MED MPI INJECTION ULTRA LIGHT ST1

The MED SPi Mini flywheel is CNC machined from EN8 steel billet and weighs just 4.25kg, for a noticeable improvement to acceleration.

The standard Rover flywheel features a separate reluctor ring, which can move and affect the ignition timing. Here the teeth are machined directly into the flywheel, to very close tolerances, to maintain accurate ignition timing.

This kit comes fully assembled and dynamically balanced to within 1 gram on our in-house balancing rig, ready to run.

Stage 1 is ideally suited to a multi-point injection Mini (1996-2000) producing up to 80lb.ft torque. 

You'll instantly notice improvement to the car's acceleration off the line, while the precision balancing will result in smoother running engine. The clutch is perfectly usable for everyday traffic.
