Thanks! I had no idea the sides were different between the 8 & 9. Mine are CF so looks like I have the 8 spoiler.

 

ugh.more issues to address you guys sure the IX wing can be disassembled? i will try to put an aluminum pipe/bar in there. I just cant go with the full race car wing

 

Its can be disassembled easy, this would forsure solve the problem other people had with the 9 wing failing however I have been using mine with a gurney flap for a long time at high speeds against very powerful winds and its never failed. Also have the vortex gen.

 

probably down slope winds? I'll add this to my to-do list. Thanks

 

Alrightey gents, The wing is off the car. I can't figure out how to disassemble this, Any tips? Thanks
If all goes well, is there anybody that sells a riser for this wing? would be cool to make it work a bit more

 

@ViciousLSD This thread should help: (looks like the wing may be riveted & glued to the pillars?)

Thanks!. Heat and Patience... oh boy.

 

Could do a c7 gurney where the middle part is flat.

 

I also wonder if the construction of the gurney flap itself contributes to wing failure. MinusPrevious, I noticed yours was some cheap ebay material just taped onto the wing. If it were a strong, composite carbon flap I wonder if this would have added strength to the wing and kept it from failing.

 

Im sure that trunk lip may have contributed, but i know now the 9 wing really does not belong on a proper track day EvO. I certainly learned a few things tracking the EvO.

Weak links (mechanically or aero) are certainly exposed

 

@MinusPrevious @RallySport9

well OK. I got it separated I used these wedge tool thingers. I tried separating the CF but it looks to have a couple of studs inside ok off to Lowes tomorrow and get some aluminum/whatever tubes & expanding foam. I actually have really thick galvanized wire so that a lighter option. Should I put supports (ex:5mm tubes) on the leading and trailing edges OR 5mm trailing edge + 12mm tube somewhere in the middle? I also plan to make a 2" riser later

 

Well done! If you can take a few detailed pics of the CF wing ends that might help those who attempt this.

I would think if you can just fill the wing w/some high density poly U foam & make sure it packs in full. Dont allow the foam to stretch out too much as that weakens the foam structure. Keep in mind there are many different foam formulations. Structural foam vs home insulating so please check around (I would use a min of 4lb density foam). There are spray foams & there are foams you can mix on your own.

That foam should be enough to withstand track speeds? But adding those tubes, as you noted, could add some structural strength if they were placed tightly in the wing (but, likely not needed for sure)

In any event you are doing something most EvO owners have never done so this is unchartered territory in my book. This should be its own forum post if you complete it to your satisfaction

 

 

As you can see, the trailing edge is pretty thin so I dont think any foam can add much strength to that. I see foam to be more of an adhesive that will "triangulize" several points on the CF, so light foam would be ok (as long as it adheres to the CF) and just enough to keep "tubes" from rattling. Note that I'm raising the wing eventually so I need something stronger than evo8's
I might visit Academy Sports to see if there are any material I can use
Thanks

 

Nice pics & thanks. I understand better how the wing was constructed. If you want, you can make a new thread to support this tear down & re-construction? Its up to you or i will change the title to this thread so it can be found in a search

Thanks, Joe
