I have an early model 2011 with Rev D ESCL (steering lock). It is not covered under the recall, so you'll want to remove the fuse if you wind up with one. The ESCL was removed entirely later in the 2011 models. I'm pretty one of the steering lock threads has dates but I couldn't find them in a cursory search.
I also have the Z1 CSC elimination kit (~50K miles on it), and I will be switching to the ZSpeed CMAK whenever my stock clutch is done. I would recommend either ZSpeed CSC aftermarket option over the Z1 kit based on my experience
