Just my own opinion but I think the adjustment of the brake pedal is the most critical. The throttle pedal can be adjusted a little bit but you have to ensure you’re not compromising throttle travel with respect to too little or too much. This is especially important on a 3.2/Carrera that has a full throttle microswitch on the throttle body.
The G50 clutch really has no adjustment. Here’s why:
The master cylinder installed length is supposed to be dead on at 158mm plus or minus 1mm. So there no adjustment to be had there.
The pedal travel is supposed to be 150mm plus or minus 10mm. You can only adjust the pedal at the depressed/clutch-in end via the pedal stop that is mounted in the floorboard. That stop is intended to set your travel amount and also not to over-extend the clutch master cylinder
The last adjustment area is a small eccentric linkage that is present for the purpose of ensuring preloading the assist spring in the pedal assembly. My understanding is that it’s only to be adjusted here if the pedal assembly has some slop in it due to wear. So you can use this linkage adjustment to fix a pedal that doesn’t fully return. Otherwise the only other function of this eccentric linkage is to modify pedal effort. Either adjustment of the eccentric linkage is VERY fine- one (1) to two (2) mm maximum. So there’s nothing to be had there
Lastly, the factory manual says clutch pedal vs brake pedal height should be addressed via the brake pedal adjustment (page 46-8).
So take all that for whatever it’s worth. I would not recommend messing with the G50 clutch pedal. There’s really no adjustment in it. Many years ago I messed with the eccentric linkage adjustment and I found it made things worse. So I put it back where it was originally and decided the G50 pedal is going to be where it is (I was hoping for a lower clutch engagement point, since the clutch engages VERY high in the pedal travel) whether I like it or not
