Default Spoiler/wing downforce

Does anyone know the difference between the downforce generating by the STi wing and the WRX spoiler? Also, are there any aftermarket carbon fiber deck lids for the WRX with a more subdued but still functional lip spoiler? If not, I may see about having something like this fabricated. I'd like the functionality of the downforce from the STi wing but would prefer not to have some as obvious as the wing nor the sense of something in my rear visual field and the WRX spoiler just doesn't do it for me.

before you get flamed...check out the big wing SOA please read thread. Plenty of relevant info, speculation, and opinion, but no hard numbers. oh, and plenty of flaming.

Good luck

Yeah, like Rob said. There was a huge ugly thread about downforce. But the short answer to your questions is: No one knows what the downforce of the wing on either car is.

I've always thought the WRX spoiler was something that decreases lift at higher speeds, not something that creates downforce. You know, just to keep the ass-end from getting to drift happy at higher speeds.

The STi wing should produce downforce, but I have no idea how much or at what speeds.

The wing decreases lift by applying downforce.

Not necessarily. Eliminating lift and creating downforce are two different things. Eliminating lift can be accomplished by simply changing the airflow pattern over the rear of the car. That would eliminate lift, but not create any downforce.

OH NO NOT AGAIN.

If you look at the huge thread there IS wind tunnel data for the regular WRX wing. Nothing for the new wing though. I'm not getting involved in another flame war here...

Yes, I remember at above 80mph, it created some downforce in the back, and created a bit of lift up front. The numbers I do not remember. Oh, and induced no additional drag compared to wingless WRX.

The STi spoiler is different to the Prodrive one, therefore the numbers you posted are not relevant except as comparison when we get some public info on the 04 STi aerodynamics.

I am confident the STi spoiler generates "big" downforce.
