Piston for caliper - stainless steel 2.125'' dia
Made from stainless steel these 2.125" diameter pistons have very low thermal conductivity and an excellent corrosion resistance. In addition they are machined with cut outs to reduce surface area and heat transfer. This also allows air to pass between piston and pad for extra cooling. They are lightly waisted internally to reduce weight. These are the best pistons available.
