No, it's not the vdc. If I clutch out little smoother when I shift to second gear the car won't shake/jerk. So it's my poor skill.
Now if the ecu preventing you rev above 5k in neutral, is it bad to hit the redline in first gear? I can feel the engine starts to shake and hit its limit when I rev to 5k in first gear. Is it normal? I see plenty of peaple rev to redline in 1st gear on youtube tho. Do you guys do that too for a aggressive launch?
