My bad--I was thinking that the 'cross brace' in question was more in the shape of an X (right side brace bottom bolt to left side upper bolt, and left side bottom bolt to right side upper bolt) rather than a strip of metal underneath the wing support.

 

That looks like a really small piece though ... I highly doubt it'll increase the rigidity of the trunk just like that. A thicker and wider washer would do the same job.

I have a CR wing, and I've tried pushing and pulling the wing quite hard. The way that the trunk flexes would not be any different just with that thin sheet metal. One would need an X-brace type of "thing" to reduce that flex (there are a few of those custom ones on this board I believe). But those braces are much more heavy duty than this 1mm sheet metal ...

 

Yeah, I wouldn't consider that piece a true reinforcement. It's more like a strip to spread the force generated by pressure on the wing across a larger surface area. Not really any different from using a large washer like Ks320 said.

 

from what i heard from my friend that has a cr wing installed that little strip of metel does make a differance. hes a retard and used teh winf as a handle to open/close his trunk and put stress "dents" onto his trunk.
after he noticed it he wnet to honda and ordered a cr trunk and it doenst do that anymore. well it may be due to him not using the wing like a handle.

that strip is not huge but it is not small and spreads the stress from the wing over a much larger area than a large washer would.. but dont take my word for it. just telling u what i heard from a friend..

 

maybe its not just a sheetmetal but something else. Or its shaped in a way to make it strong and extend to where we dont see? I dont know no personal experience.

 

thats what she said!

Well ... unless that sheet metal on the CR trunk is made of spaceship titanium or something ... I can't imagine it having any substantial difference

If you look closely at the CR trunk in person, there are no extra bars or anything. you'll notice that there are more "holes" on the underside of the trunk lid. You can see that there is nothing else extra there.

Besides, if you really wiggle the crap out of the CR wing, you'll notice that you actually do need a bit of force to really flex the trunk. As far as I know, the wiggle-ness of the CR wing on the CR trunk and on mine is quite similar ... Also, force from wind resistence would be far smoother than the force applied by a human testing the wing like that. A more realistic way of telling the difference is pushing the wing at an angle from the top. With that, the CR and my trunk react the same way when tested using my hands. anyway, I'm using some very non-scientific tests here, so I could be wrong.

I'm just saying that there is no apparent substantial reinforcement that could come from those sheet metals.

The reinforcements that actually make a difference on the CR are the rubber / plastic stubs. The S2000's trunk doesn't close THAT tightly, and those stubs help the trunk to close more tightly, and prevent any rattle / movement of the trunk at high speeds. The funny thing is that ... Honda actually don't have those studs for the TypeS, and only put those for the CR, even though the aerodynamics are supposed to be the same for those two!

 

so the CR wing will fit...say a 2004 S2000? cuz i bought one for my 04 but it doesn't look like the screws will fit. Do you have to drill through the trunk's supporting bracket that is under the trunk?

 

you can also buy a seibon CF Wing

i have one.easy to install.i hit 270km/h(167mp/h) and had no problem and i can feel the difference in stability.
