MCS never really sorted out a good solution for securing the brake line or sensor wire. They added those threaded standoffs to the strut ears when I asked them to redesign the ears for more clearance, but the brackets they had didn't really work for the line placement.
My solution was to buy zip ties which have an additional hole, and some M5x0.8 screws to use with the standoffs. I have them chained so they wrap around the strut body. It's the best I've come up with so far, and was readily available at my local Ace Hardware.
