StopTech Street Performance brake Pads are engineered to meet the demands of high performance driving while maintaining the refinement and comfort expected in everyday driving conditions. StopTech brake pads combine the benefits of premium street brake pads with aggressive friction formulas suitable for track day and autocross use. Para-aramid composites are specially formulated to provide linear response at both cold and hot temperatures, delivering optimum stopping performance over a wide range of driving conditions.
These are the same pads Stoptech include in all the BBK's they sell.
There is no need for a sale, as they are already very well priced:
