Quality parts OP, and I like the part list in your signature. Nicely done.

It'd be worth your while to get adjustable end-links if you are below stock ride height, otherwise the sway bar will bind.

I usually advise against the M3 rear sway if you have or are planning to get coilovers, as I think it makes the rear too inflexible. The rear needs some flex to keep power transmitting to the ground. You may be OK depending on your spring rate. Drive around with the rear sway disconnected and see how it feels. I'll likely change my rear spring rate if I find my new setup too stiff (logically I'd ditch the M3 rear sway and go back to stock but it's such a pain in the ass to drop the rear subframe; cheaper to just change springs).
