Currently eyeing:
Ducktail: TWL Carbon - Carbon Fiber Duck Tail Spoiler (Cayman / Boxster 718)
[video]:

Diffuser: GTS 4.0 Rear Diffuser Upgrade
Any other recommendations, pictures, videos?? Let me know!

I'm honestly quite surprised there isn't more spoiler options (unless you want the monster GT4 wing)

I would rock a duck tail if they made one non carbon fiber and a bit bigger.

I mean its not a JDM car with a crazy amount of exterior and interior mods. Might want to look at a front splitter if you add a ducktail for front rear balance otherwise the front might get unnecessarily light even at highway speeds

 

[Scrounger]

Not for me I'm afraid. Porsche take their aero quite seriously and adding a ducktail may change the balance of the car at speed making the nose lighter.

I did the TWL ducktail, and then with concerns like @Scrounger I bought a front splitter there also. Then, because I got the TWL splitter and I was like WTH I might as well give Bernoulli the best chance I can so I bought the TWL diffuser. And my car really feels solid as a rock at speeds over 100 mph. However, if I could transport myself into the past and do over, I think I would have done the Suncoast Areokit Package and would have saved myself a thousand dollars AND had a center radiator thrown in for good measure. I would have had some parts painted. I'm happy still, and really haven't needed the front radiator, but I think I would have had the same effects.

Your car looks good!!!

Unless you are looking for a Cayman, then just get the Spyder duck tail spoiler.

It's been on my mind but I don't know if a minor duck tail will imbalance the car? I'm thinking of adding on the GT4 diffuser so the minor extra downforce should get compensated by the minor lift of the diffuser

Look great -- but yes I am looking for Cayman!

I'd take this super seriously for any GT4-style wing but ducktail? Meh..

If the diffuser is causing lift you definitely have a problem….

The ducktail looks great!! No aerokit for the 4.0: Aerokit & Spoilers

That splitter looks a bit out of place to my taste - but might look for other options if the lift concern solidifes. Rn I'm not too worried.. ducktail is pretty minor change

This might be my own un-education on the matter. Do diffusers also create downforce?

I've seen two other whacko options from SD Carbon and Moshammer - both are adhesive installs -_-

Why else would they be fitted? Higher velocity air reduces pressure, the diffuser is intended to draw the air more quickly from the (flat) underside of the car creating a low pressure area and hence downforce

If im doing both a diffuser and a ducktail.. then definitely might need to explore a front splitter as well. Good to know.

 

[Wiscombe64]

If you look at the profile of the floor of my race car you can see it’s shaped like the underside of a wing. The diffuser on a 718 is far less extreme but the concept is similar.

How fast do you intend to drive? Unless you are traveling well into the mid-triple digits, you would not notice any discernible difference. For reference, I have not noticed any difference whatsoever up to 120-125 MPH on my Boxster GTS 4.0.

Front lip, duck tail, and rear diffuser here, no problem at 140+ on the track, felt rock solid. Also TWL...
