MED VERTO ULTRA LIGHT ST2

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.

No, changing the flywheel has no effect on the power output of the A-Series engine, however it does increase responsiveness and acceleration by reducing rotational inertia. Reducing weight from the flywheel in particular has a far greater impact on acceleration of the Mini than weight loss elsewhere, so is highly recommended for all performance Minis.

The MED Verto Ultra Light is our preferred option for performance road cars, although they have also been used extensively in competition. The flywheel itself weighs approximately 2kg less than the standard type, while the later Verto clutch arm design gives an easier clutch pedal than the early diaphragm type.

This flywheel has 129 teeth on the ring gear and is designed for pre-engaged Mini starter motors only, either standard-spec or aftermarket high-torque units. Standard pre-engaged starter motors can be identified by an in-built solenoid, and were fitted from the advent of the Verto-style flywheel in the early 1980s. Be careful with budget-grade replacement starter motors, as flex in the starter motor bendix can damage the ring gear teeth. We would recommend using either an MED-5200-HTP or MED-5240-MP starter motor if you're looking for an upgrade.

Yes we do sell all of the components separately, but would highly recommend purchasing a complete kit, as it is setup, balanced and ready to fit. The included clutch cover is not a standard-spec replacement, but fully rebuilt to our own requirements to improve overall balance, torque holding and concentricity. A large proportion of a Verto assembly's weight is in the clutch cover, which fits between the flywheel and crankshaft, so alignment and balance are crucial.

These are machined from certified EN8 steel billets compared to the cast iron originals. As a result, we can reduce the overall weight far more than is safely achievable on a standard flywheel, which are brittle in comparison. The ring gear teeth are also machined into the steel, then specially heat treated, for much improved longevity.
