Typically on a 4-Piston caliper, there are two of each piston size, so this combination should service two rear calipers (8 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.
Please contact us for application-specific kits and we will be happy to help! Also, if you have any requests for kits to fit other calipers, email us and we will see what we can do for you!
