"GT3 Touring"-Style Decklid
Hey folks,
I have been trying and failing to find a very specific decklid for my 996.2 NB - a GT3 style piece, but without the upper wing, just the lower ducktail. The closest thing I've come across so far is an RSR decklid, but 1) these are straight-up motorsport parts without factory hinge/latch provisions and 2) they're slotted for a chassis-mount wing, which I don't plan on doing to my car. Ignore the air scoop:
Does such a part exist? I'm not opposed to buying a 996.2 Aerokit decklid and hacking the wing off myself, it's just a waste of money if we don't have to do that. Alternatively, if it doesn't exist yet, would anyone be interested in me making a batch? Excuse my Photoshop skills, but I think it would look quite handsome:
But yes, if this already exists and I just failed to find it, I'd appreciate being pointed in the right direction!

Big update! Didn't upload any pics of the fill/smoothing process on the print (may be a trade secret, my bodywork partner has been figuring out how to efficiently process prints), but it's painted and fitted for real now and I'm very proud of the result.
I got to look at various specs of GT2/GT3 cars on Sunday and interestingly enough, all of them used some form of expanded diamond mesh. But... I wound up using hex anyways because it's the thinnest one I can buy given a certain hole size. Vertical space is at such a premium with this design, my decisions were made for me. You're right, it's gorgeous.
The panel gaps are tight after I wrapped the edge of the piece around the teatray. I have to refine this idea a little bit; while I love it, it's also tight enough that anyone with a misaligned teatray could run into issues.
I think the stock louvre panel isn't very aesthetic when popped up, so for me it stayed down as much as possible. This, however, I would pop up just because it looks like an intentional spoiler. I love this. The peek of the teatray slats, engine intake and fan intake is everything I wanted it to be.
Checking for flaws in harsh artificial lighting. The leading edge on this prototype is up by a fraction of a degree due to how the mesh sits down on the teatray - we're literally out of space. I think I can fix it easily with two shims - assuming I'm right, I'll bundle said shims and instructions with each spoiler.
Besides that minor issue all that's left is some QoL updates to ease install, some redesign of how I want to clamp the mesh down, and mechanical testing to see how fast printed ABS can go before mechanical failure. I think we'll be okay on that front considering we're racing (W2W!) printed ABS bumpers, but we have to check.
After the last few months of work and rework on what's effectively just seven lines, it's super rewarding to see stuff like this finally happen.

It may be a GT3 cup decklid with bodywork done to smooth out the edges to make it look prettier. Haven't see one like in your pictures, but it looks good.

The regular cup deck lid would maybe be a better starting point as you don't have to deal with the chassis mount slots. The cup uprights bolt to the sides of the deck lid and I think you could make that work with minimal body work. Not sure about latch mounting options though.

That's a lot of bodywork to re-profile both the top surface and edge/corner detail on a Cup ducktail. It'd probably be easier to get an RSR decklid, chop the skeleton off, and bond it to the bare skeleton of a normal C2 decklid lol. Just saying, with the RSR piece to start with the only fiberglassing needed is to cover the two slots...
Barring that, maybe we really get a GT3 style decklid and chop the wing off. The holes left where the risers were will need to be filled, blocked, and smoothed, but at least no need to redefine the whole surface and edge.

Someone on EBay has a real deal RUF lower deck lid that looks like it’ll work.

It took me going and comparing RSR Vs. Cup parts to see the bigger rear over hang with the RSR part and now understand what you're talking about.
Look forward to seeing what you come up with here.

Looking forward to hearing about. Looks like it's the rsr lid made without the uprights. Hope it is a bolt on with all the right parts.

Great idea.
I would love to modify my wing; cut the upper wing off at the uprights. I think it’d be just about right proportionally. That’s not going to happen 😎
we just got a FDM printer at work. I think it’s a bit small for printing a deck lid, but you’ve got me thinking.

The problem with a static "GT3 Touring" decklid is that without the GT3 wing element, I bet the GT3 ducktail doesn't reduce lift as well as the factory retractable spoiler. If I copy the GT3 ducktail aesthetic onto the retractable spoiler itself, I can limit the upward travel of the mechanism and you'd be able to match factory rear downforce to avoid upsetting the aero balance. Or, if you have a front aero solution, let it go as high as needed to balance that out (at the cost of drag). All that should be achievable with some simple adjuster "pills" since it seems like the spoiler mechanism works like a window regulator (stop when resistance encountered).
Someone owes me a ton of 3D scanner time for the CFD work I'm doing for them, so I'll soon be able to get a whole 996 body scan and get to work. We could CFD it just for fun, but it would be wildly inaccurate without the engine bay fully modeled so don't expect to believe the numbers lol.

I thought of modeling just the lip and printing that. I have a stock deck lid, but didn’t think about attaching it to the adjustable part of the spoiler…interesting.😎

Managed to extract a GT3 3D model from Assetto Corsa, it's not accurate, but it at least gave me some reference points to start laying out the basic lines. Once I scan my car's butt we can really dive in and make every curve perfect. What do we think so far?
