Targa roof SAFETY ISSUE

I have a serious fault with my car which has been converted to a Targa. I would be extreemly gratefull if any GT owners of Targa roof cars would contact me urgently by email even if you have no noticable problem, but obvoiusly if you have a problem with your car. In particular im interested in the overall fit of the roof. Also the allignment of the door gaps, and the fit of the windows.
Pls all readers of this message contact any known members who have Targa's, and ask them to e-mail me.

I have had 2 engineers reports done on my car and both indicate serious safety problems, im waiting for the facts in writing before advising in detail the problems. These i will post here next week.
Many thanks

I don't have a targa, but I HAVE reinforced a GT chassis that is a convertible. What problems are you encountering?

Reinforcement

I bought a kit for my Gt to make it a convertible and it was really junk. I purchased it through a guy I think in New Mexico, he always advertises in the Blitz magazine under the name C.A.R.S. I had to basically build a ladder frame.

Help Reqd with Legal action (LENK)

Re my previous post, Subject; Targa Roor Safety Issue.

Story so far:
I live in the UK and own a very good modified 1971 Opel GT............1999 Modified Concours winner National meeting.

Still wanting perfection i start looking into converting this car into my dream car. Requirements are
New leather interior, side skirts, front and rear spoiler, uprate brakes and ......Targa roof, and of course a full respray.
This car is very rare in the UK due to the fact that its a "left hooker" and there are no specialist companies in the UK with knowledge of this car.
When i make enquiries most advise that Lenk in Germany make a Targa kit fot this car which is TUV approved, they have sold many of these kits over the years and their 3rd version is the business. I contact Lenk and arrange to drive the car to Germany for the work to be done. Quoted nearly £12,000 UK pounds total. Vehicle will be finnished in appx 8 weeks. Stage payments were made,with a balance to be paid on collection.Appx £2500.

See Part Two

Legal action Part TWO

Some 16 weeks later i am advised by Lenk that the car is finnished and i arrange to fly to Germany and collect it on a Sat morning. On arrival the car im informed is not quite ready the doors and windows need adjusting and the Targa roof need finnishing. will be a couple of hours. Still not finnished 7 hours later,told to come back next day. Return next day and watch the owner Gerry try to adjust the windows, it was pathetic to watch.4 hours later he was still trying having drilled many holes to " get them right" in the end he said that he was too tired to continue and that i would have to get the doors and windows adjusted when i got home. It was quite apparent to me ,and i do not know that much about cars that the was something wrong.The way the doors fitted and the windows wouldnt close, meant i got soaked driving the 18 hours home to the UK.
Gerry at Lenk totally denies that there is anything wrong other than minor adjustments to the doors and windows.
I have since had the car inspected by 2 different engineers and have recd their reports.
Both reports state the the strengtheng to the chassis is totally inadequate. As part of the inspection the car was lifted by four pads placed under the rear suspension and front jacking points
As the car lifted there was a noticable "click" suggesting movement in the bodyshell was taking place as loads were distributed from the wheels to the jacking points. As the car was lifted the NSR door gap opened by about 4mm indicating excessive flexing of the bodyshell.As the car was lifted the front gap to the Targa roof opened by about 5mm indicating excesive flexing of the bodyshell. The engineers both state that the car is not roadworthy and therefore insurance for the car cannot be obtained. There are other problems , large areas of paint are not bonded to the lower layers. The car needs a total respray.
The cost of getting the car SORTED is Appx £10.000UK pounds
What would you do if this was your car??
Have you or other GT owners had one of Lenks Kits fitted?
I at present getting together the documentation to make a case in order to take Lenk to Court
As Opel DID build a propper Targa the AERO i wondered if anyone has information or a drawing of how Opel Re-jigged the chassis.

If anyone is able to assist pls e-mail me [email protected]

It is some 5 months since i notified Gerry at Lenk that there were serious problems with the car. I suggested that i would pay for his nomminated representative/Engineer to inspect the car. I also notified him again 2 weeks ago that if i recd no response from him or his company that i would have to resort to Legal action. He has failed to respond
Would you buy anything from a company that treats people like they dont exist??????????

Regarding the "factory" Opel GT targas, these were in fact vehicles built for show. Reinforcements were not sufficient, as both cars apparently later on had problems with chassis rigidity. So using them as an example may prove futile. Here is a photo of the underside frame connections I added to my father's own convertible G. In addition, 12 gauge steel inner rocker panels were welded into place, and the entire rear "seat" area was boxed for strength.

Legal Action against Lenk Germany

Many thanks for your reply, this info may prove usefull. Do you know of any other vehicles that have had Targa roofs fitted, and were they Lenk kits? What i need to progress is evidence that there are problems with annother car. Taking legal action is very expensive as the case has to be in Germany and i have to pay for translaters etc... The cost to me has been estimated at £ 12.000 UK POUNDS. Then when i win the case, i will then probably have to go to court again to get payment.
What would you do in my situation, any advise would be appreciated.
Thanks.............Malcolm

Has anyone installed the Targa Kit from OGTS? How did it work out and how much did it end up costing in the end? Also, did it compromise the frame at all?

