MED ST3 CAMSHAFT KIT - 1.5 ROCKERS
( £416.67 EXC VAT )
The MED Stage 4 Ultra Light Assembly includes an EN24T steel flywheel, backplate and Race Paddle clutch plate. It's the ideal setup for trackday and competition cars with a pre-Verto system.
The package is expertly assembled and dynamically balanced to order. Simply remove the diaphragm washer and spring clip before installation and there is no need to disassemble the clutch/flywheel. Don't forget to refit the washer and clip after installation.
The package includes:
Flywheels are available with either a pre-engaged or inertia-type starter motor ring gear.
This is the top-of-the-range MED Ultra Light Steel flywheel. For the next upgrade, see the MED X-Lite range.
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 mid-range MED EN24T Ultra Light is therefore an excellent choice for both high peformance road cars and competition usage.
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.
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.
For full competition usage we would recommend the MED X-Lite Flywheel, which features larger cut-outs and an integral ring gear for the starter motor. This is also machined from EN24T but is far lighter.
