EVO9 Wing Failure/Track Related/ FYI

Just happened this Sunday
Winds were howling at the track (50-60mph gusts). Been to this track many times w/no issues, same wing.
Recently added a wicker bill with the thought of adding just a bit of down force(First time to the track w/it)

Anyways, 4 laps into the stint, I look in my rear view mirror to see my stock wing vee'd down into the trunk
When it snapped it dented the truck surface. Anyway, garaged it & removed it to complete another stint which felt very loose

All in all, a loser day for me. Damaged wing, dented truck lid, cracked windshield & lost a magnetic no. 1 somewhere

Whoa, that's heavy Doc! (Duh dun tsss).

What kind of speeds were you reaching? I personally wouldn't call the evo wing weak, I didn't think you'd be able to reach levels of downforce that could break it.

I didnt think so either. A while back some member posted a story of a guy breaking a stock wing at the track. I personally posted that a failure like that would be unlikely IMO (foolish me)

Todays main straight speeds where slightly muted due to the high winds. I was running at 135-140mph

I didnt here it snap, but when looking in the rear view at a slower section of track is when I said ??^%$#O((

looks like a larger wicker bill then i've seen previously installed on our oem wings. Evo 8 or 9 wing? the 9s are weaker than 8s. with the high winds you stated and your 130-140 mph speeds on the straight...this could happen.

sorry to see this happened to you!

One of our local friends has had his evo 9 up to high speeds in Mexico several times and has broken his evo 9 wing exactly the same way. The 9 wings aren't as strong as the 8 wings.

Evo IX wings are insanely weak. I was borrowing a friends IX wing when I forgot my Evo 8 wing at home and during the higher speed turns at the track the wing was shaking quite a bit when I was doing around 110mph Been running an 8 wing for a couple years outside of that one event and I have not had a single issue with it I've gone to the same track that OP has and I have hit 150+ with zero issues

Auto Club? The three days I've driven there, the winds were crazy each time!

Wow, sorry to hear that. That's just nuts! Luckily the car didn't get unsettled in the process causing a close call!!

Now that I think about it, 140mph and 60mph winds can make 200mph air speeds (in the right direction) and with that extra bit of downforce from the wicker bill, it would have been a pretty serious amount of downforce. What are your chances of claiming under warranty?

That I did not know. I'd ask why the 9 is a lower quality than the previous model but I don't think I want to know. :sigh:

Someone can correct me if I'm wrong, but aside from it not being full cf like the 8 wing, I believe the center of the 9 wing is hollow and the center of the 8 wing is solid (idk what's in it to make it solid)

My good guess is: polyurethane foam

Your absolutely right, the 9 wings are completely hallow where the 8s are solid but not sure what material is inside it. You can google it and find alot of pics in the defference of both wing cut in half. But sucks that happen to your wing.

Damn, so sorry dude!

So, the rumors are true. Guess I can't be in denial anymore!

Well, I guess if this happens to me I'll have to move up to a different aero set-up or get an VIII wing.
