The MED Stage 1 X-Lite Assembly includes our lightest EN24T competition steel flywheel, back plate and MED organic competition clutch plate. It's the ideal setup for high-end trackday cars or full competition usage. 

We always recommend an EN24T steel flywheel when using one of our EN40B steel crankshafts.

The package is expertly assembled, centralised and dynamically balanced to order. 

Kit contents:

  • MED X-Lite steel flywheel - 2.50kg.

  • MED EN24T steel back plate - 0.87kg.

  • MED organic competition clutch plate

  • Competition orange clutch cover.

  • Nine high quality drive straps.

  • Six EN16T steel drive bolts.

  • Full assembly and dynamic balance.

To install without disturbing the balance, remove the large washer and spring clip from the diaphragm and there is no need to disassemble the clutch/flywheel to install the bolt.  

Flywheels are supplied with a pre-engaged starter motor ring gear only.  Please see the additional information tab for further specifications.

If you'd prefer a grey diaphragm and paddle clutch plate, look instead towards the MED X-Lite St2 kit

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 MED EN24T X-Lite is ideally suited to full competition usage - we would not recommend this flywheel for normal road usage as it's incredibly light. 

The St1 X-Lite kit is popular with Mini Se7en racers or 1275-based trackday cars with upto around 120bhp. For higher power outputs we would recommend upgrading to the St2 kit, which includes a grey diaphragm and paddle clutch plate.

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.
