I put a dual friction in my wife's '90 5.0 LX 5-speed, figuring that since the cost of labor was so much and it was a job that would last years, why skimp? I also heard that it had lighter pedal pressure with superior clamping pressure. How could you go wrong with that, especially since I planned to upgrade? That was 9 years and 90,000 miles ago. It is also now 80,000 miles since I dropped in an iron head GT40 motor with an E303 cam. The only hiccup was the Ford throwout bearing going 10,000 miles ago. But the guy who pulled it saw nothing wrong with the disc, and I paid $300 to replace a $30 part only. On a cost-benefit analysis, I can't see how you could complain, despite the high initial price. The dual friction does have slightly lower pedal pressure, although not enough to make any big deal over. But the clutch has performed flawlessly in daily (as well as "spirited") street driving. Since the clutch is still working great with 90k miles, I have no comparison, but will put in another dual friction if I ever have to. And yes, my wife does smokey burnouts with ease. Now If I can only get her to do it in a bikini.
