So you want me to believe that a duckbill produces 100% more downforce than a gt250 wing and at the same time produces 400% more drag than a gt250 wing? Might want to check your CFD settings or throw this thing away. ��������

When combined with their swan neck wing it does...

How does your duckbill work with and/or compliment things such as (roof) vortex generators and rear diffusers?

Fluid dynamics, air management, and drag coefficients are cool stuff.

Hows the CFD performance compared to the OEM BRZ spoiler with a wickerbill?

How is it mounted? Fasteners or tape only?

I too would like to see how it compares to the OEM spoiler.

Any paint matched pictures?

Could you post CFD data for a stock car vs a car with this duckbill? The data you've posted seems like it might be with the rest of your aero parts including the wing, but I'm debating adding this to an otherwise stock car, and that data would be useful for many of us I think.

Here are some added CFD images of the ducktail spoiler with our Ventus 2 package.

The FR-S/BRZ does not need vortex generators as the flow stays attached to the roof due to the shape of the car. Vortex generators work more on sedan type shapes to keep flow attached to the more dramatic ramp down of the rear glass on those body styles.

The ducktail would improve/compliment rear diffuser function.



We don't compare our products to other units on the market. However, I have added a graph with the OE BRZ spoiler in comparison on the first post and added below. Our spoiler produces more downforce and drag than the OE unit. This is expected though as it is more aggressive.



It will be attached via VHB 3M tape; which we have seen hold up to some very impressive loads at this point. The dive planes below have seen over 150MPH and are only attached with double-sided tape.

We do not have any paint matched photos currently.



The note on the graph stated the numbers were with our entire Ventus 2 aero kit. I have edited the original post to clarify this. The graph is with our entire Ventus 2 aero kit on the car. The graph was to show the delta (change) between no spoiler and spoiler. I have updated the original post with a graph of no spoiler and spoiler on a stock FR-S to help with understanding the performance side a bit better; which is posted below.

That being said, from our experience in both CFD and wind tunnel testing, our high-efficiency rear wing does produce more downforce than the APR GT250.



That is correct; the data was to show the delta between the spoiler and no spoiler with our Ventus 2 aero kit. I've added a comparison to an OE bodied car above in this comment as well as the first post.

Let us know if you have any other questions :burnrubber:. I apologize for the confusion but we remade the graphs to hopefully clear up the questions.

Based on your own numbers, your entire aero kit produces less downforce than just a gt250 wing while producing an insane amount more drag.... didn’t a guy in 86cup Colorado go a full second slower at high plains with all your aero vs no aero at all? I couldn’t believe it but based on how much drag your parts create vs the downforce, I completely understand now.
