DDMotorsports: Kognition Design Wing Development
 

Hey everyone! Just wanted to start a thread for this since there are a few track junkies out there with 370Zs :). The DoubleDownMotorsports.com Time Attack Project 370Z is in the hands of the very talented Kognition Design. Kognition design was responsible for the dry carbon hood, doors, front splitter, and canards on my old time attack 350Z and his main focus now is producing increidble dry carbon wings that can already be seen on some of todays top winning time attack cars like JC Maynet's Harman Motive Subaru STI, PTuning's Scion tC, and JIC's Porsche GT2. He is making a production version wing that will be specifically designed for the 370Z using my car and this will be the thread to watch the process!

Here is the first step! The stock spoiler has been removed (and left a bunch of holes in its wake :mad:) and the locations for the wing base have been chosen...

The wing final design and specs of the wing will be decided shortly as we are waiting on the 2010 Redline Time Attack Rulebook to be released later today actually. We want to make sure the new wing fits within their Street Class rules.

YAY!!! I am glued to this thread and cant wait to see the Progress :tup:

I cant wait to see how the your Z will look in the end of the project

Me too. I really really want to get a little more agressive body kit, like the Nismo or something but budget is not there. Trying to find a body kit sponsor, but that isn't going well either. I think if the rest of the body kit looks a tad more agressive and aerodynamically functional it would compliment the wing even more. The wing will be amazing though. Kognition's work is incredible and I have seen his wing elements and they are :drool:

in for pics :)

Here are some photos from Kognition to show his work. These aren't of my wing just other wings he has done...

Wing for the JIC Time Attack RX8. This is not the normal weave pattern he uses...

Then here is the mock up piece of his new adjustment design. Really cool design that allows you to easily adjust at the track without having to measure and re-measure to find your angle. Just pull the pins out and move the wing to the desired position and put the pins back in. Adjustments are made in incriments of 1 deg.

Then here is a diagram of it...

And a closeup of the dry carbon weave that he usually uses.

The 370Z wing will be made to fit within the street class Redline Time Attack rules which mandate a max width of 68" and a max cord of 14". It can also not extend back past the rear most part of the car, and cannot sit taller than the tallest part of the car. Plans were to build within those specs anyways as the car doesn't need much more than that.

Wing stands are getting water jetted today! Mold making process starts tonight :). Hopefully we will get some more photos soon.

Sounds promising, keep us posted!

Honestly though, I think I'm gonna shy away from huge wings, even with its functionality. I'm thinking a nice CF spoiler like the one from the FRP package will complement the car nicely, especially when I'm done with it :) Doesn't mean I can't appreciate the DDM car when it's done though

Thats Awesome! Kognition is quality stuff!

Keep us posted, can't wait to see it on the car.

Only Z34 i've seen so far w/ GT style wing is SLR Car.

Look's like they tried fitting a Voltex Z33 wing

Thanks guys! Big GT wont be everyone's style but for me function is sexy and this wing will be incredibly functional, built specifically for the 370Z and specifically built to the Redline Time Attack Street Class (or Street Tire Class for 2010) rules. :)

Speaking of...Paul, when are you bumping your Z34 up to Street Class to keep me company? :) I was actually going to run in Stock Class for the finals with you but this wing puts me back in Street.

Cool, you know I'm in ! :)

I think the rule on Redline TA Street are pretty consistent with other series... it's a good spec to design to... and as you say, probably all the car needs, especially when paired with a functioning undertray/diffuser

One thing I like about the sunline racing setup is the possibility of running two airfoils... wonder if given the design limitations you guys are setting about following (width, cord, height, outrig) if we could run two foils within that... ?

Also, what trade-offs did you consider on mounting point ? seems like the logical place to mount it, but wondering if there's a 'harder' surface to connect with somehow ???

New photo!

These are just mock up stands. The final stands will be waterjetted, not solid in order to reduce weight. As you can see he changed the mounting location for the stands but is still finalizing the design for the bases, but they will end up being fairly large to disburse the extra load the wing is forcing down evenly across the hatch to minimize flex and make sure the hatch doesn't get damaged.

Lookin' good.:tup:

Will you fill in the holes from the stock wing, if so what is the best method?

I think once the bases are done, only the middle three holes will be left. I will have them filled and painted professionally because I am picky and my car is going to SEMA. Kognition did say that those little round plastic clips from the engine bay do fit in there and a small bead of epoxy will seal it from water, plus I am sure that you can find lower profile plugs at your local auto parts store that will work and you can even paint those to match your car.
