The pads need to held more firmly in place to prevent
the low speed squealing. You can put pressure on the
inside of the pads to push them up against the
pistons firmer by putting a spring over the cotter
pin to push out on the pads....also, use plenty of
the anti squeal stuff on the backing plates.
People seem to forget that big brake setups are really intended for racing type applications. Wilwood calipers are designed to allow for quick pad replacement not really for luxury
I am happy with my fastbrakes setup... they are not noisy at all....you get some chatter after very high speed stops but the performance is great...i definitely recommend the wilwood pads over any EBC pad though.....
