Typically on a 4-Piston caliper, there are two of each piston size, so this combination should service one caliper (4 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 4-piston caliper combinations.


Common Applications include 991.1/2 GT3/RS, Turbo, and GT4's.
