Pulsation in clutch pedal and rumble
 

Has anyone else experienced this and what should I be suspecting?

Had the "South Bend Stage 2 Daily 370Z Complete Clutch System – Solid Flywheel" installed, and since I have had a very noticable pulsation in the clutch pedal, feels like a foot massage. This is felt at idle and when driving. There is also a new thumpy rumble coming from near the tranny when accelerating, almost sounds like a throaty exhaust? :confused: :confused:
