This is a feeler for interest in rear swaybar adapters for the Bolt.

I plan to fund manufacturing of adapters that allow easy installation of a rear swaybar on the Bolt, such as the Cruze swaybar by Whiteline, as sold by EV-MODS and others. The adapters are dasto's design, as shown in another thread.

This should make the car feel considerably more nimble and willing to turn, for autocross or just fun use on twisty roads.

At this point I don't know what the price should be, but I'm guessing in the neighborhood of $75-100 for the adapters. I'm currently waiting for a prototype to be shipped to me, so this will most likely take several weeks to get to the point of taking orders and shipping.

I'm presently soliciting interest to get a sense of how many I should expect to order from a machinist.

Please reply here with a note indicating your interest in such an offering. As the project progresses I'll post availability and pre-payment price here.
Interested in them

If anybody is interested I ended up doing a little testing to quantify the stiffness that the swaybar adds to the rear axle. The end results were the addition of the swaybar increased the torsional stiffness of the axle by 44%.

Long long ago (think "1970") are used to buy rear sway bars from third parties install them on my sleeper/performance ICE cars.
personally, as far as I’m concerned, the handling of my 2021 Bolt in factory form is **** good, good enough that I wouldn’t bother. I’m of the “if it ain’t broken, don’t fix it” school.😏

also, note that there is at least one vendor already supplying rear sway bar for the Bolt:
BHR93 Whiteline Rear Swaybar 22mm For Chevy Bolt, Chevy Cruze, Chevy Volt

I suppose if I was doing autocross I might be more interested.
Before I hack sway bar in, I’d go for different tires.
Note that the bolts OEM rear suspension is described as "Compound crank (torsion beam)…"

and if I remember right, there is a downside to having a stiff anti-sway bar:
It’s making the independence of the independence suspension less independent. Not so good when one rear wheel hits a pothole.

I have other fun cars : Stripped out STi, 2jz gte powered lexus monstrosity, 911 turbo for fun. I don't believe that this modification will improve the handling much because of the suspension setup in the back but what I dislike is the disconnected feeling mid corner especially if there is a mid corner bump and you are leaning hard on in it. It's only so both sides are connected and the chassis doesn't feel unsettled as much in these situations cause I like to go around with my bald head on fire haha.

The bar from evmods or anywhere really needs to be drilled out to install in a bolt. The adapters will offset the hole so that the cruze bar will mount with existing holes.

I had the bar. I was really trying to see a difference and I could not. At least nothing significant.
Yes, there was extra stiffness, but it was minimal.

Some claim it is a lot.

I would rather use LSD than the bar...
