rear: 100N/mm

how soft/harsh do you think the ride will be?
higher rate means basically the amount of force to compress such spring in given distance (ie. 36N/ mm means that you need 36 Newtons of force to compress 1 mm of spring).

Higher the rate harder the ride.
Since you are basically going higher rates all around, they will give you harder ride compared to OEM.
BTW, where did you get OE spring rates? I wanted to find it but never had any source.

Are you just changing the springs or dampers also?
