Excellent, excellent!
I got the Whiteline rear swaybar installed, and it changes the car quite a bit in the Mini-Cooper direction. Between the Bilstein shocks and the swaybar, the car now corners much flatter with very little body roll, and is much more pointable as a result, i.e. there is a more linear connection between the amount you turn the wheel, and the line the car takes through a corner.
It took me a few minutes and a few corners to change habits from two years and two Bolts – whether you notice it or not, when you turn in with a stock Bolt, first you turn the wheel, then the car starts to turn and leans toward the outside of the corner, and that changes the line the car follows, so you have to adjust with the wheel to maintain a consistent turn radius. It's a bit like turbo lag, but for turning, not acceleration. It took me a few corners to become accustomed to the car actually going where I point it.
Unfortunately, these adapters to fit the Cruze bar to the Bolt without mangling the bar are not generally available. Mine were developed by dasto for autocrossing his Bolt, and I bought them from him. There are no design drawings for the adapters, aside from those that I measured from the parts I bought from him.
If you are enterprising enough to get a set of adapters made up, you can find my measurements in this thread: Interested in rear swaybar for Bolt?
Here's a picture from dasto of his installation. Other images can be found on evmods.com, where you can purchase the swaybar, although I would not consider drilling holes in the bar to install it the way he did.

Not being a SA but have found same handling improvement when carrying patio stones, furniture, or big haul from Costco.
What does this imply about suspension? As this is not my purview

Yes, agree, a rear bar makes the car more responsive and turn in more immediately.

Do you live in an area which has real winter weather? A rear bar also increases oversteer on slick roads.

Yes, Portland gets around 4"of snow a year, and plenty of ice, but I grew up driving in Chicago - not worried about it.

I matured racing my beloved Porsche
Oversteer is my thing
If I am found worthy of engagement, I need oversteer and advice
Best

What to do to get a dialogue?
I am interested in the handling want to discuss more but nada?
So I say self, Self why do they use a sway bar on a SOLID REAR AXLE? and what could it do?
So self I say, Self this is interweb bs because a solid rear axle is IT'S OWN SWAY BAR
Glad we had this little talk.
Over and out

sparks: your self seems to believe that the Bolt has a solid rear axle, which it does not.
Back here in reality, it has two independent trailing swing-arms, each with its own spring and shock absorber.
Take a look under the car some day - you might be surprised at what you find there.
Here's Chevy's description:

Rear Suspension:

Compound crank (torsion beam) with coil springs

Not remotely the same as a solid rear axle.

What? Only engagement is when you want to slam me. Where were you when I requested a dialogue
As I was taught in finishing school
God bless you

Bolt Rear Suspension - Compound Crank (Torsion Beam) with Coil springs

In the broadest sense, torsion-beam rear axles are a variant of the rigid axle.Torsion-beam rear axles primarily consist of two bend-proof, torsionally stiff trailing arms and one transverse profile which connects the two trailing arms with low torsional stiffness.

Isn't the Bolt rear suspension a hyprid in that it uses both a torsion beam (which functions as an anti-roll bar) and coil springs which are the primary load carrying element?

(BTW, I've surrendered to Wikipedia's mis-mash and no longer maintain it's an anti-roll bar and not a "swaybar")

An anti-roll bar (roll bar, anti-sway bar, sway bar, stabilizer bar) is a part of many automobile suspensions that helps reduce the body roll of a vehicle during fast cornering or over road irregularities.

I believe that this is correct and it's the "low torsional stiffness" that is is the issue. The torsion beam is probably the black bar running laterally in front of the trailing arms.
The swaybar between the trailing arms acts like a swaybar on any vehicle - it adds to the roll resistance, creates oversteer, and greatly improves the precision of steering as a result.

Engagement: wait for EV-MODS to release his promised Bolt-specific swaybar and install one. It makes the car lots more fun to drive on twisty roads. If you think it is "Internet BS", then don't.
