting filler primer cover the miniscule gap. If there's any silver lining it's that all this printer operations has developed our raw prints to be the best quality they've ever been. It saves a lot of post-processing time not needing to sand these guys much at all. Just knock down some of the difficult edges/steps after bonding and go straight to primer. So that's where we are now - if you've preordered with us and are patiently waiting, we really appreciate that, and hopefully this gives some insight into what we've been doing the last few months. Long-term testing is super slow but when done thoroughly gives us confidence that our product will last as long as an OEM part does. Cheers!

Honestly, Id rather it be "10 minute Install, 20 years more RETRO". Ive been wanting one of those rear luggage racks that attach over the rear decklid for my 996 like on the old air-cooled cars. Im envisioning one that is mounted level to the ground, with the rear mount taller than the front mount, so its up and out of the way when the speed activated spoiler raises up. It will go well with my factory Porsche RTS roof rack. Can you design something like that? I would think it would be popular with the growing 911 rally/safari/overlanding crowd for just a bit more luggage space/options.
