I've been doing some experimenting. Been checking out the FC doors. I'll try to estimate how much work is involved and come up with a minimum number to get this going.
Heck. I might even try one door first :). Ken |
I believe the FC doors are very easy to seperate the exterior skin and seperate it from the support/inside of the door.
Will we be able to use all the stock hardware (windows, regulator,locks,rods,handles,door panels)? |
I have to analyze it and see how each one mounts and how much time it takes to clean off all the goo :)

Some of my fellow engineering students at SDSU learned this the hard way, when their vacuumed/post cured unicarbon sandwich layup could absorb less energy than the same part made from an equal weight of fiberglass. --Alex |
i like the porsche race-style interior simplification

I think one thing to consider is that the FRP door would actually be stronger per weight in a crash than the carbon. Carbon is very strong for its weight, but its high stiffness means that it can't absorb as much crash energy as fiberglass or kevlar.

I'm interested in the vacuumed FRP doors for the FD for $700-$850. I might go for vacuumed FRP hatch too depending on price and finances.

What are the weights for a stock FD door and a stock FC door? I know they are both very heavy. They feel close to 100 lbs each.

As for strength, I don't think it matters too much if your in auto-x, but for something where you have a chance of someone hitting you on the track then it would be nice for it to have some strength to it. I am interested in these, FRP is a definite! If these things get wrecked I don't want to have to pay an ass load to get some replacements! When do you plan on having these done? and how long would they be available for? I may not be able to buy them as soon as they come out, or I may have to wait on that sunroof.... :scratch: |
Any chance of carbon kevlar? Hit me up on a deposit when your getting these
rolling Ken, I'd be in for a CF/CK FC set. |
I'm in. Let us know.
|
Sweet, thats awsome. Maybe in about 3-6 months I could grab a pair.

S5 doors
I believe it's about 65-70lbs. With everything (mirror-glass-window regulator handles-ect) I can curl it in one arm. S4 doors do not have the extra support the s5 did they should be about 10-15lbs lighter than s5 doors. I have a couple of doors sitting in my attic if im not too lazy I will pull one out and weigh it. Also for ken just use DRY ICE to freeze the goo and use wooden chopsticks to scrape it off or a painters mixing stick, to help avoid scratching the steel. You can also use a bottle of compressed Co2 and spray the goo with it to freeze.then scrape. The remaining residue can be cleaned off with paint thinner or acetone. Should take no more than 15 minutes to clean. |

OK since people were asking i took my 90 GXL door with window regulators removed, glass removed, and window trim removed.
All that stuff should add up to just under 10 lbs but here is the weight of the door without the few items. lighter than i thought guess i'm loosing muscles! It says 50lbs for a S5 door without glass and window regulator. https://www.rx7club.com/attachment.p...2&d=1222280330 https://www.rx7club.com/attachment.p...3&d=1222280330 |
Damn! so i was basically right on the weight.... I thought I might be about 5-10 lbs. off.
|
it is an old scale but weighs me only 5 lbs over at 225.
My digital scale says I am 223.2 so I don't think it's too off. Remember the door is missing the door panel, power window motors, no glass. I can say that might be about 10-15 lbs more so most GXL S5 doors should weigh about 65 lbs (give or take 5lbs). I had a set of fiberglass doors for a FB and those weighed in at 19.8 lbs each without all the guts. They were stiff not floppy parts. The difference between power and non power was about 8-14 lbs only. S4 doors are lighter than comprable S5 doors.I used to own a 86 sport model with no sunroof before and were noticably lighter than 90GTUs doors by about 15-25 lbs I believe maybe im smoking something but please correct me if I am wrong. BTW I would like Carbon Fiber and a set of Fiberglass doors so let us know when your ready to make them. If you could I would also be interested in a set of CF or FG outter skins. I am sure most people wouldn't mind keeping the inner frame and having a CF or FG skin. If they know how to install just skins. If not I can put up a DYI on just the outer skin install in the future if you do happen to sell some . They would drop some weight but not all of it and the idea of being slightly lighter is fun. I am sure it would be much cheaper also in the 200-350 range?? Also I like the idea of dry carbon with higher strength. Using good super clear epoxy, honecomb, vacuumm infused! I love it. I wish I had an autoclave at home but I do have access to one that can fit a whole fc near by.I just dont have time to make CF parts for production but wait a few years and everyone will see my widebody GTUs soon enough(alot of carbon goodies) I have a method of getting more gloss out of them with a special film type material sorta like clear sticker bra. |
you guys saying you want cf, think about it. If/when those things get destroyed on the track, do you really want to pay the price for another? or a couple hundred cheaper of the FRP? Just something to think about.

