ok i had a 6-puck clutch installed and sometimes i get a groaning metal noise at low RPM take off, if i rev it a bit higher it tries to shake and chatter? Is this normal for a 6-puck still under the 500 mile break-in? Also it shifts great every other gear. Thanks

 

Fairly normal depending on the clutch. Quite a few competition clutches do that for a few thousand miles. Mine did, then after about 3k never did it again.

 

same thing with exedy 4 puck , metal noise appears sometimes after break in , it also chatters a bit...

 

good deal then, it actually only did it twice this morning on the way to work (about 5 dead still starts). So its gettin progressively better. Thanks
