Any plans for 2.1?

Ditto, I love this mod , and am saddened at being unable to use it anymore.

I believe you can just modify info.json inside your copy of the mod. Change factorio version from "2.0" to "2.1".
It doesn't work for every mod and sometimes stuff breaks. Like in this mod the tire tracks are no longer present while drifting in 2.1, at least for me.

I think the tire tracks not showing up is a issue that already is there in the latest stable version, I only updated my game to 2.1 experimental yesterday and for that entire game I'd never seen tire tracks.
