Manley 2013+ Subaru BRZ 86.50mm +.5mm Bore -11.4cc Dish 10.0:1 CR Platinum Series Piston Set

Manley's Platinum Series pistons start with domestic 2618 alloy forgings, a material chosen for its exceptional strength and performance under high stress. These pistons are specifically designed for the 2013 and up Subaru BRZ, featuring an 86.50mm bore size with a +.5mm overbore. The dish volume is -11.4cc, which helps achieve a 10.0:1 compression ratio, a common target for naturally aspirated or lightly boosted builds looking for improved response and power without sacrificing too much drivability.

You'll find that Manley pays close attention to the details that make a difference in engine performance and longevity. The pistons feature proven cam and barrel skirt profiles, which are shaped to reduce friction and wear on the cylinder walls while still allowing the piston to move freely. The ring lands and grooves are machined to very strict standards, which is critical for ensuring a good seal between the piston rings and the cylinder wall. This improved seal means better combustion efficiency and more power. The included wrist pins are made from premium chrome moly, offering solid durability for most applications.

When you're building an engine, especially one that will see hard use, the quality of the internal components is paramount. Manley's unique fixturing process allows them to machine the skirt and the ring grooves in a single operation. This ensures that the ring grooves are perfectly square to the piston skirt, which further enhances the ring seal and contributes to overall engine health. These pistons are a popular choice among professional engine builders and tuners who demand reliable performance from their builds.
