when I shift some times and let off the clutch a lil fast, I sometimes hear a thud/feel it a lil bit... is that normal/I need to ease off the clutch a lil better? the car doesnt do it all the time, maybe 40 percent of the time...

 

how old is your clutch? Have you replaced your uv joints on the driveshaft?

 

You may have some play in the drivetrain somewhere.

 

clutch is 2 months old. I personally havnt touched the UV joints. but the driveshaft is an aftermarket aluminum piece
