If you guys with painful left knees and Mazda boxes and haven't done it already, its certainly worth considering reaching down and un-clipping the tang on the clutch returns spring. I did mine not long after getting the car. I found the longer journies quite uncomfortable but rarely notice it now. It certainly worked for my knee.
Thanks for that Rog, So what's the point of the return spring if you can just remove it? Does the clutch return by itself and if so why the spring? Does it change the feel of the clutch bite etc. Forgive my naïve questions, not something I've ever really thought about let alone investigated.
Good question John. Morgan have used the same clutch return spring for years across many gearbox types, which makes me think it hasn't been reviewed for a while...
On my car with the spring removed I still have a clutch petal with a very snappy return and the 'bite' is the same so am personally happy that the thrust bearing is where it should be.
As said, something to consider or perhaps try for a while if it makes driving easier.
