I'll try and get a video of both the rock sound and the shuddering one of these days. I have a steel McLeod flywheel so you would think McLeod would send it good to go. But I just have to get used to it. I wanted a modified car and this is what comes with the territory.It's not going to be as smooth as a stock clutch when taking off. It's going to take a little more RPM to get moving since it's a grabby clutch.
That being said I don't get a box of rocks sound from mine even when I'm creeping along in traffic at 1000rpm. But I don't know what flywheel is in the car. That might be the difference.
