LUK Flywheel lighter than OEM??

I was always under the impression that there wasn't any difference between both flywheels, LUK and OEM, except for the branding.fficeffice" />

Yesterday I replaced my OEM flywheel with a brand new LUK flywheel and the mechanic and friend who worked on the swap told me that there was a significant difference in weight. He says the LUK flywheel is lighter!

How come I never read this anywhere before?

The OEM flywheel and clutch were ALWAYS manufactured by Luk. The aftermarket Luk part has always been 100% identical to stock. Unless Luk made a running change in design your mechanic a full decade after release of this part, your mechanic and friend are drinking some good beer. I vote for the latter, so ask them what brand.

Resolve never, screw genuine.

A running change is possible, but only likely IF:

a.) There were reports of issues or...
b.) This flywheel was used on a variety of models (or continues to be used) and Luk is trying to have one model satisfy the needs of multiple cars. This isn't uncommon with a lot of parts, but I would think this one is pretty unique in its applications.
