New battery, worse handling

Although many sensitive drivers do notice subtle changes, those with m/c racing experience, and veteran m/c riders, tend to have a greater feel for their twins balance and handling.
Civilians and newbies not so much so -

Not sure how being a M/C racer enables you to feel a .37% weight difference in a car.
Besides (as you mentioned) noticing a very slight difference and the front of the car "diving like a rock" are not even in the same realm of consideration.

I could usually find the only prairie dog hole on the way home......

The horses were no help, they had been drinking fermented silage juice, that had seeped out of the bottom of a silo.....

An m/c when properly driven is connected to your brain through your body, and you feel the bike as an extension of your body, no sorry, a PART of your body.
The reason I bought the car, the closest thing to a motorcycle on 4 wheels (except the TESLA Lotus like bomb I was in a couple of weeks ago at the BRZWORLD meet).
.37 % up high on a car has more than .37% worth of affectation because of the height.
The main point is the human body can perceive much more than you think.
Just check out how fine a difference the human eye can discern.

Convinced, I'm going on a crash diet to drop 25 lbs so I can put in a lightweight battery and my car won't become unbalanced. -50 lbs of weight savings! Thanks! Shame I can't drop the other 25 lbs off my fat ass for fear of unbalancing the car

Also @Tcoat let people have their placebo. Now let me agonize whether or not to change the tire pressure by 1/2 a psi at the next event.

Yep the human eye can perceive a very fine difference. And the human brain can invent a difference that isn't remotely detectable because it expects there to be one.
By the OPs first post the car should be drivable with a passenger in it.

If you want nearest thing to a motorbike get yourself a Caterham. I moved from a bike to Caterham and I definitely recommend it. No other car will give you same thrill.

Much harder to get your hands on one in the U.S. and support is nonexistent except for a few specialty shops

Old formula style racecars are probably the closest thing you can get on four wheels to a motorbike in the US... they use the same engines at least. Maybe high end karts will give you the same kick in the pants. Street legal you're looking at adding a bunch of power to a Miata and that's about it.

Yum ! I wish. I would even take a Morgan LOL !
Last nights BRZWORLD meeting I was in a Polaris Slingshot that we will be tracking on our next track day, cant wait !

It can also invent a difference when none is expected. Sometimes I'll perceive a noise or vibration and wonder whether it's something new or has always been there. Some of us tend to be "automobile hypochondriacs".

How true that is. Every time I crashed my motorcycles, parts were broken on both the bikes and my body alike. Every scrape on the fairing felt like a cut on my own skin.
I only wish my body were as easy to return to 'as new' condition.

New battery: 40lbs
Old battery: 29.6lbs

Someone's bad at math.

Also, it's not going to make a difference as it's behind the front wheel and not in front. Having a passenger would be a HUGE difference compared to this.

Exactly, position of the battery is optimal comparing to other Subaru cars.

It would certainly make a difference if it was mounted at the bottom with the engine except up top just below the hood.
