I'm getting ready to do the same thing as you and have been considering the very same clutch. I called Permance Mustangs (Houston-based 65-new Stanger dealer/autobody) and they suggested that I go with the Luk clutch. I was told that has just as much clamping force as the King Cobra, and requires less pedal force. Of course, this isn't a clutch that I see in too many magazines, but I say let the research do the talking.
...its an OEM replacement. My clutch completely went out when I was in another city so I had a shop replace it. It had a Ford Motorsport clutch in it when I bought it.
After they put in the Luk clutch I drove it nice and easy to let it break in. Now I can tell you, it isn't the same as a Motorsport clutch. My car doesn't have the same gripping power it had before. Clutch pedal feel is the same to.
I don't do much spirited driving, at least not until I rebuild my grinding T5. But I am sure if I did, this clutch would get roasted pretty quick. I would get something else.
