2018 and 2021 ZL1 differences
Other than tail lights and rear view mirror camera, are there any other differences between the '18 and '21 ZL1's? Considering trading/selling mine for a vert.

The convertible ZL1 does not get the eLSD (it gets a regular limited slip diff), no PTM (performance traction management) and smaller anti roll bars. I think the performance data recorder isn't available for the convertible.

No homelink (garage door opener) in the 2021.

Chassis is stiff, no cowl shake and hugely capable performance.
95% + performance of the coupe. Open air driving experience is what I wanted. Hard to fault the vert. Lots if grins. Can't go wrong. |

The ELSD adds weight, complexity, as well as size that cannot reasonably be fit under cross bracing, so that was eliminated. Unless you’re racing, you’ll never notice not having it. The vert diff does have a heat exchanger. The 2019 and up verts - rear view camera. The one down side is if you want to keep the camera and change the spoiler. I haven’t found a reasonable way to do this (yet). |

Either way. Still a capable and fast convertible.

A10 trans is not able to be tuned on the 2020+.

That is a blanket statement at best.

If you switch to a larger camshaft which normally shifts the power curve to the right, Ideally you want to bump up the shift points to utilize the increased power range and maximize the cams potential. Also depending on camshaft selection, it may require a higher stall converter. Different power adders benefit from higher stall converters such as F1a94 prochargers which seems to be a popular option on this platform. All scenarios I have pointed out here would require transmission tuning to maximize their potential. Does that mean you have to...NO. I am sure there are packages designed to work around the parameters of the stock transmission tuning but it doesn't really have anything to do with a power number alone. There is more to going fast then a power number.
