I agree but I'm talking from the factory:lol:

I feel a 1 piece driveshaft was another way foy weight to have been reduced from the factory.

I think thinner glass could have been used as well. Unless there are regulations governing thickness. A slightly smaller washer fluid tank (I think someone mentioned that), could have shaved some pounds.

Of course I would have loved to see aluminum arms in the suspension, but my guess is that it would have increased costs.

The glass is already pretty light.

Btw I love your build! Very happy to have you chime in as you've seen the innards of the car in good detail.

Yup you're right, I just pulled the one from the vendor, here's a Shorai battery for a bike at $185 that some guys have used. The SuperB I was thinking of seems to be for heavier duty applications, with this Shorai it sounds like there is a risk that it won't keep up with some rigorous demands but if you're going for all out performance then the compromise is worth it.

Amazon.com: Shorai LFX Battery - LFX21A6-BS12/Black: Automotive

I've been using my Shorai for exactly 2 years. Daily driven over 3 seasons, no issues.

To the OP, these are the major things I've done which could've been done at OEM:

Flywheel 12#
Driveshaft 13#
Wheels/tires (33lbs/corner) 28#
Brakes 12#

Battery 25#
Rear Seat Delete 25#
Spare and tools 25# (+5 for a continental slime/inflator kit)
Smaller Windshield Washer Tank 2#
Lighter Rear Exhaust 10#

~152# down without much loss in functionality. ~66# rotating weight loss. ~40# unsprung/rotating weight loss.

Not sold it to fat americans

I have also been using my Shorai without issue since November 2013. I don't DD it though. But I'm also using the iddy biddy one that's meant for four wheelers and jet skis. I really feel like car manufacturers could switch over to lithium iron. I realize some people live in colder places than I do here on the Gulf Coast, but that little thing cold-started my car in 15°F successfully. I'm sure one twice as big could handle any DD scenario for the long term. They're a bit more expensive than a traditional battery... initially... but they last longer so are probably cheaper in the long run.