I am based in England, and wanted to fit a Targa Kit to my car. I decided that i'd let the experts do it. I used OGTS's partner in Germany LENK, to do the work, using their so called TUV approved kit, they state that this kit makes the car stronger than the origional. I paid LENK in Germany over $15000 US to convert the car to Targa, respray the car and fit new brakes and interior. The interior and brakes are excellent but the Targa is totally Fu..ed. This kit which is supplied to OGTS by Lenk is not strong enough. The car flexes far too much. When lifted on a ramp the gap between the targa and the body opens up by over half an inch. The door gaps are then also way out.
I had two engineers reports done on my car and both state that the car is in a dangerous condition, and is not roadworthy. The U.K. Ministry of transport have checked over the vehicle and come to the same conclusion.............this work has seriously weakend the car. I cannot drive the car and cannot get the car insured.
I am in the process of taking LENK in Germany to court.
I am also trying to ascertain if they LENK realy have got TUV approval as almost anyone who has seen this kit doesnt think that it is strong enough

I have had to give the car to annother company to correct the faults . They have made a special jig for the car and have added strengthening to the chassis by welding in longitudinal sections in place from rear wheel arch to the front wheel arch, both sides, adjacent to inner sill Section . Welded on the A post and B post and fabricated in the vehicle's bodywork caused by the conversion
this work is costing an addional $ 13000.

SO OVERALL I WOULD SAY BEWARE fitting this kit...........Get a engineer to look at it first.

You can see my car on this site in the photo gallery................. looks a million dollars from the photos.................but i can assure you it is the pits close up.

I saw some of your earlier postings when I did a search. I was hoping to get a few other opinions on the subject...not that yours isn't valid. I have serious concerns about the effect to structural integrity, but by the way Lenk describes it, you could strap a Semi to the back of a Targa converted GT without any problems. I believe the exact words in the OGTS catalog is "with the Targa kit properly installed, your GT will be even more structurally sound than a stock GT," or something close to that anyway. Any other opinions in GT Land?

I think that the most overlooked criteria is the condition of the GT that is going to be modified. If, for example, the car is a rust-bucket, then essentially a complete restoration is necessary prior to the addition of the reinforcements. Finding a rust-free shell as a starting point has its' benefits.

Although I haven't done a Targa conversion, I have reinforced a GT that was made into a convertible, and it required a lot of thought and time to do. It's far easier to reinforce the car BEFORE any cutting is performed, whereas in my case I had to jig the chassis first, THEN add reinforcements. I added box-sections of 12 gauge steel plate to the center section of the car, from the tranny tunnel back to another boxed section between the rear wheelwells. I also added frame connectors, cutting the floor to inset them into the sheetmetal there and welding them in place, and connecting the rear trailing arm forward attachment points to the rear of the GT framerails at the tranny tunnel. I also had some 12 gauge steel plate rolled into the shape of the original inner rocker panels, and plug welded them into place there, as well as seam welding them to the floorboards.

Lastly, I added a roll bar, which had a main hoop attached to the front edge of the rear 'seat' platform, with one diagonal brace within the hoop. I added rear tubes to the area directly above the rear coil spring seats. I also added bars from the main hoop that go horizontally back to the rear 'firewall' area, and one diagonal bar on each side from the main hoop down to the reinforced rocker panels. This acts as side-impact protection in addition to tying the front and the rear of the car together. With all these reinforcements, the car can be jacked by the center of the rocker panel, and the doors open and close nicely. Previously, the door gap would open to about a 3/4" gap, and there was NO WAY the door could be opened while it was under stress.

All in all, I have about 80 hours of welding/reinforcement into the chassis. Remember you can't have too much reinforcement, but you CAN have too little......

cool weight

One mor thing about "too much" reinforcement is that it is almost all below the axle centerline and between the wheels, a formula for improved handling to boot.

I'll bet that convertable is a blast to drive too.

Sorry no real update on this issue at present.If you look at the pics of my car you will see what appears a very nice car. But i can assure you it isnt. If you go to page 2,3 and 4 you will see that the whole work has now been done correctly with added strengthening. The car has since rec'd two white undercoats and two topcoats of red, and the whole lot is being put back together in the next few weeks................i'll post the pictures arround Christmas. Total cost of re-doing all this work appx $14,000.
Legal action against LENK is going ahead and i should get them into court in Germany sometime next year..............Lenk will pay dearly when i win the court case.

I heard from Malcom about 3 weeks ago, He's just been doing a full NUT and BOLT restoration and was just about to pick the car back up.

His new webite is going to be http://www.myawesomeopels.com/freespace/

It looks like it still under development, but it should be the final destination for this new vehicle. (Super-highway wise)
