Car shakes or shudders on clutch engagement

[blkbb6]

the lude shakes or shudders very hard before clutch engages, all motor mounts are good... this a new clutch with approx 100 miles, it was fine until a few days ago, once the clutch engages and gear shifts everything's its good, the shake only happens on low rpm engagement, when i rev up to about 4k to 5k to take off it the car doesn't shake... its a stage 4 xtd clutch kit (un-sprung disc) and used fidanza flywheel with new friction surface, if your going to come bash on the product don't waist your time on this thread, thanks in advance...

With an unsprung clutch there is no feathering of the clutch in... It will kill the clutch. Those type of clutches are basically drop and go. Not meant for comfort or ease of use.

I think its normal for the set up you have to shake at low RPMs. I have a clutch masters stage 4 and it does the same ****. Basically when you shift at a low rpm its going to vibrate. I hope you have a turbo set up, or running atleast enough power for it.

Even my sprung 6-puck shudders at low RPM, backing out of my driveway is a bit of a chore ... this could be because the springs aren't fully broke in though too.

These clutches are intended to be dumped in the burnout box and at the starting line, not DD'd. If you insist on using one, get used to it.

my buddy had a mustang and replaced the clutch but didn't get the flywheel resurfaced, and every time he put the clutch in the entire car would shake.
if it is a new or resurfaced flywheel then its probably from having the upgraded clutch
