What are the spring rates of 993 M033 springs?

[Mario149]

Would like to know front and rear spring rates of the M033 (*not* the M030 sports ones) springs for a manual 993 if anyone knows? Doesn't seem to be easily googleable...

Same as standard i think
M033 is just a lowering spring.
So 145, 217

M030 is 165 285

pretty certain M033 are:

Front: 143 Lbs
Rear: 297 Lbs


and M030,

Front: 165
Rear: 285

Wouldn't that make the sports M030 softer than the standard M033?!

It would seem so on the rear at least. That can't be the right figures. M030 is supposed to feel hard and a bit crashy on our roads, hence why I went M033.
That figure for the rear must be wrong surely.

MO30 is also a progressive rate spring. Get's stiffer as it compresses.
