For being a car "community", I'm always surprised at how much of Jalopnik is made up of posters who have no car knowledge whatsoever. Looking at you, "Fiberglass springs I think I'll pass" guy...
Maybe I should have been more specific in my comment. The amount of _criticism_ that gets slung around here by people who just don't know about WTF they're talking... surprises me.
@go_racing84:
Ah, I get you. I think that sometimes they think they're being funny, but end up looking stupid. Some people don't know how to express their opinions in a diplomatic way. I expressed my opinion in a stupid manner once and had lots of guys jumping down my throat. I think a bit longer before I write now. (Well, not always). ;)

@P161911's comments will be lost on the 2nd page: "Only in the past 10-15 years have composite materials been used more extensively in production vehicles (and often only expensive sportscars)." Is a little bit of a stretch, no?

@BaconSandwich just found out how to change his...: Corvettes have had transverse fiberglass leaf springs for years. They're easy to package, light weight and can be tuned for variable spring rates very easily. I'd more likely say "Heavy old steel springs that take up tons of room and increase unsprung weight? Hmm, I think I'll pass"

My dad had a lady friend at one time that had bought a 1953 Corvette brand new and she had the car until she passed away in the mid nineties. One day she was driving the thing in the 1970’s and it got rear ended by an older lady, apparently the cops had to restrain her when they arrived on scene.
Apparently the first 27 production Corvettes were actually sold with hand-fitted resin and fiberglass bodies, as the production molds were not quite ready. Pretty interesting fact which makes the survivors of this group priceless concours residents today. Never been much of a 'vette guy myself, but have always appreciated the democritization and dedication it represents.
@bradleysoken: Balsawood between carbon fiber layers is actually extremely strong. Sort of similar to gnomex honecomb, the balsawood basically acts as a spacer.
@bradleysoken: One time when I was at college some friends and I were in one of the engineering shops waiting for everyone to show up for a team meeting. There was some aluminum and balsa wood composite laying around, this stuff is basically two very thin pieces of aluminum sandwiching some balsa wood with glue, and is very light and unassuming. My buddy had damaged a piece of it by slitting the top layer of aluminum so that it would easily break/bend. I didn’t know what he was up to, and he would not tell us, but we soon found out, he was laying in for wait for a muscle bound guy named Benny*. When Benny walked into the room, Jim* said "Hey Benny, watch this" and then smashed the composite over his leg and of course it broke. He then handed another similar size piece to Benny and said here you try. Benny smashed that composite on his leg about as hard as he could with both hands and … it didn’t break, but it sure sounded like something did. He was in shear agony.
Moral: Composites with Balsa wood are pretty strong and very light.

@bradleysoken: As nataku8_e30 said the balsa is sandwiched between the carbon fiber. It is probably end-grained not used in the plank like sheets that you see at a hobby shop or cheap rubber band propeller plane toy.
I worked in the luxury yacht industry and they used endgrain sheets like crazy for the strength, floatation, and sound-deadening between the layers of fiberglass or epoxy. The sheets looked kind of like the pre-glued tile sheets with the balsa already applied to a fiberglass screen to make positioning/ cutting easier...
@bradleysoken: Just so you know, on a pounds-of-load-to-pounds-of-weight basis, balsa is ridiculously strong.
It's old - really old - school technology to include a layer of balsa in your multilayer fiberglass layup. Separating the two skins by some distance puts the skins farther away from the center, so they do more for tensile and compressive strength. Its own strength notwithstanding, the balsa layer is really just there to separate the two skins. It makes for a stronger, less brittle layup.
It also makes the piece deader, less resonant in vibration. Think of just how loud and drummy a cheap fiberglass canoe sounds. Now imagine that that was the floorpan of your car. Ugh: no sale.

Somewhat off-topic, I saw a mouthy guy from Cali (in Indiana) get knocked out at a poker game not too long ago. It was more fulfilling than I expected.

There are some commenters who know a lot about various automotive fields. Some are even experts.
There are some who know just a little or perhaps nothing.
To me, that's what makes Jalopnik such a great place to intermingle with other automotive enthusiasts and even learn from them.
What did I learn on Jalopnik today? I learned that Corvettes have had transverse fiberglass leaf springs for years.

A gust of wind picked him up and carried him into the nearby powerlines. He was electrocuted to death. Moral here, metal cars keep you grounded.
