Wing is slated for release by end of Dec.
This wing looks great . Not easy to see from pics, but it seems it has all the right attributes regarding effective functionality .

Has it been wind tunnel tested? Any numbers regarding downforce (or reduced lift)?

When you get to that level, I guess the only other thing left to do is an $8000 wing.

Not really sure how much driver mod he had though...
This is key. Whenever I think about doing a performance mod to the car to improve track times, I remember the lead-follow exercise we did at a Lime Rock Skip Barber school four years ago. I was driving one of the school's E92 M3s, following an instructor driving a Mazdaspeed 3. I couldn't match his pace if my life depended on it. Show-off.

As Ross Bentley says in Speed Secrets...make the car show its weaknesses. At that point, I think its optimal to mod. I went overboard on my 330 but being more judicious with my M3. I have added camber plates and BBK to address obvious shortcomings.

Everyone, thanks for the info. Basically being a cheap skate doesn't pay here.

If I do add downforce does that wear the tires a lot faster?
