Hi bro. Im not into 4k that much, i mean its great but i dont have a good tv for 4k (yet) but il say that you need to look for framestor and wildcat releases. Il say probably TorrentLeech or TorrentDay could be a good place to look for framstor releases. And for wildcat you need Blutopia. You can also find really special stuff there. if you are a movie guy, youl love it.
