I've just recently had the RCLT kit installed on my 2013 Tacoma and I have the stoptech big brake kit.
Ran into a few issues and I'm still testing and flexing to see if its going to work.
There is a thread about RCLT and BBK in the RCLT area.
It's called Big Brake Kit

I did find a banjo bolt with a lower profile.
Had to notch the lca.
