Love it, but I have to drive my car on the street haha. I wouldn't be caught dead with a wing like that in my neighborhood. If there was an easy way to switch it on and off, I would consider running it at the track. I personally think that your test was a success. Like I've said before, they call it "testing" for a reason. Time to retest. Remember the goal is not to bend, not just not to break. A wing that bends too much is useless too.

Its easily removeable. Takes an allen wrench and 5 minutes.

Mike

It would be really neat if they designed a low profile wing that slipped over the mounting arms, or used the same bolt holes that you could have for street use.

Lol Im sure its easy to take it off Mike....the holes...not so much.

Mike, the wing looks good. The legs are perfect. Just the top wing and side blades have more shape to them.

Ok, tested the new version of the wing on Friday and no problems whatsoever! Everything is SOLID as a rock . Here is an email that Kognition sent out about it...

"This week, testing was completed at Willow Springs Raceway of the new Variant 1 track wing. The wing surpassed performance expectations on the test car, time attack driver Mike Bonanni's 370Z. We were able to make some significant strength improvements during the testing phase. The main focus was on wing rigidity, and range of adjustability. The wing is adjustable from 5 degrees to 18 degrees angle of attack in one degree increments. Kognition has focused on product performance, reliabilty and ease of setup. Kognition has set out to produce very high quality track wings for drivers looking for every available advantage for downforce and adjustment. An extra value added feature for customers, is the ability to provide custom CFD downforce/drag/HP charts for a given custom wingspan. Customers want more value for their dollar, and we are here to answer the call. With extensive use of CFD simulation, CAD drawing, cnc and waterjetting, Kognition wings are close tollerance wings. Each wing is vacuum bagged on a high precision cnc cut tooling that is 1/10,000" in tollerance. Kognition's founder Mike Mishler, brought this discipline in from the world of F1 racing. "We had to bring the market up to speed and up to par for quality performance wings that can take severe abuse from both driver and extreme environments". All Kognition wings are produced using only 100% aerospace grade structural carbon fiber. And molded using the best vinyl ester resin available. Nothing has been compromised. We are in fact bringing F1 quality construction to the aftermarket. The new wing profile is called the "Variant 1". And is scheduled to be produced in kit form for the following platforms for 2010: Evo 8,9,10 / Honda S2K / Mazda RX8/ Nissan 350Z, 370Z / Nissan 240SX (S13 fastback, S14) / Hyundai Genesis

Looks great... any words to share on how the car felt at different speeds ? did you notice understeer ? time to add some front downforce now, huh ?

Thanks Travis. I will be doing a full writeup on my blog about the wing testing tomorrow and will link it in this thread. It is definitely producing a good amount of downforce though thats for sure.

I have a question on the wing's design. On post 27, it looks like the uprights are attached to the wing with carbon brackets that are bonded and riveted to the exterior of the airfoil.

On post 37 where it shows the final version of the wing it looks like the upright brackets are aluminum and protrude through the wing surface.

Just wondering why the change between the two designs.

M.Bonanni

Hi Duncan. That was one of the design changes made after our first test when the first design broke in two places. The places where the wing cracked were right on the edge of those carbon mounts so they integrated the mounts into the internal structure of the wing. The inner wing structure is designed to transfer the downforce load evenly across the span of the wing. With this inner structure bolted directly to the uprights all of that load transfers straight down to the car. The old design was basically causing pressure points with the load transfering to the carbon mounts instead of directly to the uprights.
