I have considered that, but I don't think I would gain much as the new Lithium Ion batteries sound like the perfect fit for me. I'd also prefer not to have to store an extra battery all the time and then buy 2 new batteries since mine might only have one winter left in it. Would I also lose all of my radio presets and nav entries every time I fully disconnect the battery?

The battery issue isn't a big deal. I own a boat, and store 2 of its batteries during off-season. One is a standard lead acid starting, the other is an Optima marine blue. Both are from 2007, and still pass the yearly inspections I get on the boat. I keep them on a basic battery tender. Personally, I can't believe BOTH batteries have lasted so damn long, I am very hard on both of them. I would have thought 5 years to be good.
For cars, there are many devices that can be purchased to inject 12vdc into your cigarette lighter or OBD2 port to energize the standby circuits in your car whilst changing a battery to prevent setting loss. (BTW why the HELL don't manufacturers, including aftermarket, have memory backups or ability to save configs to file? what a PITA to go through and get everything right again!!)
Just be sure to not short the battery leads as you are exchanging batteries, as that can blow a fuse, or at least drop 12v long enough to delete settings.

It’s probably because memory storage is a new theory just coming to market and auto makers haven’t realized that consumers love simple convenience. Good call on the standby circuits, guess it’ll have to do until they open their eyes.

Somewhat likely, but my boat is harder on batteries than my newer cars are. My boat has 2 pumps, an inverter, GPS, scanner, big stereo, cabin lighting, etc. Only a few circuits go offline when key-off. Most things can be turned on without the key being "on". Only difference with a car is that I monitor both batteries constantly, and I have a good isolation system.

My point is that you shouldn’t have to save it externally. It really wouldn’t be hard for them to set up non-volatile memory for onboard systems... already have it for your odometer.

Really? Well this is interesting. But does the flywheel make more noise? I thought about this when they had my clutch out and replaced the slave cylinder before, but every review I could get on this car said it was a lot louder- like a cement mixer rolling around. Thoughts?

Sorry replied to a reply you made buddy. It doesn’t show the message you replied to. Lol it would make sense if it did. O well just wanted to add that it was couple lbs heavier.
I am in the process of weighing the front and rear diffs that I’m swapping in from g35 rear lsd and g35x front (3.69 ratio instead of stock 3.35). The front feel soooooo light. Haven’t felt the oem g37x sedan diffs yet so it might be just as light but I mean it’s light. Front had a ship weight of 30lbs, rear was 100lbs. Just fun fact. I’ll post oem g37x sedan diff weights after the swap

Id have to agree! Love mine. Along with shifting and whatever else it also helped me create more clearance near headers and in turns. They fit x sedan also which blew my mind! I had done everything possible besides switching to new brand header. Turns out all I needed was the motor mounts