Don't cry I'm Broke on the forums. If your afraid to crash on the track then you don't belong there with CF doors or even at all. |

So....if the door weight revolves around durability, and quality fiberglass is more durable for a given weight, couldn't you build a fiberglass door lighter? And if a fiberglass door is lighter, why pay more for carbon? Its simply not the right material for the job, IMO. Kevlar in the right places wouldn't hurt, though. |
I'm wanting CF. The car that will get CF doors will be my show car.
|
I believe strength and stiffness comes with what type of weave you are using and how you lay it down.Also the type of Epoxy Resins that are used and last the method of production(vacuumm infused in a clave or wet lay or just bagged).If the CF doors are made in an AUTOCLAVE there is almost no way a FG door will be lighter and stronger. " No way"? Well atleast thats what I believe.
I know u can lay up 1/4" of fiberglass and 1/4" of CF/Kevlar composite will stop a medium Cal. bullet, Fiberglass wont. Almost all race cars use CF composites . Carbon Fiber is 10 Times stronger and nicer than Fiberglass! Fiberglass is not stronger than CF pound for pound NO WAY BUDDY. The only thing better is it's cheaper. |

Everyone should read this thread if they haven't...
https://www.rx7club.com/interior-exterior-audio-26/rx-7-series-6-carbon-fibre-doors-483641/ It talks about... FD dry carbon fiber door = 10 kg or 22 lbs weight savings/door. Carbon fiber doors having flex and molded anti-intrusion bar for safety. Carbon fiber damage repairs that are barely noticeable. and much more IMHO... The CF doors probably could be made safer than FRP doors because of the strength if the CF is flexible enough. Some CF can be repaired more easily than most people think if perfection of the looks is not necessary. I don't know that these are reasons enough to justify the higher costs over FRP where the weight difference might be 2 lbs/door? I would expect the doors could be made safe enough in either material and probably as safe as the stock doors. The anti-intrusion bar commonly comes unwelded on the FD steel doors from vibration (door makes a hollow tinny thunk when closed). I bet that wouldn't happen with a molded anti-intrusion bar. |
Any more flaming and there are going to be repercussions...
Keep the bullshit down. This is a warning. Ken, feel free to clean up your thread here if necessary. |
hey blackball7 maybe you should drive a 240sx.

That doesn't sound like fun at all! |
Very tempting price if you can get them in the $1100-1400 range for the FD. How hard will these be to install? I've had the interior door panels off my FD before and it looks like it would be hard to replace the door shell.
|
I noticed this site has FD full doors in carbon fiber and plastic for a reasonable price...
http://www.aerokits.net/cart/index.p...x&cPath=75_204 I hear that GTP parts are cheaply made and don't fit well but the C-Wings parts I've heard about fit better. The CF C-Wings doors look like they are CF over fiberglass but don't look too bad. I wouldn't want to take the chance on something that doesn't fit well and I would like to have vacuum infused for weight savings and strength. Anyone have any experience with C-Wings parts? Any opinions? |
No 1st gen C/F door talk? :(
|
any update? is this gonna happen and when would a deposit be needed?
|
Im In On The Cf For Fc!!

The site you are referring to is basically selling C-wings products. They are all handlaid parts. Ken |

pre monday bump.
update please! |
Count me in for a FC set
|
Might as well make a set for the 1st gen. Please!
They would go well with my CF wing, splitter, and canards |

^i have cash waiting for these to be made.
|
I do too, if it would speed the production at all, I could pay %100 now with the shipping cost.
pretty much i'm a motivated buyer, since these are the last part I've been wanting to get before the bodyshop sendoff. got the widebody, hood, diffuser, bumpers, and a spoiler this is all I need now. hehe |
bump! (no, Im not anxious or anything...;)
|
Just read the "other thread" Props to Carbon man, but I think we're more realistic and pricing and can offer something fairly adequate.

I think it is great that you're bringing dry carbon up to the stage. Dry carbon is far more superior to wet carbon. I'm interested in the doors, but it all depends on how it would look from the inside. Will the door panels be able to fit right on and will those of us who drive our rx7s on the street be able to use our power or manual windows? In +1 set if the above is true. |

WOW!!! Ken want me to drop off some doors too??? lol
|
ACtually.. yeah.. if you could :) But not yet... Im doing some experiments on something else right now.
|
Just hit me up later when you need them...How are the roof skins coming?
