So I'm going to be installing a new OEM clutch to my 05 WRX and bought the exedy light weight flywheel (FF01, weighs 12.7lbs) with it.

I've been reading a lot of old posts about a light weight flywheel throwing CELs if it's under 13lbs. I'm definitely not pushing a lot of HP at all either. Car is basically stock. just need some opinions on whether to install it or not? And how much does the OEM flywheel weigh?

All I have have is a Cobb CAI and Cobb AP tune and Invidia TBE. 93oct Stage 1 map that came pre loaded with it lol.

There is more than one "OEM" flywheel; the heavier ones are considered better (Subaru issued a TSB for the bugeye cars because of clutch shudder, and the fix was a heavier flywheel). If memory serves the 12342AA071 flywheel weighs ~8kg or a bit more.

The existing threads are accurate in terms of opinions.
