Other than to get a flat face for the clutch pressure plate/cover the majority of metal for lightening is removed from the rear of the flywheel.
So if you already have 1098cc engine/gearbox - get the flywheel lightened and you will experience a vast improvement in engine pick up speed.

I ran super-light Mini flywheels in the past - and they were lovely - but that was in the happy days when I had access to a lathe...

Here the rear view of a super superlight 1275cc Midget/Sprite flywheel in aircraft grade aluminium modified for a 7.5" clutch. You can see the deep scallop into the rear of the flywheel.[frame]

Photos of 7.5" clutch cover & 1275cc Midget/Sprite flywheel faced off and index drilled for securing screws and location lugs.
This flywheel is now used as my datum plate and is used when marking out faced off Midget/Sprite flywheels.
The 2nd photo is of the cover fitted to the flywheel. The clutch cover is a really tight fit in the bell housing and it may require some relieving of the inside of the bell housing.
Centre plate can be either Ford or BMC dependent upon gearbox used and I have used both with this set up.[frame]
