I read about that build, fascinating engineering, and I'm glad that some of the processes trickled down. This must have been the impetus for a lot of that 200 lb weight savings. Do you know how much your car weighs?

Good points, mea culpa. I'd read that thread a while ago, but that piece slipped my mind. Thanks for pointing that out.

Ok, so the aluminum parts in the ERA save you about 100, then you could also go with an aluminum engine and some other bits to shave a bit more.
Summing this up, it looks like the Kirkham saves ~150 on the body vs the glass cars, and then the billet alu suspension, brakes, and other accoutrements account for another 100-200, depending on how extensivily those are implemented.
