Drivetrain Rattle

[woodsman]

Is the clutch disc a high-friction/HD/long-lasting, sprung type? Mine is and after I've been in stop and go traffic for a bit, something starts to 'hop and bang' as I'm nearing full release. I've attributed this to the high- friction, long lasting, sprung disc and high force, pressure plate. It disappears if I purposely ride the clutch. It never does it when the car's cold. I've also observed that when it's occurring, I am failing to release the clutch. Why? Because the car will catapult forward in a neck-snapping fashion or it will stall. SO what I'm missing is a little slip while 'things' synchronize to the same speeds. I have a 'Grabby clutch' because it's designed for circumstances outside of the OEM design parameters. Hence the nasty behaviour. I WAS going to turbo my car. Same problem or not?
