Prior to purchasing my Power Stop calipers, I had Saleen 15 inch, 6 pistons on my truck. Believe it or not, the Power Stop calipers, with EBC Extra Duty Brake Pads and EBC Sport Rotors performed equal to the big calipers. Unbelievable and a better price point overall. I am now a Power Stop fan for all of my upgrades and will refer them to my friends. Awesome Product!
