Aluminium Frame for the SC cobras?

[CobraEd]

One of the things that made the real Cobras so bad-ass back in the old days is that they only weighed 1,900 lbs. Most of our replicas now weigh around 2,300 - 2,400 lbs. That is a 400 - 500 lb difference, or about 25% !!!! That is huge.

Think about how fast our cars are now, and then imagine if you took 500 lbs out of it !!!

I think the only Cobra that was in the 1900 lb weight range was the flip-top, yet I hear people throwing around that number a bit. I believe that the Kirkham cars with their high tech light weight billet suspension parts fitted with an modern aluminum small block engine is still over 1900 lbs.

Perhaps the 1900 lb number is just more Shelby snake oil legend.

Actually I think most replicas are in the 2500 to 3000 lb range.

As far as original Cobras and their weights here is what I show:
427 Cobra unladen 2350 lbs.
289 Cobra unladen 2170 lbs.
Autokraft/AC Cobra unladen 2469 lbs.
I'm not too sure about any original Cobras weighing much less than that.

What is your source for those number? And what does unladen mean?

I think the original 427's were very not very heavy

In addition to its benefits, titanium is more brittle than either steel or aluminum and you'd have to spend more on the frame than most spend on the entire car.

Weird as it may seem, most structural metals have a similar specific stiffness (stiffness/unit weight). There is no advantage to using one over the other except for gaining strength.
