Carbon fiber lifetime?

& putting heavier cf hood is?

You wawnt front? K, here you go.
Battery - 29.6 lbs (PC680 battery weight less than 15 lbs).

I didn't say anything about a hood helping. If anything, I said it's not worth the money.

Carbon fiber wrap

Cheaper
Easier
Lighter
Reversible

But it's not a legit original so you will get hate online. O wait you will get hate online unless you buy a 2k custom dry carbon piece. O wait you will get hate for that because you spent 2k for a minimal weight savings on a "25k car".

Do what you want for whatever reason you want. There is always going to be people who don't agree with your decision and others who love it. What matters is if you love the look, function, or both.

Losing weight is going to help more than the change in balance hurts. Every time.

i have the Seibon hood and love it. I wax it pretty much 3-4 times a week just to keep it fresh but will be taking it back to get re-cleared in about 8-9 months. It comes cleared already but i would like def a thicker coat and most clear coats now in days have UV Protection in them blended already.....

It depends on what you're doing. But yes, there are advantages... slightly quicker acceleration, slightly better fuel economy, etc. But all of the advantages (and disadvantages) will be relatively small overall. So your experience likely won't be changed drastically with these kinds of changes. But if you lose weight in the right area (like when some people lighten up the load up front with a smaller battery), then that will help in multiple ways.

Do you know how much it costs to re-clear carbon fiber? I was thinking about doing that to my Evo's carbon fiber trunk at some point.

Definitely. And I'm not a good enough driver to see any benefit from anything other than massive weight savings. IMO, if you truly want to save weight you remove things rather than replacing other things with CF.

I finally did the one thing I always joked that people should really do if they want a lighter car.. added the light weight driver. Go to the gym, people.

Yup. Unless you're going to the track, most carbon fiber "upgrades" are for looks anyway and as you said won't really benefit the driver in a noticeable way. Back in 2000, I put a carbon fiber hood on my Honda. Zero changes, but I at least did that since my stock hood was damaged and needed to be replaced. I got a carbon fiber trunk on my Evo last year, but again, it's because there was some damage to the stock part, so I figured why not.

I agree. I can't believe how overweight some people are who drive quick cars but talk about how they want their car to be as light as possible, and they're stripping interior parts out and going with carbon fiber hood, doors, trunk, etc.

Shouldn't cost much more if at all more than getting an equivalent steel panel painted. The prep work should be nearly identical. If your hood has big vents/details that are more complicated to prep that's another story.

I wish car panel manufacturers would do just a *little* research into the resin systems they use on their hoods. You can get epoxies that are very UV resistant (Most cycloaliphatics are a good place to start), and with a UV clear they will almost never yellow. Instead they go with cheap epoxy and try to protect it with a clear coat. If the top layer of epoxy fails under the clear the clear is just going to flake off even if it's still perfectly fine itself.

On the commonplace end of things, epoxy based surfboards are a good example of a product that spends a ton of time in the sun and has to be designed to do it without a clearcoat in many cases. On the high end, the bare carbon finished Pagani's, Koenigseggs, and even the roofs on some M3's etc. are all bare carbon. Do you think that they want to have customers bringing them back after a year with yellowed and flaking body panels? I think not. There are proper materials that eliminate the issue. Most companies just don't want to dish out the $$$ needed for them.

^ But the clearcoats they use on bare OEM carbon fiber, especially on higher end cars like those, are FAR better. The clearcoat on my Evo's stock carbon fiber wing held up pretty well for being a thin coat. But the clearcoats on the more expensive stuff is pretty solid. I remember reading something about the clearcoat used on the Corvette ZR1's carbon fiber roof costing $60,000 PER GALLON (and I just looked it up), so that is probably made to last. Having seen a ZR1 on Monday and touched the roof, it did feel like quality work made to last. And that also explains why going with a Veyron but just keeping a clearcoat rather than selecting a color adds a couple hundred grand.

Just as a note, the UV blocking additive is $60k per gallon, but likely is mixed in at a very small percentage. The clear itself is closer to $2k per gallon.

Of course, I know they're not using the entire gallon on each roof and that it gets mixed with other liquids. But I'm pretty sure that that good stuff isn't used on most other aftermarket carbon fiber products for this demographic of cars.

I'd be curious to know what the additive is. My guess would be some sort of nano-scale ceramic filler that either completely absorbs or completely reflects UV so that it never gets to the epoxy. Something like what they put in the 3M Crystalline tint films.
