Still haven't found any reviews of the FX200.
It's like no one buys it, but no one can say why. They just arbitrarily go with the FX300.
I wonder if the FX300 actually has a softer pressure plate than the FX200, and takes advantage of the decrease in surface area to improve power capacity. They remove clutch disc material to make up for the light pressure plate, and still get the same clamping force.
But, of course, that's unsubstantiated. I haven't yet found anyone who has put any miles on an FX200. And most of the FX300 reviews I've seen have fewer than 10k on them, no test-of-time in my book.
Time to call Clutch Masters.
