SneedSpeed R56 Street Series Piston Ring Only Set
Street & Performance Street Applications
The SneedSpeed R56 Street Series Piston Ring Only Set is a precision-engineered piston ring solution designed for R56 MINI engines including N12, N14, N16, and N18. Sold per piston, this set restores critical combustion sealing and oil control in engines where the piston itself remains serviceable.
This product exists to re-establish proper engine function without over-specifying components or altering the character of a street-driven engine.
Function & Scope
Piston rings control:
-
Cylinder pressure sealing
-
Oil film regulation
-
Heat transfer from piston to cylinder wall
When rings wear, compression drops, oil consumption increases, and drivability degrades. Replacing the rings restores the engine’s baseline behavior while preserving factory piston geometry and operating characteristics.
This set is intended for engines where:
-
Pistons are reused
-
Bore condition remains within specification
-
Reliability and longevity take priority over extreme output
Design Characteristics
-
Street-balanced ring tension for predictable sealing
-
Optimized oil control for daily operation
-
Materials selected for consistent performance under normal and moderately elevated loads
-
Compatible with OEM and SneedSpeed Street-series pistons
-
Sold per piston for precise quantity matching
The ring geometry and material selection prioritize stable compression and oil control without introducing unnecessary friction or wear.
Where It Fits
This ring set is appropriate when:
-
Refreshing an engine without replacing pistons
-
Completing a street-oriented rebuild
-
Correcting oil consumption or compression loss
-
Maintaining factory drivability and response
Engines operating beyond this scope require different piston and ring strategies.
Applications
-
R56 MINI platforms
-
N12, N14, N16, and N18 engines
-
Street and performance-street builds
-
Partial or full engine refreshes
