Thanks - I thought I was losing my mind for a moment there.
Any experience with those parts? I don't think my little 964 will ever put out such torque as to benefit from greater clamping force than it already has. Or, at least, the cost of modifying the engine to reach that level of torque would make a GT3RS pressure plate a drop in the bucket. But the GT3RS part seems to cost the same or even a few dollars less than the 964 Cup part, so unless we're talking about the pedal effort difference being enough to make my left leg disproportionately hefty, I could just as well go with the upgraded one.
That's the problem with these cars. There are too many possibilities for anyone to have tried them all. Except maybe Bill Verburg. Thanks again for weighing in on this one, Bill.
