Hello guys!

I need to hear some opinions and some wise words from you..

As you can sense, i got myself stage 2 cerametalic clutch from exedy, and it was exchanged few days ago (170 miles now). The old clutch was going deader and deader so i had to do something about it. Also i wanted to change the engine and the transmition mounts, because they needed it too. ( i am second owner of the car, 85k up to this moment, i took it from 74k)
So, got exedy stage 2 and also got my hands on Cusco engine & tranny mounts + sti "dog bone". Long story short - new clutch is in, so are the dog bone and the tranny mounts (the service didn't put the engine's on, needed more time and s%@# so i told them to leave it (planning to do it by myself in less than a week time), also the flywheel is turned/re-surfaced..
Using the car now, but there is a lot of shuddering going on (little less now, but it was really nervous the first 2 days..). I do know (didn't at first place, but then dig my head and got the information) that the Cusco mounts are really good for making the car talking to you.. Significant increase in noise and vibrations inside is always good for informations gathering purposes..
Anyway, i know that Subaru got some issues with clutch shaddering, stock and aftermarket..and the transmition issues... I just need to know how much really is normal?(!) I saw a lot of posts about the issue (to be honest, they make very depressing reading..) but also there were big bunch of you that have some experience with the Exedy.. So, give me a hint, is it normal?
Additional information about some proper brake in-ing of the new clutch would be greatly appreciated :}

Thanks in advance!

p.s - forgot to mention -> the car is stock, no power or drivetrain upgrades (until the mounts, now) . Also it is my first experience with brand new clutch (the choice for the Exedy was with look in the future, when i would be puttin some money in the car, but it had to be done anyway, so that's why it is in..)
