You use to be able to purchase a similar rubber adhesive backed gurney from BMW. I wonder what Rob used...

hmm....curious why the lower plate edge would be better? wouldnt it present a face of wind resistance when turning? no clue why the end plate for the j's is like that though.... any one with a suggestion?
either way, i've been told by my shop that the voltex type 3 will have to use the regular end plate not the j's style one. ugh.

As far as the lower endplate, F1 teams run it for 2 reasons IIRC. One, in order to mount the lower airfoil. Two, the extended endplate keep trailing vortices from developing. The "kink" that was referred to is also present in F1, however, it is to deal with airflow around the rear wheels.
In regards to the J's Racing wing, it appears to me that the "kink" is purely stylistic.

Most of what I know about aero is from reading F1 articles. I believe the primary purpose of the endplate is to prevent the high pressure air on top from getting to the low pressure air below the wing. This interaction would result in drag.

Any thoughts on whether a 195mm or a 225mm wing bracket/mounting will be better? I am thinking of going 225 cos i might get cleaner flow but strangely 195 is what they give on the J's car. Something to do with street regulations? or competition regulation? (personally my car with a wing is illegal anyway so i dont care
)

They are actual Gurney Flap that sits flush to the surface with an adhesive (3M Double Side).
mind if I ask your opinion on which mounting for the Voltex wing would be more desirable? i'm dicing between 225 and 195.

[QUOTE=c32b,Jul 15 2008, 06:01 PM] thank you for sharing...very informative and you've helped me make an informed decision. I will probably just go ahead with the Voltex 3 and end plate A. Pricing is better too

I think that decision is more based on driving style and how you want the car to handle. I don't know if there is a rule that dictates what is "better." Generally, a higher wing will produce greater downforce in the rear, so if you have an ap1 that's prone to snap-oversteer, or you are running a non-staggered setup, you might want more downforce in the rear to help bring the car back to neutral handling.
Given that you need airflow above and below the wing for it to be effective, I would venture to guess that you would want to run the wing roughly around the roof line of the car.
