I've been getting problems changing gear now. Slowly its fine but if I'm going for it I change and it won't go in to the next gear for a short period. I've got just under 2k on the car.
Originally I suspect the thrust bearing or the syncro mesh on the box as it does have 113k on it now.
I think I've worked out why now. The whole side of the pedal box flexes when you push on it (this is by hand me looking to see what's going on. The master cylinder which should be stationary moves a good 5mm left to right and forwards a bit.
Now I suspect when I move the pedal quickly with my foot it flexes a lot more - the flex means the piston is not pushed in far enough to disengage the clutch completely.
I've got several thoughts:
1) Weld a thicker piece of metal over the clutch site with a bend to re-enforce it (may as well do the accelerator pedal as well as it floats about too when you use it)
2) Drop the clutch pedal completely from the box and use one of these:

3) Bin the whole pedal box and go for something a lot more substantial. Issues here are all the racing boxes don't have servos which means it would need one or two remote servos which makes the whole thing very expensive.
No. 1 is a good short term solution.
If there is enough room No 2 I think might be a good solution
No 3 is a bit drastic, but with the master cylinder inside the cabin it keeps the heat away from it.
