If the pedal is too hard, you want to reduce the diameter of the master cylinder, not to increase it.
Good job with the clutch line, it looks nice.

I considered the 0.625 mc but thought that was quite a jump. Nevertheless it looks like the next available option.

My car uses a 0.7 cylinder and the clutch feels just right. I do have an larger diameter hose going between the two. Not sure if this makes any difference but when I had it made up be furore he suggested a larger diameter

I remember skov having a stiff clutch problem as well.

That's interesting, I'll fire a message to furore for advice. I've used a -3 hose and m10 banjo fittings. All the moving parts are friction free so it's definitely a hydraulic issue.

the banjo fittings may be your issue, try a bit copper pipe in with standard male ends before you go spending any cash.
some master cylinder to slave setups do use 10mm pipe but not on the mx5

I don't know what the standard ones dia is but that is what I am using and clutch feels fine, and I am using a flexi line as well

I don't know the pedal box dimensions/pedal leverage but it's all as per the Saturn plans using a 0.7 mc.
