6mo ago I replace my clutch to CC stage 4 and 9lbs CC fly wheel from stop to rolling on first gear when I let go the clutch I hear that s quickie noise for a second and it goes away but when im going up hill and stop when I roll hear the same s quick and also a grinding noise and I can feel it too to my clutch pedal when I'm balancing my gas and clutch rolling up hill does any one had this????

 

Its a 6 puck clutch , i guess its normal to hear and feel some grinding. And your flywheel is very lightweight so it can also make some noises.
