Any recommendations for functional deck spoilers for the S550, and how do the Ford spoilers compare to the aftermarket?

 

no specifics from me, but some thoughts:

> a spoiler (wing) needs to be pretty tall on these cars to be truly functional, to get it up into the laminar air flow
> take a look at the GT350R spoiler for an example . . . I assume it is "functional" but the real race cars have even taller ones
> if i didn't want to make a big research project out of it, I'd probably go with FRPP product, GT350R style

 

Whichever one you settle on, be sure it will accept the addition of a Gurney Flap.

I have this one, and although there is practically no way for me to determine its effectiveness, it makes me feel good to see and touch it.

 

I had a 2013 GT Brembo. Early on I took it on a trip that was almost all expressway driving, and even though it handled well, at higher speeds it felt lite. I added a Roush chin splitter and a Ford California Special deck spoiler, and it made a big difference in how the car felt at higher speeds. It felt planted on the road, and was happy with the set up.
Now I have a GT PP2, and while I haven't taken any long highway trips (still breaking it in), the deck spoiler just looks like it doesn't produce much if any down force. I could be wrong, and I'll have to try it out after the break in. Just in case it doesn't provide the stability I'm looking for I'd like to replace it with a Ford product that gives me what I want if I can. So, any thoughts would be helpful.
Bert, Frank, thanks for your thoughts
