I know I have an E36, but still....
I love my flywheel, an 11.5# UUC Flywheel with E34M5 clutch and E36M3 pressure plate.
It makes quite a bit of noise (rattles at idle; worse with a/c on), and makes some noise when you are coasting with the clutch engaged.
But it revs so much better, and just feels so right. lose that heavy dual mass junk, and get a single mass lightweight! One of the best mods you can do.
