You need to raise your rpms... Your clutch is aggressive... I had a stage 2, 4 puck unsprung and it used to shake when leaving from a dead stop... And the clutch also went out 2 months later so it might need to be replaced soon. And while your there just spend the extra $ and replace EVERYTHING so you don't have to pay someone to take it out again...
Meaning get a full clutch kit and flywheel.. NEW flywheel not just resurfaced

and you should look on ebay for it and have someone put it in if you cant

i have one in my car from them... lifetime warranty
