It sucks to have to bring people back down to Earth sometimes. No matter how nice you are about it, you're still considered a jerk.

make a widebody concept out of fiber glass, and then buy a ton of carbon fiber vynal

and sticker it up. thats what you should do

you are adding weight to a car via body kit, and making it with light weight material

dumbest thing I've read/seen since the guy who layered up his FD with CF sheets OVER the bodykit!!!


You can't really REDUCE weight when you ADD extra layers. No matter how lightweight the material is, you're still ADDING weight.

If you were being sarcastic then: otherwise

Actually it can't. Its nearly a physical impossibilty with all of the extras you're talking about unless you're going to make something that requires building a tube chassis and gutting any exterior sheet metal. You can only add to the quarters, add to the doors (unless the are full, two piece, bolt on doors which you'd best make in an autoclave since they're replacing strucual members), add to the rear end. So unless you're hood and fenders take more weight off the car then the entire rest of the body kit, the car WILL be heavier afterwards.



Anything is possible. But before making such a bold claim, you best windtunnel test both a stock bodied and "your" bodied FC. Thats money.



Whoa whoa whoa. You don't even have a design and you are tossing out prices??? Do you even have a REMOTE idea how much labour would be involved in creating something like what you've proposed and have it be even close to decent quality? We're talking hundreds of hours and thousands of dollars in material making moulds.



Respectible act of charity, but there's no way (in reality) you'd give away your designs for penny's on the dollar (which you'd have spent thousands of) after months (realistically year{s}) of hard labour.



..........






Well? lol
the idea is that the entire front end would be replaced, so not a single stock panel there
the doors would in fact be new
and yes, the rear quarter panels would be extra, but hey, i bet the wieght savings among the rest of the car is more than that, and on my personal car, i plan on making a tubular chassis.

Front fenders aren't heavy. Last I checked they're approx. 3lbs. Hood (if its steel, so best case scenario) would save ~40lbs. Bumper cover is approx. 4lbs. If you're deleting the pop ups, theres approx. 20lbs total.

So effectively, the best case scenario is that this bodykit may save 70lbs, off the front before adding any other parts and lessening that number. And thats an absolute best case. This is presuming you have no extra bracketry or hardware added to your CF parts to allow them to attach to the car.

OK, in all honesty. How much experience do you have working with fiberglass and carbon? What have you made out of either of these materials and how did you make it? Because the complexity and moulding required to make a strong door is not something you can really do in your backyard. For a part like that, which will require alot of strength (not to mention some steel beams. A CF door would never come close to survivng a direct impact from another car like it should) you are near the territory of requiring to cure it in an autoclave.

A car with fiberglass or carbon fiber aftermarket doors is going to be a DEATH TRAP! The stock doors have the door beams in them that protect you not only from side collisions, but significantly add to the front and rear end impact protection by giving the forces a conduit around the passenger compartment, keeping it more in tact then it would be otherwise.

The ONLY way I'd ever consider something like that is in a full on race car with some fairly substantial door bars to compensate.

$4500 for a nose panel, hood, front fenders, doors, side skirts, rear fenders, rear bumper and hatch?! No F'n way. That won't cover the labour costs, nevermind the materials, tooling and so on.

i have made many interior parts from FG, and helped make a dashbored out of carbon fiber

i would use the dry CF process
this is where the resin is pre-impregnated in the material, and then it is baked in an oven.

yes, there would be a frame, most likely stainless stell within the door to hold it together
and i bet it holds up better than stock.

ok
but whats gunna happen when i win?
you're very much correct saying this might take me a while, but hey, i have time.

Door panels and a dash aren't impressive. What have you moulded and how many opposing face (3D) edges were there? Making parts like these will require tooling 2, 3, possibly 4 or 5 piece moulds for each part. This is an entirely different ball game.


By the fact that you mention an oven, I'm going out on a limb and guessing that you actually have an oven capable of holding parts and their respective moulds of this size? Is that a yes?

So, more tooling and material costs.

Actually I can answer that pretty easily. No it won't. Carbon fiber is "stronger" then metal in many ways. But in the application of a door with respect to a collision or accident, CF would simply shatter and break, where as steel bends and absorbs. You're efftively eliminating a cruical crumple zone of the car.

lol K, weigh the car now. Post a pic. When you're done if the car has lost MORE then 30lbs (no empty gas tank trickery!!) I'll paypal you $20. No shitting. Hell, I'll even make it $20CDN since by the time you finish it, that'll be $100US.

i am aware of the complexity of the molds. I have never made multiple section molds before, but hey, it can be done, so i'll do it. (and i can use that argument for everything)

oven, no i do not, but i'm sure i can find somebody that has one i can use
just find some pottery shop..

if thats so, then does that mean that all these supercars out here with there carbon fiber construction aren't that safe???
i'd figure they are..

awesome! i can buy a celebration quarter with that!

Trust me. If you've never made them before, you'll never make them on a large complex part. There's far too steep a learning curve, and when you spend a month and several hundred dollars prepping a part to make one, and screw it up, you'll be that much more discouraged.

Wait......a POTTERY shop with oven large enough to bake vaccum-bagged (at least I'm hoping. If you're going pre-preg you'll want some form of resin control) mutli-section moulded parts??? This is not something you find at a pottery shop and borrow for an afternoon. An oven used for this type of thing is very precise, and VERY large.

