I have a 97 sti that has a rattle

Here i go. 6 months ago i replaced the clutch for an exceedy organic race clutch(pink box) and had the lightened flywheel skimmed at the same time.

a day later i had it down the pod( i know i know i didnt bed in )

well since then it has a vibrating rattle when you come off the throttle. sounds like the zorst hitting the prop(it aint)

also really really juddery when pulling off or down changing.

its been to a very repuatable tuner and they have replaced the rear diff,gearbox, prop and driveshafts for p1 stuff.

yet its still there

needless to say i aint going back there

i now think it must be the clutch of flywheel.

any thoughts would be appreciated
