I would be pursuing the lemon law or asking for a new unit then.

The problem is that it seems to affect most ZL1s. I swear the 2 other 2018s I drove (an A10 and an M6) before I ordered mine did it. Mine did it on day one — or as soon as I started making pulls from freeway speeds. Definitely not a problem with the clutches in the diff or anything. Mine has no problem roasting a set of Mickey Thompson drag radials at the strip.
I’m not 100% sure yet, but I think mine’s been cured. I aligned my car early on (~1500 miles) and it didn’t go away. So I figured it must be some weird software thing with the diff. It would really only do it nailing it from a roll at certain speeds. No problems at the drag strip on my 10.79 pass. Fast forward 3000 miles, and I decided to align my car again. This time on our brand new Hunter machine we use for Porsche’s. Shit was toe’d out in the rear, and had massive front toe in. We were having calibration problems with our old Hunter machine for several years, so I don’t really know what the deal is. I’m guessing the alignment I did on the old machine was always off. That or it somehow moved on it’s own. But rear toe out can definitely cause stability problems under WOT. I’ve seen that on M3s back in the day. Don’t want to knock on wood, but I haven’t been able to reproduce it since. My car loses traction really easily, so it’s sometimes a little hard to tell. |

That wiggle in the rear at highway pulls is a buzz kill for me since it’s really one of the few times I beat on the car. I don’t do road course so it’s twisty back roads and highway pulls for me. I don’t see myself keeping this car forever like I want to if I can’t figure this wiggle out.

The USA cars have different programming and this upgrade is VIN applicable. Even if I took my car south, I couldn’t get it done. Somebody please explain this! What or why are the USA and CAD cars sooo different?!

I'm pissed we actually have to pay for this one.
Seems more like a fix than a mod. This was my biggest issues on the 17 I had. |

Same here. The 17" drag radials on the rear make it 10 times worse. With the stock rears, it barely moves and I can pretty much just keep the wheel straight, but with the drag setup (rears only) it's all over the place. I have to actually make steering corrections to keep it in my lane. The weird part is that it doesn't always do it and it's really bad sometimes and then barely wiggles others. It seems to be relative to how smooth and even the surface is. Both my local track here in London and Clay City, the rear was all over the place. Both tracks have older surfaces that is likely not nice and flat. Bowling Green completely resurfaced their strip and the car tracked perfectly straight every time during Camarofest.
If it's being caused by uneven surfaces, unhooking the front sway bar might fix it (at least at the strip). These cars are super stiff and it doesn't take much of a dip to unload one of the rear tires. So at full throttle, it makes sense that it would take way less to cause one tire to have less grip than the other. I just might have to give this a try one day and see if it helps.

I/we have to start realizing that there might not be a fix for this wiggle. Since this car is mostly designed for aggressive track driving it is not going to handle like your average car under certain circumstances.

I have a SS with magride trapping mid/low 120 depending on weather. So it might not be fast enough or have enough torque to expose that be behavior on 17” et street ss and haven’t felt that. I do have a set of softer side walled Rs ready to go...so we’ll see |

It's annoying they sell this and you have to go in for it to be flashed. More manufacturers need to get on the modern train and start doing OTA updates like Tesla. As they make software improvements, just let our cars download them. its freaking 2019. Imagine if you had to bring your phone, laptop or any device into the dealer each time you had to update it.

A little update. I had the car aligned, and the side to side wag is gone. Hadn't been aligned in 2400 miles. Thay said it was way out of whack. Going to align it more frequently .

So im having the eLSD calibration installed at the moment and Chevy is quoting me $415.00...$280 for the technology and an hours worth of labor. Anyone else have this same experience? Slightly different than the $350 i read about..