You're mincing words here...well, just taking it out of context. You do not have the resources that Ferrari has. You cannot produce vehicles and provide VIN's to the government and do crash testing. Any car that's made of carbon fibre and has complete CF doors *has* beams in them, plain and simple. Sure, you can make your SS skeleton, but the point is - do you KNOW it will work the day someone T bones you at an intersection? Thats alot to lay on the line in the name of attempting to shave some weight.

many supercars dont have a beam of steel in those doors
they're straight CF
and you cant just say its about resources
its about EFFORT, and determination
i have that
and no jacked up mold is gunna discourage me, its going to boost my NEED to make it happen.
that along with some spare money

who else wants to bet 20 bucks!?!?!?!?!

That is the dumbest thing anyone can say. You are comparing a design that you plan to whip up in a pottery oven to a super car that will have been designed by engineers, crash tested, approved oh and they get made in an autoclave

I think that you would have a better chance buying the veilside kit and making it fit a fc, and not even think about making another one. Fc owners are poor for the most part and probably would never even think about dropping that much cash for a body kit, and you would have the only one in the world.

I don't know about the POOR part. The reality is:

Most FC owners are young. Young = going to school = limited budget = not gonna blow any money on stupid ****. Just keep the car in good running shape.

The minority of FC owners that are not young are more likely to have a larger spendable car budget but they tend to be more RACE oriented. HP first, looks last.

then there are the elite few that own FCs, have modified whatever it is that they wanted and are looking for things to waste money on.

Poor isn't the first thing that comes to mind. I'd go with CHEAP.

Sounds about right....being thrifty helps a lot! I may not be poor, but damn if I don't want to go out and buy a $2500 body kit. But, props to you for doing what you want, I guess!

for those of you who are optimistic
i made some light sketches of what i have in mind






and yes, i suppose i would use an autoclave.. do i have one?? no
could i possibly use one, i believe i could make that happen..

No actually I don't believe you do. See, if you really did have the salt (and money) to do this, the thread would be titled "group buy ______" or "widebody FC pics" and you'd have of some pictures of the finished product. Or at the very least, a project underway looking for ideas on what to add or remove. You have a thread asking if anyone would buy it.

Yes this I understand, but you still really have no idea how much work and money this will take. Have you ever done any regular body work even?

Which is another good question. How much do you actually think you'll spend - don't include any money for your time - on this project for materials before you're able to ACTUALLY produce the first piece of the kit.

I hate to say this CHAOTIC FC

but we here on the rx7club like to see progress or even an atemp, most guys here sit around all day just looking to see what are they doing next on their cars
not what are they dreaming of doing

you said you paid 900 for the car right well lets start off by fixing all your problems first- the harsh comment of the fellow members wasnt harsh at all in my opinion

that turbo running on stock ecu on stock injectors is a NO NO that needs to be fixed asap

no even if you get a standalone your fuel system will need some massive work to play with that size turbo- what is that a diesel turbo off a mack truck

going to the engine invest in a rebuild kit first and second a set of s4 t2 irons- I DO PORTING

it would hurt to change them housings too they look beat up, then after you have that motor built and running it would be a good start to begin your widebody project

as for CARBON FIBER you know theres a shortage in the material itself right and a standard weave of 5ft by 50 runs a couple hundred bucks

for a job as kits,bumpers..etc these parts are best if they are vacuumed and cured , handlaying it will end up just like plain fiberglass ,streaked and not strong

i hope you use the search feature and find more info on more important things like getting your car running and maintaining it, looking up to hopes and dreams will only keep you there you have to bust your *** working and getting your hands dirty to get somewhere in this line of cars

oh a friendly tip from me save your money too because you dont want to have your hopes up when you blow your engine and cant rebuild it because you spent $654376546587657 in a widebody cf/fg/bondo kit

its a very finely controlled pressure cooking oven which controls pressure/vacuum AND temperature constantly

no i did NOT dickapedia that

I'm not an artist so I honestly can't talk **** about your drawings. All I can say is: keep working on it and try to improve the design so it's visually appealing.



Edit: also, stop talking about it and do it already.

you just basically told me how to do a plan that i already had
i am aware of the state of my engine
i am saving money to get myself microtech, along with much bigger injectors, good clutch, blah blah
thats a whole different thread
and i already know porting (its on my rebuild page)
and i happen to like my 6 port irons, more port area

ok fine
the mclaren f1 is known to have literally had every single chassis and body panel component made of carbon fiber
now instead of contradicting me

he's not contradicting you as much as he's TELLING YOU: FERRARI SPENT HUNDREDS OF THOUSANDS OF DOLLARS TO MAKE THAT 1 MILLION DOLLAR CAR.


Comparing the R&D that ferrari did to what you have laid out for us is not logical.

3 days of brainstorming(hell!! even 6 months to a year of brainstorming isn't enough), 2 days of drawing, no $ invested towards research/development/parts/tools/shall I continue?

You might be upset at all the negativity but the only tip I can give you is:

Listen to the negativity and IMPROVE YOUR IDEAS and EXECUTION otherwise this is another one of the many "CF______" thread.
