After experiencing blistering and paint cracking on the wing on my GT5, I had a body shop strip it down to see what the problem was. What a revelation! I don't know if any of you guys have seen how these things are built, but they are basically held together by Bondo!

My first clue to this should have been three years ago, when my wing fell off the struts. The body shop then warned me that, although they had riveted it back on, they could not guarantee it would stay because there was nothing substantial inside to which they could attach the struts.

As far as I can tell, there is no structural integrity to the wings whatsoever. They consist of a couple sheets of very thin aluminum wrapped over some kind of a resin core. Once the adhesive holding the aluminum to the core starts to let go, the filler slathered over top starts to crack.

The two pieces of aluminum are not joined in any way. I expect you could easily break the wing in half just by bending it over your knee. The two pieces of aluminum are so mismatched that 1/4" of filler is needed just to even them up. With the filler removed, I estimate that half the weight is gone.

The struts are merely riveted to the aluminum skin.

I took my wing to a custom metalworking specialist, who told me it is so poorly conceived that it can't be made sound. He said it would be cheaper and easier to start from scratch and build a new one.

I have decided to keep the original wing as a souvenir and purchase a new one, in the hope that an aftermarket wing will be more structurally sound. I am looking for some advice on who makes the best, strongest and lightest wings that will mount in the original holes on my deck lid. I need the new wing to be as close to stock in appearance and size as possible.

Any suggestions?

First, I think Detomaso just had the Lamborghini Countach supplier build him some.

I would have thought that they would have been made out of the surfboard foam? Maybe that is too heavy?

Thanks for the insight. I would never have suspected.

I thought the aftermarket units are fiberglass? Go talk to Kirk Evans. He probably has a solution.
I would contact Kirk Evans of Amerisport. Google and you will find the contact information. He probably could help you with the GT5 wing. He imported and distributed the GT5S.

His phone number is: 419-874-0505

He has a reputation for high quality stuff that fits!!

I purchased his low wing with rear brake light - Beautiful. Light weight, well built, no warpage (Also has integral radio antenna). It is the one on this link, http://www.panteracars.com/evan620.html

Peter,

The usual question; How much do you want to spend and how long can you wait?

When it comes to composites Kirk is an absolute whizz, he'd probably lay you one up at a cost but liek everyone he's usually backed up with work.

For strength the aftermarket carbon fiber units are probably best. I don't know if the one PI sells is like their decklid i.e. a CF overlay on fiberglass or a true CF unit. I imagine at the $1K price its a fiberglass overlaid, but at least the CF would strengthen it. Might look good on your black car too, or paint to match.

There was a guy at Monterey with a booth I got talking to and grabbed his card; Robot Racing, he had a true CF one for the Lambo guys. It was dimensionally the same as ours, weighed about as much as a cigarette paper and had a Lambo price tag of around $3K if I recall, but what a beautiful piece. Web site is www.robot-racing.com
Thanks for the tip on Robot Racing, Julian, but their price tag is a bit much for me.

Jerry Sackett from PI Motorsports wrote me today, and advised as follows: "The wings we make are aftermarket (about 30% smaller) Fiberglass or carbon fiber. (will not fit GT5)."

However, I am in luck with Kirk Evans. He is currently working on a dimensionally correct reproduction of the factory GT5 wing, but made of hollow composite which will bring the weight down to around 7 or 8 Lbs. He will be finished this month or early next month. He wrote to me as follows:

"This master wing has been totally re-surfaced and is far closer (symmetrical) side to side than original. This wing will be much lighter and towers will be removable to prevent stress cracking, which is a big plus. The projected cost pre part will be 1200.00 to 1400.00 mainly because the high end laminating procedure I am using to make them lighter and demand is so low."

Kirk sent me some photos, and the wing looks pretty good. I think I have my solution! dancing

That sounds good, I'd appreciate seeing the photo's if possible. I keep toying with adding a wing back on #9178 and have one here but it needs some work and I always worry about the weight additon to the decklid. If Kirk's unit is lighter and can be removed/added easily I'd be more inclined to go that way.

Julian: I will ask Kirk if I can post the photos here. In the meantime, I will send them to you via PM.

Kirk says that his wing will mount using two 8mm bolts per strut (as opposed to four for the factory wing). For my factory four bolt wing, whenever I took it off, I would simply use plastic plugs from NAPA to fill the holes. It looked just fine. The key is to pad the underside of the strut so the struts do not scratch your decklid.

Peter,
I chose the wing for mine because of quality and the end plates are seperate and aluminum, very happy with it. From Pantera Performance in Colorado, 303-660-9897.
Daniel
Thanks again for all the info you forward me, it's great stuff.
Peter,
I believe it's fiberglass, I will look for my shipping info to see ship wt. I will be at my shop today I will take some pictures. My rear deck support shocks did not work prior(still dont)so I cant judge the weights affect.
On another note, Pantera East sell the wheels I like that are 13" rear, what tires fit? there is picture of a black flared car but appears to use pilot road race tires in the rear 345's
