SneedSpeed R56 Race Axle — Passenger Side (Automatic Transmission)
Super Sport Ceiling · Race-Ready Driveline Component
The SneedSpeed R56 Race Axle — Passenger Automatic is a high-strength driveline upgrade engineered for R56 MINI Cooper S models with automatic transmissions. This axle exists specifically to remove the factory driveline as a limiting factor once engine output and traction exceed OEM design intent.
This is not a maintenance replacement.
It is the next step once power, grip, and driving intent move beyond Street-level assumptions.
Role in the SneedSpeed Trade-Up System
On the R56 platform, driveline upgrades follow engine output—not the other way around.
-
Street builds remain within OEM axle limits
-
Super Sport builds approach the ceiling of factory driveline tolerance
-
Race builds require a reinforced axle solution
This axle is positioned at the top of the ladder:
the point where the engine is no longer the weak link—and the driveline must keep up.
Why This Axle Exists
Factory passenger-side axles on automatic R56 cars are designed for:
-
Stock torque output
-
Moderate traction
-
Limited thermal and load cycling
Once boost, tuning, or grip increases, those assumptions fail.
The SneedSpeed Race Axle replaces the factory unit with a race-validated assembly capable of handling:
-
Sustained high torque
-
Aggressive launches
-
Repeated heat cycles
-
Track and high-load street use
Construction & Capability
-
Built to SneedSpeed Race Axle specifications
-
Rated for applications approaching ~450 horsepower
-
Precision rebuilt with reinforced internal components
-
Finished with a durable protective coating
-
Designed for direct bolt-in installation on automatic-transmission R56 models
-
Backed by a two-year unlimited warranty
This axle is designed to outlast the power level that justifies it.
Super Sport vs Race Context
-
In Super Sport builds, this axle represents the upper safety margin
-
In Race builds, it becomes a required supporting component
Installing this axle early prevents:
-
CV joint failure
-
Shaft twist under load
-
Unplanned driveline downtime
It allows the engine, tuning, and suspension to continue progressing without revisiting the driveline.
Applications
-
R56 MINI Cooper S with automatic transmission
-
Tuned N14 and N18 engines
-
High-grip tire and suspension setups
-
Super Sport builds approaching driveline limits
-
Race and track-focused applications
