2 piston aluminum calipers are designed to replace the stock cast iron caliper. It is 5 lbs lighter, produces better stops and will improve ride quality. 5 lb lighter caliper will reduce more weight than going to an aluminum wheel(3-4 lbs lighter). Will fit in 15" wheels and with powder coat, look much bester behind the wheels. The pads we use are North American made and are designed for great initial bite and low dust. Slotted rotors are standard and help improve pad life by sweeping dirt, stones and other debris from the pads. When pads are cleaner, they last longer and work better Please note: Master cylinder will not bolt to stock booster on vehicles with O.E. power drum brakes
