Looking for a lightweight flywheel that fits the Si...

 

Give it time, I dont think there is any out for the z3 yet. Ill look into it though.

EDIT: Ive seen that the z3 flange is the same as the past K's. Can someone verify?

 

Comptech has one, but it requires you to replace the entire clutch assemble, which I am guessing you would want to do anyway.

Weight = 9.5 pounds $349.00

Fore the new Clutch Assembly add another $438.00

So, this is the only one I have found.

 

you should be able to use any JDM DC5 flywheel and clutch assy. I believe they are the same.

 

So you need to use both the comptech flywheel and clutch assembly...
