Just install Exedy ll with Exedy(Daikn) lightweight flywheel on LE5 2.4. I did not remove a dual mass flywheel from the 2.4 but a single mass. The whole package was 15 lbs lighter with a slightly less mass and near floor engagement it's easy to drive but can easily be stalled.
The pressure plate and clutch were coated with machining oil. I had to use a rag with brake cleaning solution to get the black off. This step might help with chatter when first starting as mine was quiet.
It's one man job if you have a transmission jack and minus 20 years SOB's senior.

but expect a workout and a broken clutch line if your not careful.
I was grinding gears for the first 100 miles as I replaced a bent clutch line and self bleeding took forever.
Where before the stock mass flywheel would slow the engine and boost(Hahn turbo) would get a jump and give you a lung, it's more seamless now watch the speedo zip up.
Thanks for the feedback! This is something I really need to do (clutch at least) but I really wish I could drive an LE5 without the dual-mass to see the complaints.
OTOH, I thought the whole point was faster spooling of the rotating bits with the weight savings....ie, quicker response. What about it benefits track cars? Less weight, less wear and tear?
