I'm wondering if I even need that klunky old termite pedal board if I am going to a hydraulic CMC, and drive by wire technique??

I'm guessing the travel on the CMC would be similar to how the brake pedal travels, and would not need that clutch stop bracket, as one does with the cable anymore. I certainly won't need that stop for the foot feed.

What is CMC?

Clutch Master Cylinder, for the Boxster trans to operate the slave cylinder instead of a cable.

The carpet is cut to fit that board. Your adjustable accelerator stop is on that board also. The stock pedal will give you a little over 1" travel which is plenty for that Wilwood.

Sounds like I would need it for the carpet only. DBW won't need the accelerator stop then.
