General Maintenance & Repairs - Car rumbles/vibrates ALOT

Ok so I just got a new clutch (monster stage 3 and tick performance master cylinder) installed last week. My car vibrates/rumbles ALOT from a dead stop in 1st and reverse when I slowly release my clutch. It does this only in those 2 gears. Any clues what it could be?

probably jut chatter. Hopefully it should tone down once the clutch is broken in more.

When I mean rumble/vibrate I might as well say small earthquake
