I'm in the process of installing my new ACT clutch, but for the past oh, I'd say 2-3 months, when I press the pedal down, you can hear a vibration of something, like two plastic parts rubbing each other. As the pedal goes down, it's like two plastic pieces rubbing on the way down, then the squeal past each other on the way up. I've done some invesitigating, but I don't know what's up? any suggestions would be appreciated. Also, what's the price, high or low, you guys have paid for Redline MT90?
