Too many unknown variables to compare the race car to a stock ZLE. What is the weight distribution, tire pressures, camber/caster, did they change the section width of the tires (did they keep the same stagger), etc. The suspension is a system. Change one variable and it will affect the handling characteristics. It's common for race teams to rely on the sway bars for the last bit of fine tuning. They may have ound that their foundational system was a tad oversteery so they deleted the bar. Could have also been a weight reduction intention.

Without the benefit of experimenting with the stop watch this is all bench racing. But I would think that the millions GM spent to fine tune the ZLE should be an indicator that the rear bar is essential to the overall performance in OEM trim, track alignment specs, tires, tire pressure, etc. The ZLE rear bar from the factory is in the medium setting. They gave us one option to stiffen and one to loosen the rear, in an effort to allow owners to find their preferred performance.
More than that and I believe it will adversely influence neutral handling on a stock ZLE.

If you decide to experiment, please lay down baseline laps. Change sway and run comparison laps. That's the only way to know.

Ive taken mine off for drag arcing to let the front rotate better, but for DD or road course, it might push on entry and kill the center off.

Firstly: "Way more stable" means different things to different ppl. Maybe Phoenix set it up loose and/or with small bars to start with. Tons of possible variables here, so focusing on a single comment without any broader context is like chasing shadows here. BTW Taking a rear bar out has been a popular mod for wet races for decades. Nothing new here (softer means more grip). But all things being equal, it will introduce a huge push by design (as mentioned already above). Unless the balance is compensated for elsewhere (and it better be done for a specific and good reason).
Fast cars are all about balance and confidence.

I think the operative words here might be "completely race prepared". But not in the sense of understeer budget / understeer-oversteer balance or even "stability".

I'm thinking that in a W2W race, once you own the corner it matters less if you're slightly slower midcorner if you can jump off the corner harder.

It's not the same situation at HPDE or time trialing, where your laps are basically qualifying laps on a qualifying line with no position defending or racecraft/strategy involved.

Even for the ZLE, Chevy needs to pay some attention to the ride vs handling balance.

A rather heavily modified car like Nicky's, not so much, and for an all-out W2W racer like the Phoenix cars maybe not at all.

If you really want to answer the question just take one of the rear links off next time you head out to the track and tell us what it does lol.

Nah...lol 😆
