View Full Version : Composite Materials Height increase with CF?


Calcium12-21-2009, 11:53 PMI like the look of carbon fiber and I'm not really interested in any weight loss. Because a proper cf hood is really pricey I'm planning on covering my hood with cf cloth to gain the look. I was talking with someone about it and he brought up that, if I go over the normal hood, the cloth and resin will raise the surface 1/4in which might not lay flush with the quarter panels. Approx. how much will it raise the surface of the hood, also by hood i mean frunk. (I think, I'm not too good with mr2 terminology just yet) mattdouken12-22-2009, 12:19 AMIf you have this posted right you are wanting to lay a carbon fiber sheet over the existing hood and leaving them both on. And to this I say

"How about instead of ruining your car an being a fanboy,fast and furious driver.... you think about how valuable and rare a MR2 is and not deface the value of it. I'm sure even honda guys will laugh at you"

And if I'm wrong and you are wanting to make your own CF hood. Then good luck. David12-22-2009, 01:00 AMOh gawd. I don't mean to flame, but if you like Carbon fiber for the look, you have the wrong car and/or are on the wrong forum. Honda tech is that way on the interwebz. ----> mattdouken12-22-2009, 02:30 AMOh gawd.

ROTFFLMFAO....:rofl::rofl: turboguy12-22-2009, 12:23 PMNow to seriously answer your question...

It will add some thickness to the hood, but it's barely noticeable. The added thickness will be more like 1/16 to 1/8 of an inch. This won't be noticeable at all. Your friends have no idea what they are talking about.

The second thing, laminating a hood with cf compared to a new cf hood, the new cf hood would be cheaper. To laminate the hood, it would have to be repainted flat black and then sealed. This is so no color shows through the weave of the carbon. Add to that two layers of cf cloth and resin and your looking at close to $600. Last I saw, ebay cf hoods were going for like $350 to $400. mmarookiejoe12-22-2009, 12:31 PMAside from this not being my idea of cool, to each their own. That being said, Turboguy is right. You may save A LITTLE money doing it yourself, but you aren't as likely to have as nice a finished product (no offense, I just based that assumption on the information you cited in your orignal question - for all I know you may be a fabricating genius), and you will have spent a lot of time and effort - how much is your time worth in relation to the meager financial savings, (if any)?

Don't do it!!! brianbooth12-22-2009, 12:36 PMCF is a lot of money for not much weight loss. Calcium12-22-2009, 12:42 PMI never thought about having to paint the hood to keep colors from shining through. Maybe I'll just buy an ebay one. David12-22-2009, 02:53 PMI'm thinking the ebay one is going to have bad fitment. If you want to modify your car, you have to be willing to pay good money to not get junk. Please update when/if you get the ebay hood. mmarookiejoe12-22-2009, 02:57 PMMaybe I'll just buy an ebay one.

Depends on what brand - you can get good stuff on ebay too...

I had a VIS Racing carbon fiber hood (came on a 93 Prelude I bought , fixed, and sold), and the fitment was perfect. mattdouken12-22-2009, 02:57 PMCF is a lot of money for not much weight loss.


Says the guy who weighs things by hand....


The stock hood has good weight to it, as for the fiberglass engine lid and trunk lid without a wing are pretty light.

But replacing the hood with a CF one is a good bit of loss. Definitely worth the money. David12-22-2009, 03:03 PMVIS is a very good brand. They're usually around $500 for a new hood. I've never really looked for them on Ebay though. And yes, the savings from a CF hood is a huge number. Try picking up a stock hood with one finger. ;) Calcium12-22-2009, 03:06 PMWe'll like I said, I'm not too interested in the weight loss. I bought the car for cheap because it has some serious rust and one of the cylinders was mis-firing. My purpose was to practice repainting and play around with fiberglass/bondo. I thought it would be fun, albeit a bit expensive, to try to cf over something. I didn't think about some of the surface prep (such as painting) that I would have to do, so I'm not sure if I'll do any of it. Either way, thanks for the input, even the flames. =) David12-22-2009, 03:18 PMLol, no flames. Just us trying to keep you from doing something stupid, or something you'll regret. Take care of the bad cylinder first, then take care of the rust, then paint, then worry about doing little things you'll like. If you don't mind me asking, how old are you? Calcium12-22-2009, 03:22 PMThe cylinder is fine now, the car had been sitting for two years and the spark plug had fallen apart, replacing that and the vc gasket stopped an oil leaking problem so the engine is running as good as can be expected

18, in college, so I have lots of time and not alot of money. David12-22-2009, 03:30 PMI have even more time and less money. I still refrain from doing possibly ricey things to my car. You should just stop unnecesarily spending money, and save until you have enough to buy a good air compressor and tools. It'll save you a lot of time. Once you have that, search a little on good techniques of rust repair. Then have at it. Calcium12-22-2009, 03:34 PMI hear ya, I'm not a fan of fart pipes or short rams, I just like the way cf looks. I wanted it as a spring project painting the car using this method, Home (http://rollyourcar.com/default.aspx) Madlife12-22-2009, 04:44 PMThe stock hood has good weight to it, as for the fiberglass engine lid and trunk lid without a wing are pretty light.

Fiberglass engine lid? never knew there was one..

Side note.
Aluminum WRX hood vs MR2 CF hood = not a whole lot
Metal 94 celica hood vs MR2 CF hood = Pretty damn good difference. Ive hit the prop rod and had the CF hood come down on me. That was not fun.. The celica hood would probably knock me out..

Another side note...
My buddy who thought his mustang was the greatest car ever got a CF hood for it. He got mad at me because I said he wasted money because he has an aluminum hood. 4 months later when his new hood finally showed up, he was very dissapointed.. It was maybe 10lbs lighter...:rofl:

Sorry off-topic.. If you like the CF look go for it.. but beware, a lot of the cheaper CF hoods/trunks are like cheaper/replica body kit parts. fitment is sketchy. mmarookiejoe12-22-2009, 04:53 PMWhatever you do, DO NOT buy from Ground Dynamics!!! Dirty bastards randomxzero12-22-2009, 05:59 PMDont roller paint your car man haha i did it its a lot of work i mean a lot a lot of work.. and in the end it looked okay..

i liked the original red better than the rust o leums 328FTW12-22-2009, 06:01 PMI hear ya, I'm not a fan of fart pipes or short rams, I just like the way cf looks. I wanted it as a spring project painting the car using this method, Home (http://rollyourcar.com/default.aspx)

Check out some of the painting threads round here as well like DR Darkmatters and mine. There is heaps you can learn about painting, it's one of the most frustrating things sometimes but the payoff is great when done right.

On a slightly related note the most awesome hood/front for the mr2 is a full fibreglass liftoff one they are so awesome. Pull pins then lift off or tilt forward it just looks evil. Then again my racing roots may have something to do with liking that and gt40 fronts.

Yeah the "Milano Red" on those civics is one of my favorite car colors, I've seen it done with marine deck paint and it has turned out really well, also what type of clearcoat did you use? randomxzero12-22-2009, 10:58 PMi got it off the hondatech forums its rustoleum oil based paint you dont really need a clearcoat what you have to do is wet sand it until the orange peel is gone then wax it and i guess thats your crappy clear coat lol.. i would do it again but i rather just learn to spray it will be much easier.. the prep work is practically the same, just take a paint class at a community college and they'll let you use all their tools and paint booth to get your car done..
