850R rear shocks nivomats should i change?

[bonnietiler]

Been working on the rear calipers today and the nearside rear Nivomat gaiter is shot to pieces, uncertain if the shock has been affected, but an MOT is unlikely.
Can anybody explain the difference between Nivomats and others...are they better...should I find another or better to buy in pairs?
Are other shocks better suited to the 850R?
Also is it an easy remove and replace?
Thanks all in advance

Nivos are a good shock if you want standard spec and carry weight as they self level, replacing is easy enough with standard T5 or aftermarket setup, but you will need to replace top mounts too, (possibly springs)

Is there a particular version of the Nivomat for the 850R I've seen a set in the USA but they are listed for the V70 and look kinda "chubbier" in comparison?
