They can be fiddly. But squeal is generally just miss alignment.. If I develop a howl or squeal it almost always goes with resetting the callipers.. also the Performance pads are quieter than Race
100 percent Magura MT7. But make sure you use the MRD-P rotors. I personally prefer the performance pad over the race. It might not last as long but I prefer the brake feel... but I dont see a lot of wet rides...mainly dust issues rather than moisture and grit
