Which stock BMW flywheel is light + available for E30 325i?

[Rigmaster]

I've heard about a 13-14 lbs stock BMW flywheel, maybe on a Euro 323i (E30 or E21??). Not interested in a $300 flywheel, looking for a budget option that works.

I'm sort of in the market for one, and a friend is definitely in the market for one since he toasted his clutch at a driver's school last weekend- he wants to go with a lightened flywheel and his new clutch.


Thanks for any input.

Stock single mass 325i flywheel + machine shop + ~$90 = 11-12lb flywheel.

will this throw the balance of it off? someone told me that you cant put an aftermarket lightweight one in the E30 325i because it will throw the balance off?

Jordan nailed it. My 325eS also has a single mass flywheel, I'm planning to have it lightened soon.

whats the production date of your car, i'm trying to figure out if mine is dual mass or not.

How do you get it lightened?

Pardon my ignorance, but how does it get "lightened"? Will that affect the strength and integrity of the flywheel?

Thanks.

They are lightened by shaving off excess material. They have enough that you can shave off considerable weight without affecting it negatively.
