nice pictures!

 

Can't vouch for the amount of downforce but it has to better then stock and it is certainly in the looks range for you.

Sorry it's a ebay thing only place I could find it in 2 minutes

Hmm.... I doubt the OE spoiler provides any downforce. I think if it has any functional purpose at all, it might possibly reduce the coefficient of lift on the car by breaking up airflow that would otherwise be creating lift.

Think of the lip spoiler added to the TT, probably does nothing for downforce, but keeps it from becoming a flying car at high speeds by reducing the coefficient of lift.

Back to your question, I doubt anything subtle will produce the effect you're looking for. From what I've heard, you have to be travelling at rather high speeds for effective aerodynamics to work properly, and even those aren't subtle.

 

If this is the case for his buying decision then the OEM would probably fit well, In my opinion.

 

My car always felt rather floaty at anything over 130. A couple years ago I added the OEM rear spoiler. Now it feels much more planted and controllable.

 

Interesting, I never thought about it that way. No lift through breaking of airflow might be as effective as having a spoiler which creates downforce (which fights against the lift) to a certain extent. Although an aggressive downforce spoiler can be tuned to create net NEGATIVE lift on the rear wheels, which is desirable on tracks where traction is the limiting factor, not top end speed; a zero lift spoiler with no downforce properties is also effective in keeping the rear more planted at high speeds (albeit not to the same degree). I just wonder if we really get close to zero lift with the tall middle section of our car (because of the airfoil effect).

I did read that the OE spoiler was wind tunnel tested. I just don't know what the results are! I might just believe the last poster's subjective impressions.

Anyone else have any experiences they can share with the OE spoiler?

 

Is the Feels Type 1 a functional spoiler or just for looks?

[QUOTE=i_heart_my_DB8,Jun 9 2005, 04:21 PM] Actually, you cannot use a downforce spoiler to create NEGATIVE lift.

 

I'm still waiting to have someone say if the OEM lip does any good or not.....I don't have anything on my trunk and like the very small lip/spoiler. but I hate feeling....floaty? at higher speeds. If OEM helps at all I'd rather just get that then something large.
