Upgrading your YSR big brake kit pistons to our stainless steel option allows for greater resistance of heat transfer and less brake fade. These can be used in any of our 4, 6, or 8 POT calipers from our Yellow Speed Racing Big Brake Kits. Our calipers pistons are available in standard aluminum, or optional stainless steel for increased temperature resistance. 

Choose your caliper size in order to ensure the proper number of pistons are ordered. (Kits sold per caliper pair, only available during the initial order of a big brake kit as an upgrade.)
