I have 2 option for flywheel.

One is ALUMINIUM custom made in singapore to fit to original clutch kit.
The flywheel is 4Kg+.
Its made of aluminium.
Price of flywheel is $900US shipped to anywhere in the world.

One is Billet steel custom made from UK.
The flywheel is also 4Kg+.
Need to use customised clutch cover and clutch friction pad to work.
Does not fit original clutch kit.
However work is in process to make another billet steel flywheel to fit to original clutch kit.
Price is $1,000US shipped to anywhere in the world.

Picture on the left shows original clutch kit. In Middle is original flywheel. On Right is billet steel flywheel with customised clutch kit.
Total weight of billet steel flywheel and clutch kit on right is 7Kg. Original flywheel in middle alone is 9Kg. Original clutch kit on the left is 5Kg.


Both flywheel and clutch kit assembled.


Original 8.5 inch clutch kit. 11lbs (approximately 5Kg)


Billet Steel flywheel with customised clutch kit. 16 lbs. (About 7Kg)


For clutch kit, I have a set of unused performance clutch kit on ebay. Its abt 3 lbs lighter than original clutch kit. It can be used on aveo without any modification. Fits original flywheel and the aluminium flywheel above.
