Our most popular flywheel option, CNC machined from EN8 steel billet. The clutch face has been specially machined to accept either an MED Bonded ClutchMED Turbo Clutch or our narrow-section Racing Paddle Clutch. It can be supplied with either pre-engaged or inertia ring gear, which is TIG welded in six positions after fitting. Complete with three spacers for the drive straps.

  • Recommended for high performance road and light competition engines.
  • Weighs approximately 3.66kg (3.69kg including spacers) before balancing - a considerable saving over the stock item.
  • Ring gear options allow you to use this earlier pre-Verto system with a later pre-engaged starter motor.
  • Supplied with steel drive strap spacers.

The MED EN8 Ultra Light steel back plate is now stronger and lighter than our previous design at just 1.32kg. These are suitable for use with all pre-Verto clutch and flywheel assemblies.

Recommended usage

Upgrading to an MED steel flywheel not only saves weight, but also gives a more durable surface face on which to grip the clutch plate. The lighter the flywheel, the faster the engine will be able to increase/decrease RPM, making it more free-revving and responsive to throttle input. The lightest possible clutch and flywheel setup is ideal for a competition car, whereas a road car will benefit from more flywheel mass to retain drivability in traffic. 

The entry-level MED EN8 Ultra Light is therefore an excellent choice for peformance road cars - lighter than standard yet still usable on a daily driver. It could also be used for light competition. 

This flywheel will suit all transverse A-Series engines (Mini/Metro) with a pre-Verto clutch setup. It is possible to convert from Verto to pre-Verto by purchasing the MED Heavy Duty Clutch Operating Kit. Please note - this will not suit fuel-injected Rover Minis. See the MED SPi Flywheel or MED MPi Flywheel for these cars. 


Pre-engaged or inertia?

This relates to the starter motor installed on your Mini. Inertia is the original style that uses a separate solenoid unit on the inner wing, whereas pre-engaged has an in-built solenoid. If you have one of our High Torque or Slimline starter motors, simply choose the correct flywheel to suit.

For reference, pre-engaged flywheels have 129 teeth on the ring gear, inertia types have 107 teeth.


Alternative options

The later Verto system introduced in the mid-1980s makes a good alternative for a performance road Mini. The steel flywheel itself is lighter than its pre-Verto equivalent, however the Heavy Duty Clutch Cover that accompanies it makes the complete assembly heavier. The Verto setup gives an easier clutch pedal, so overall it's a good alternative for road Minis.  

Moving up in the range from our pre-Verto Ultra Light Steel flywheel, we offer an EN24T Ultralite Steel Flywheel. EN24T offers greater tensile strength than our EN8 flywheel to reduce the chance of the flywheel fretting on the crankshaft in competition engines. The additional strength of EN24T also allows for extra weight saving, as we can safely machine more material away. 

Saving yet more weight is the MED X-Lite Flywheel, which features larger cut-outs and an integral ring gear for the starter motor.
