Big Brake Upgrades

[Slow and Slightly Angry]

I am looking into upgrading the brakes on my IRS coupe build. A majority of the upgrade is for aesthetics but the RSC coyote is heavy-ish and a good bit of HP so I want them to work. Has anyone done any big brake upgrade beside wilwood (i.e. brembo, baer, drag, street etc)? If so, any extra complications because of the choice? Have the upgrades been worth it? Use of the car will be mostly cruising, no autox etc.
I have a bit of non-wrench time on my hands right now so I have been running through a bunch of different options.
I do have the mustang performance brembo brakes from my donor but they will require at a min of 19" rim and an adapter.
