Well I have a king cobra clutch, it has been in my car for awile and I beleive it is slipping. When we replaced the clutch it was on a Sunday and no machine shops were open to resurface the flywheel, I also needed the car that Monday, so we didnt get the flywheel resurfaced. My throwout bearing is squeeling. Sometimes when I go to take off there is a terrible thumping noise that comes from the firewall area, and I can feel it in my clutch pedal. Also sometimes I will be driving already in gear not using the clutch and the cluth pedal will start bouncing and making that thump noise. I can make it stop by sticking my foot under the clutch pedal and pulling back on it. I am thinking about getting my flywheel resurfaced and continue using my existing clutch. I have an 11" flywheel that came on my 04 motor, so I am thinking about using the 11" flywheel and buying a new clutch. Any suggestions? If I should buy a new clutch any particular brands, that are 11 inch? Thanks
