Im really interested to see what StingrayComposites comes up with for either a carbon t-top of 1 piece targa... The factory tops are pretty heavy and are the "highest" weight on the car.

On another note, I chose to do the fuel lines in my car with aluminum tubing over steel or stainless... a roll roll of the alu tubing is notably lighter than the stainless roll of the same length. Thats a PITA job for marginal weight that is already down low though

Not a fan of aluminum tube fuel lines. The marginal weight reduction doesn't make up for the compromised safety, IMHO.

Which brings to mind this recent scary event. A friend, who has just finished his experimental airplane build, suddenly lost power at about 3k ft altitude. After going through proper protocol, he looked down and saw an old airfield with big yellow X's on the runway below him. He immediately dead sticked the plane down, successfully landing with no damage. He left a trail of fuel the length of his landing. Turns out he had a broken aluminum AN coupler in the fuel line. Looking at it, it appeared to this EE to be a fatigued aluminum tube within a swivel female to female coupling.

I told him not to bother buying a lottery ticket in the future, because his luck is all used up.

I don't recall ever changing the fuel line in my '72 vert....but did have the rear brake line fail, right under the driver seat, so got two lengths of brake line, spliced them together with a brass fitting, I forget if compression or flare, probably flare.....no biggie....but an ALUMINUM fitting?? don't think I ever seen one, let alone USE one.....

Well? If you look at modern fuel injected cars, you will rarely find some steel in them, they even are in "plastic" ! And alloy is certainly easier to bend than S/S !

Going on my car from a 1" front bar to 1.1/4 gained 6.60lbs more !!

Have you checked the weight of the alloy hub on the original steering wheel ?
1.54 lbs!!

I did replace the hardtop glass window ( 9.26lbs ) with Lexan , and not refitting the roof lining ( 13.99lbs ) as well.

Another funny one is the original radio + speakers = 8.81lbs

Electric window mechanism + motor per side = 8.70lbs . I should have check the elec motor alone, as I am still using the manual mechanism.

Removing the protective tar from underneath the body an wheel arches = 3lbs!
But the weight of the roll cage = 21.27 lbs

A China made radiator frame =12.5lbs Original =13.9lbs See!! China stuff is really good !

Brake master cylinder Iron= 8.59lbs Alloy = 3.74lbs

Another that you don't see too often on Vette anymore, is the hub cap of the rally steel wheel = 1.76lbs + wheel trim at 1.32lbs = 12.32lbs for 4 wheels !

Definitely trade-offs.

A carbon fiber convertible top and deck lid could save some serious weight. Like this unit:

Window delete could be an option, but it probably increases drag.






I’ve got two deck lids, 1 stripped and 1 complete. I’ll weigh them later.

Convertible deck lid

With all hardware: 28 #

Stripped: 22#

So a one piece top and deck lid could save a bunch.
