I have always found it difficult to adjust my rear damper settings mainly due to the boot trim, some say just remove the boot trim but love everything that is oem in its place so it was always a fiddle having to move it away to adjust and play with the damper settings.
I have now found these which extends the adjustable damper setting out so the boot trim can stay where it is
