I have a Cube Acid with the above fork. The spring is far too stiff for a rider of my size (9.5 stone) and I want to change it for a softer option.

The Rock Shox Manual shows a couple of options and I'm pretty confident all I need is :

13 11.4015.041.000 Dart Spring/Spacer Kit Soft (Black)

Do I need to swap out any other parts or is that it?

Help appreciate. Thanks.
