Not sure which compound you need? The Wilwood brake pad compound guide covers what each one does, which are cleared for street use and which rotor materials each can safely run against. The Wilwood brake pad plate, caliper and thickness guide lists every plate shape against the calipers that take it.
Fitting and bedding
Wilwood supplies most racing pads unbedded. Bed a new set in before trusting it at speed with a series of progressively harder stops from moderate speed, without coming to a complete halt, then a cooling lap with the brakes released.
