Has anyone had any problems with there spoiler cracking? If so what did you do about it. Its the part where the top of the wing connect to the mounting piece before the bolt on to the trunk. I will try to post a picture later.

 

Here are the photos. It's kinda hard to see.

 

I just finished sanding and prepping the wing for a repaint with a different "addition" for carlisle. See ya ll there.

Noted no cracks but can tell you that the inside of the wing has honeycombed support material to stiffen it. Its hard material and seems to be really strong all the way to the mounting pedistals.

Enjoy, Woody

 

very common problem on the SRT6 roadster, and seems to be a design flaw ... speculation is that it is caused by high speeds, perhaps from the downforce

however, nobody has ever had one fall off ...

 

bmorgan has talked about his wing cracking but i'm not sure what he did to correct it......you might PM him and ask ,,,,,good luck.

Mine is still cracked. I have not gotten around to checking ointo getting it repaired. Here are a couple of pics of mine. As you can see, mine is cracking in the same place as yours.

 

What did the dealer say?

 

Both the wings were replaced on my 2 roadsters. Both have cracked a second time. Aint life grand?

 

Its more than likely the result of road vibrations/body movement, combined with the forces from the downforce the wing creates

It seems to me that on the roadsters, the wing is very long (front to rear) and putting that huge surface on the end of long standoffs only increases the torque effect it has on its mounting points (torque = force x distance) I would say that a fix would be fabricating aluminum standoff brackets for the wing.

Initial investment might be a little on the high side but it would still be cheaper than buying and painting new wings left and right

 

well i have a hardtop, with 36.000 miles
after waxing it for the first time
i noticed i have a [vertical hairline fracture] on the wing post on
the passenger side .. it almost looks like the paint is cracked..
oh well it still run's great.

 

No cracks on my coupe.
But do have cracks on the roadster.

 

You guys are making me nervous... So, I went out to the garage and
checked my coupe. So far, after 87,000 miles of hard driving, no cracks
yet. But you can bet that I'll be checking every week when I wash the
car.

Happy B-Day America!

While we're speculating on the cause (mine was cracked too - replaced it last fall), I would guess that the most likely cause is slamming the trunk lid. Considering how many have cracked, I find it hard to believe all of those owners have driven it fast enough to produce the kind of downforce necessary to produce the problem, and I would think one hard trunk lid slam would produce a tremendous amount of force on those wing struts, considering the amount of overhang of the wing from the mounting points.

I know I've been very gentle when closing the trunk lid since I've replaced the wing! I would recommend others do the same...

Just my $.02 worth...

 

That's why I don't slam mine.

 

This has been suggested before in another thread on this subject. I will re-itterate what I have said before. In my case, I do not use my trunk. It is a weekend driver, and the couple of occasions that I have opened the trunk, it was closed gently. I have never used the car for shopping, long trips, or anything that would require storing anything in the trunk. I think the only thing that has ever been in my trunk was a racing helmet.

While this seems like a logical reason for the cracking, I can assure you that is not the cause in my case. I really believe that it is a design flaw in the roadster wings.

 

the roads here in Knoxville TN are chitty,
so that being said, bad roads more than trunk slam
but i do bet that the trunk slam , and wing mount. plays a part though

 

Whatever causes it for all of us who have experienced it, I totally agree it is a design flaw where the designers did not take into consideration some common forces that end up being applied to the wing. I didn't mean to imply otherwise, nor was I accusing anyone of slamming their trunk.

I was just suggesting that slamming the trunk too hard (by anyone - a previous owner, a service person, etc.) seems like it would be a very common (and easy) way to exploit the flaw. Maybe hitting a really hard bump is too. While I agree that there must be some downforce at very high speed (but little at low speed - the downforce of a wing varies with the square of the velocity), not everyone with cracked wing mounts drives their roadsters 150 mph, so it just seems to me that high speed wouldn't be the most common way to exploit the flaw.

However, when you drop something, even from only four or five feet, the deceleration forces when it hits the ground can be very extreme. Add to that throwing something at the ground (or throwing a trunk lid shut), and you can see where I'm coming from. Laptop hard drives designed to withstand a short fall are typically rated at hundreds (or thousands) of g's (It's not that fall that kills you - it's the sudden stop at the end). The trunk swings very easily around the trunk hinge pivot point on the roadsters, and wing is out at the end of that swing, and the wing's downward force has more leverage on the mounts on the roadster when it suddenly stops than on the coupe, because the mounts are longer.

The mounts should have been made stronger, since many are cracking, whatever is exploiting the design flaw for each of us who have experienced it.

There is probably a g-force measuring app for an iPhone - one could tape the phone to the trunk lid, then...

 

There's another cause - a local paper reported recently that two boys were caught jumping on "wings" at night to make them break! Now that would cause a crack!

 

Where were their remains buried?
