Can somebody please show me pics of how i need to do?

How big braces etc etc

 

Working on the same project right now.

 

what wing are you adding?

 

I am going with the APR GTC-200. The "recommended" APR wing for our car is the GTC-300, but I was concerned that would be too much weight and stress on the CF hatch.
The 200 will not provide as much downforce, but there is a Gurney flap which can be added if necessary.

 

BTW, there is some useful info here

My plan is to attempt to add some front splitter support rods like in post #17.

 

Im going with the Voltex Type 3.

1700mm

 

But my hatch is to soft anyway even with that kind of rods.

the whole thing flexes with just a little finger pressure

 

My hatch is Seibon and that feels pretty flimsy too. I'm going to try to anchor the splitter rods as close to the edge of the trunk as I can. That seems to be where it is most rigid.
I'm also going to use some aluminum plates to reinforce where the actual base of the wing attaches to the trunk.

 

im think that a plate just dont do it since my whole hatch flexes.. So im thinking of a big X underneath

 

I'll be switching to a CF hatch after this race season and will probably be doing something like this. Subscribed for results.

 

I went to visit Devari's shop this weekend and they are working on a CF hatch. I think why the other hatches are weak are because they just use a thin layer of fiberglass under their CF. I'll tell Devari about the problems people are having mounting wings on their hatches so that they can make the ones they have stronger.

 

mine is vacuumed dry carbon.. only a thin layer with nothing between or under.

 

wish i could add a GT wing. the sloped edge of my Mastergrade prevents me. oh wells it still looks hot.

 

I have that same hatch... So i have to make custom fotstands.

 

i thought the same as well. not sure how secure it would be or if it would look ugly. are you in the process of doing it? interested in seeing how yours turns out.

 

if you done care about the huge mounting plate theres always the cwest wing that appears pretty stable i dont have any experience with it though *shrug*

 

No i havent got my wing yet, Or found someone that can help me with any of the things ive planed on getting made.

Fotstands and the inforcement-part in alu

 

Wing installed on CF hatch. It may not be the most esthetic way to do this, but it works!!! This thing is absolutely solid.
On the outside, additional support is provided by splitter support rods. They are adjustable, so the wing angle can still be changed. On the inside, I have 1/4 inch aluminum plates.

 

Finally some pics! Great!

So those two smal pieces is good enough? I dont need a big plate from side to side? Not bad.

How wide is your wing?

 

I figure when i get a GT wing i will just have standoffs welded into the actual trunk and make it so its quick and easy to remove to wing to open the hatch. Something like that will be the best bet.
