  • My AD355 Spider - Now a coupe build

    Finally after many years of waiting, saving money, collecting parts and the sale of my last kit, I am about to start my AD355 spider coupe build up. I am using an Air Dynamics stretched kit and extended windshield that uses OEM style rear quarters and lower door vents and of course all of the high quality panels that everyone already knows about. The donor is a non running but fully loaded 1986 Fiero SE with a V6 & 4-speed. I also have a lot of real Ferrari parts which will be incorporated into the build. My plan is to use many of the things that I have learned from my previous build of an IFG cloned 355 spider and help from everyone on this site.

    Cutting off the roof section makes for a very weak Fiero therefore stiffening the chassis is a must and will be my first concern. I will be using many of the tried and true techniques and adding in a few of my own. I want to have little to no bend or twist in the chassis under driving loads. I have two engines that I can use; a 3800 super charged V6 or a 4.9 Cadillac alum. V8. The 4-speed manual transmission will be tossed for either a 5 or possibly even a 6 speed. I may even install the engine longitudinally if I get ambitious enough and can make it fit. For the front suspension, I am planning on using the stock control arms, coil overs and stretching the front cross-member to match the width needed. The rear suspension will either use the stock control arm or possibly a bump steer kit. The frame rails will also be moved out to widen the car. Stopping the car will be done with corvette 12” rotors and calipers. The rims are original 18” 355 rims with BFGoodrich directional tires. The top will operate similar to the original and will be weather tight. The interior will look as close to the original 355 as possible and the paint will be black so extra time will be spent to get each and every panel just perfect.

    The first step… dismantling of the donor car….

    Sounds like an ambitious build. Keep us informed with status and pictures.

    PS. If you want to be more OEM, then the roof should NOT be weather tight or even open and close.

        Well alright!

        I have waited a long time with you as well. Please keep me in the loop. I will help any way I can. It is going to be one of the great ones.

          I suggest you do your engine/transaxle swap before you install the body. Everything is harder to access once the body is on.
          Even the longest journey begins with the first step.

            Brastic... what was I thinking!!

            DeLorean00.. yours is that coupe that is coming along rather nicely if I remember correctly, right?

            FerrariFan.. thanks! my plan is to install all of the bracing and then after that attack the engine/trans.

            I will be posting lots of photos as I go through the build. I just started to take the Fiero apart and there really isnt any point of taking to many photos of that...

            if anyone needs any Fiero parts let me know BEFORE they get tossed in the next week or so.

              Wow, you are pulling apart a perfectly good fiero with the aero package on it? Those can fetch pretty good money still, even though it is a notchback. I bought a 85 GT a year ago, fixed it up and got $5k for it. Seems like there ought to be some crappers out there for cheap. Good luck on your build, we will all be following your posts. I have hardcopy of your first build on the internet some 8 years ago now, but this one ought to be a beauty. Eric

                Eric,
                This one is not really worth fixing. The engine is dead and who knows what else it needs. I am going too offer the panels on the PFF forum and here.... The panels themself are in "okay" condition. Funny that you kept a hardopy of the old build. I dont even have a copy of that. Care to copy a set for me? I will pay you for your trouble.

                        Re: My AD355 Spider - Now a coupe build

                        I have decided to convert it over to a coupe from a spider. The turning point was the difficulty in creating a top that is fully functional and looked good as well.

                        some updates: I loosely fit the drivers door, drivers and passenger fender and tried to align the front bumper. I now have several questions... most of which I am sure john told me how fix but that was years ago and now I don't remember (a sign of old age)...

                        With the door installed all the way toward the rear of the car, I can open the door almost all the way but not fully. Is this normal?

                        The Fender was installed using the holes drilled in by John at AD, the gap between the fender and the door does not align rather well. I know I can elongate the holes to align the fender better but before I do that, am I missing something with the door or fender?

                        I have everything loosely fitting right now and used the front valance piece to set the distance between the front fenders. The bumper seems to be larger then this distance....

                        Also john supplied these two pieces bolted to the front fender. I suppose these are somehow attached to the front bumper...

                          Hey Spider, congrads on the start up of your AD build. I think the problem with the alignment of your door is with the small piece of metal on the front door edge a few inches below the top bolt, that has to be removed. The AD door skin has a little dimple in it where that metal piece hits it. I had the same problem aliging my doors and a call to John was the fix for me.
                          Best of luck, David

                            figured out the issues with the door. The drip rail needs to be trimed so the door can open all the way and I forgot to remove a small piece of plastic on the door shell. Now I can align the fender. It is amazing what 5 minutes on the phone with John can do. He also told me how to install the bumper. Watch for more pictures soon.

                            Let's consider this installer error. You just can't find good help anymore..

                            David....that was exact what john said too!!! Thanks for your help. How is your build coming along?

                              Every once in a while, I will get this "John does not know what he is talking about, I am doing to do <project> my own way." and it gets me every time. I just gave up and did what ever John recommended.
