    Hey guys , i m new here

    Hey, i hope i found the right guys to give me some help,
    the project is not realy a kitcar in the standart way to do it but let me explain.
    The plan is to build the body of a VW Golf Mk2 on the frame and the technic of a corvette C4 , this means i need a selfsupporting frame where the body can be "bolted" on, the idea behind is to have a strong V8 with it s suspension etc. under the enlarged body of this Golf, why i wanna do this?
    Just for the fun, to see the faces of some high power sportcar drivers with tears in there eyes
    So can anybody help me out an tell me more about the c4 chassis, i found out that the chassis type changed in 1992... Does maybe anybody has pictures of a stripped down frame of a c4 to give me more ideas i could build this up? As far i saw on the internet the c4 is a pretty common base for cobra kitcars, but nobody shows pics about it.
    Thanks in advance

    Few months ago someone here on the forum had a Fiero-based tubular chassis for sale. It was some kind of custom Fiero chassis for the track with Fiero roof panel, NOT modified standard Fiero chassis. I think it's still for sale but can't remember who is the owner of the chassis. Maybe it will fit according your requirements, but not sure what's the wheelbase. Probably it can be stretched.

    Re: Hey guys , i m new here

    Thanks but thats a little bit my problem, cause i m living in europe i need an original car imatriculated allready here, otherwise the newer tighter laws are applicable and it is impossible to get immatriculated again, therefore the best is to have an original car and do the stripdown and mods myself with documentation (fotos videos) to proof to the local auth. that all work have been done i.a.w. regulations, therefore the easiest ist to have a selfsupporting frame ( so i can proof that the construction is safe) and "only decorate" it with a golf bodywork
    Thanks anyhow.
    Anybody else knows the c4 1992-end chassis ?

    Re: Hey guys , i m new here

    Welcome, and I wish I could help with pics but I can't seem to find any. The C-4 ran from 84-96. The frame as we know it was not a simple structure. It consisted of a typical metal frame with a "tub" bonded into it at the GM factory. These 2 components together are what is referred to as the frame of a C-4. If you were to strip out the SMC tub you probably wouldn't have much left. [Non-self supporting] Wish I had a pic..... I'll keep looking

    Re: Hey guys , i m new here

    Thanks for your help Daleford, so as i understand you you do not think that the c4 chassis is the ideal base for my project, what i dont understand is that when your looking on corvette pages they talk about a Unibody with partial front frame up to 1991 and starting in 1992 tey talk about a Fiberglass; separate ladder frame with cross-members chassis.......
    I found a pic of a 1984 vette and that looks the same as you described it to me but unfortunately i dont find any pics about newer models

    Or do mybe know an other good base "selfsupporting with v8 pontiac chevrolet etc. to do my project)
    Anyhow i dont know if this type of mod interssts you but in case of let me know and i will keep you informed about progress
    Thanks and BRGDS

    Re: Hey guys , i m new here

    Humm..... Maybe I stuck my head in where I shouldn't have. I am not an authority on this. From your pic I don't see why you couldn't use the C4 frame without the bonded fiberglass tub.
    Also I don't see why there could be much difference from 92 on. The bodies are the same so I assumed the frame would be the same. Sorry, guess I am not of much help.

    @Daleford: Thanks for your help anyhow
    The problem on the chassis type shown on the pic that in that case the window frame and the rollover frame would have to come of to get the golf body on but in that case the strength of the frame wouldnt be the same anymore, in case of for example the c3 chassis (ladder frame) i wouldn t have to pay attention to this sort of problems, i simply could bold the body on it.
    The problem why i wan t take a c3 vette is that they are more difficult to get here in europe and in case you find one they are more expensive than a c4 and the technic (suspension brakes etc is way behind the c4)
    So either get a late c4 (in case thats realy a different chassis) or find another sportscar (chevrolet pontiac ....) with a ladder frame chassis, anybody has an idea what i could use............

    You are certainly right on the C4 suspension and brakes being far advanced compared to the C3.
    Good luck with your project.

    Another option for you would be to use a 1986 - 91 Corvette Convertible Frame.

    Essentially, they are very similar to the 84 frame pictured above except without the "built in Roll Bar / rollover frame". GM made some changes to the lower structure on the rag-top cars as well as eliminating the roll bar portion (obviously) , and I believe incorporated a "lateral type" of brace in the area behind the seats as well as additional support on the bottom of the frame.

    I too am not an expert on the C-4 frames but I have seen quite a few bare frames both Targa-Roof cars and ragtops. I think the ragtop frame may just work for you.

    By the way, you can try the links below for some additional info. There are companies (not sure about UK shipping though) who make C-1, C2 and C-3 Frames with mounting points for C-4 front and rear suspension. It's a great way to upgrade the suspension and braking of the older frames / cars:

    http://www.colliertechnologies.com/products.html

    You can also see some pretty cool round tube upgrade frame info here as well as a chassis design that incorporates a C5 Front / C4 Rear (which I think is a fantastic idea):

    http://www.sriiimotorsports.com/196382corvette.html

    I am still toying around with the idea of a "C1 / C2 on a C4 Chassis Project. There are companies the reproduce the C2 bodies for use on the C4 and C5 Chassis. I kind of like the retro look of the project, especially the convertibles. I think the updated chassis examples in the links above would even make for a nice C3 body with C4/C5 Chassis and running gear. (It's about time someone put a little interest back in the pretty much overlooked C3's. Not a bad body in my opinion but Powertrain and chassis were a real bore during that time period.

    Re: Hey guys , i m new here

    Hey Kit4me, thanks alot for your help, the idea with the convertible frame is realy good, and you think to cut the window frame away is not problem?
    i would tend to go for a c4 an not for c3, it s much easier to get, much cheaper and the technik is already top without swapping c4 components to c3 chassis.
    Does anybody has more measurements about the c4, not only lenght, wide height , but some kind of drawing with all kind of different measurements, like this it would be much easier for me to se how much i would have to change the golf body to make it fit.
    Tomorow i will call up the specialist of the local auth. to see if they might accept my project to let me drive in public traffic,
    I hope so, the european laws getting stricter and stricter
    Thanks an brgds
