I assume these are 4 piston calipers. I would look at the bore size on the calipers. I've seen some of their stuff with smaller bores than what the Strange and others use. Makes a difference in clamp pressure and MC size needed. Got caught with that years ago, once.

As far as pads, drag race stuff is usually formulated to work well cold since brake temps are not an issue, as opposed to road race/oval/street applications. Strange recommends a soft metallic for best holding capacity on a drag race front brake.
