I have a 911 style hardtop in my 99 like the one on ebay, but I'm not un-biassed as my dad designed it before passing, he invested a few years in designing it and producing the first molds, his vision was eliminating the non-porsche slant shape of the original convertible top and original hardtop.
Basically he designed in the computer and created a sliced frame with a cnc machine then hand shaped the buck until he was happy with the shape. he wanted to keep the original trunk but still achieve the look of the general shape of a 911 and other porches iconic side shape and rear side windows, he did not like the shape of the cayman look alike rear side windows.

The fiberglass is hand-laid 3-5 layers and it is unfinished in the inside (mine is still like that but I will uphoslter the inside soon when I get some time to get to it but I have seen how they do it and is a simple task as they glue a headliner made of foam and vinyl or alcantara-like material.

It is very quiet with no wind noise and no water issues, it really changes the driving experience as it feels like a coupe, at the beginning it had some noises from the seals squeaking over ramps and bumps but I solved that by applying some silicon lubricant on the seals and adjusting the latch a little.

I can remove it in 3 minutes by un-latching it and removing two bolts, the rear window and side windows are lexan with a uv coating so they are crystal clear and wont yellow or degrade and the entire top is only about 40 lbs, the only problem with polycarbonate is you have to wash it very wet as it will scratch easy if you wipe it when dry.

In my car the side windows use the get stuck on the top when opening the doors due to stretched cables as the windows were not dropping enough to drop the glass to clear, with this hardtop the issue went away as they seal nicely regardless.

The fiberglass is good insulator and thick enough that is very quiet and the ac and heat do a great job, I guess it will be even better once I install the headliner.

I had to get it sanded prepped and painted to match the car, the finish is good but still needs work as any top would I guess

I like it a lot as it changed the entire feel and look of the car but again there is sentimental attachment to it.

The people producing it do a good job and they said they can do a discount to members of the forum if interested, they have been selling these mostly to buyers in Europe they are close by to me in South Texas

any other questions please ask.
