:wavey I had squealing issues with cross drilled and slotted rotors and FrictionMaster ceramics (2 sets); Werever ceramics (1 set). It took $125.00 on f & r sets of :worshipWagner ThermQuiets :worshipand a resurfaceing job to experiance...I've been looking at the powerslot rotors along with the hps ceramic pads for my shelby GT. I previously had the hps plus pads on my subaru legacy gt and while it stopped great, the pads put out a tremendous amount of dust, constantly squeaked and had to be replaced after just 20k miles. Does anyone have any recommendations on a decent setup? My driving consists of about 60 percent highway/40 percent city. Thanks.
