Typically on a 6-Piston caliper, there are two of each piston size, so this combination should service one front caliper (6 pistons total).  These are not application specific, rather for those who may have a single torn dust boot or failed pressure seal or for those who are rebuilding their calipers; however, this kit will may work for many aftermarket Brembo or StopTech 6-piston caliper combinations.  Common applicatications are on the Porsche 991.1/2, 992 Carrera S, along with 718 GTS 4.0.
