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.
