My friend had a stage three clutch masters for a while. He has a boosted b20. The car began to have problems where it would not allow you to go into gear. We took everything apart and noticed the disc was cracked where the springs are for the disc, four cracks total and one peice of metal totally came out and lodged between the disc. I gave him my stage four clutch masters with the fidanza flywheel. Now the car shifts but there is a persistent rattle that gets louder with speed. So WTF we don't know if it is from the tranny, clutch, or the axles. I know the clutch is in there torqued accurately and with loctite, I have done this several times so I am sure it is in good. Just wondering what could it be. Shift fine, but there is a slight vibration to the pedal and shifter. ????

any suggestions. this is getting frustrating.
