Heard some talk about strut top mounts/spring seats recently. I agree that genuine top mounts are probably best, but heard xc90 as an upgrade from the spring seats, but are they any better, does anyone have any real info on them being better ? As I'm just about to change the Guls suspension (not because it needs it, its just I have a nice set of Koni's on the shelf here (Thanks Neal)) and was going to change the mounts whilst I'm at it.
