It didn't hurt my decision. I also got a response from APR directly that the GTC-500 is too large for a stock width Evo. They recommend the GTC-300 for stock body Evo's. I'm psyched about the Kognition wing though, it looks like a fantastic piece.

Glad to help, you can't go wrong with the Kognition wing.

Do you have the APR front air damn and front splitter installed currently? If so; post up some pics.

I've got the splitter and was thinking about putting it back on the car; but only if I could attach it to the frame in a few places as well. I'd also like to have it stick out further than 2". Not sure if I'd drill all new holes or what.

I have the front air dam installed currently which has a nice aggressive shelf, but I don't have the splitter on yet. I'll take lots of pictures when the aero is done.

Nathan, In my experience the further you go out with the APR splitter, the more "flex" you will have unless it's reinforced or you have multiple mounting points (even with that, I think it still needs reinforcement)

Here's a pic where you can see a "dip" in the front from the car before the Voltex set up...

Over the winter we're working on the front splitter to really get it low to the ground (like Jarrod has) and be able to take it completely off/on in less than 10 minutes as it will never clear the trailer to load...I'l let you know what we come up with in terms of mounting locations...

Jeremy's splitter has the same on/off function via pins...

Mount the APR splitter so that it sticks out 5" from the air dam, that will get you in the "do work" region of the aero balance based on the big rear wing. With frame mounting, some extra cables and a stiffener under the APR you can hang it out there no problem. You can look through some of my posts to see what I did for mine.

You can see how much it sticks out here.

I freaking love jid2's car. That splitter looks awesome, I'll be talking to my shop to see what we can do to mimic your setup. What side skirts are you running?

Looks like OEM sideskirts with custom extensions he most likely made himself

Glad you went with the Kognition wing. My buddy just installed one on his 280z and it is top notch quality.


I am glad you plan on re-enforcing the APR splitter... You could always go wood lol.
My wood splitter.

As others said I built them, ABS plastic . I had them CNC cut by a local plastic shop. There's usually a place that can do it in any "business" sized town.

I'll be ordering a Kognition next week too, 70". I'll probably build something out of wood for a front end aero solution for the time being until I can design and build something out of alumalite.
