Going back to suspension for a moment, I also feel there are other dampers which would work as well. Each marque has their own favourites, but most will do the job. I have the Nitrons as I bought my car pre-specced for a small saving, so am quite happy. Whilst touring to Laon and on to the Black forest in June, fully loaded, I did occasionally get a graunch from the rear, when going over speed humps and might wind the spring seats up a turn or two. I had already softend the dampers all round by one complete turn with a small but noticeable softening, when I got back I softened it by a further half a turn to fully soft, but found no difference. My feeling is that for road use I want comfort not to feel every cats eye, even when making progress. Why MMC have this idea that all their cars should be circuit hard I do not know, they are almost always driven by senior citizens who have usually done that and don't want to lose more fillings?
I was talking to Peter, late of SSL some months back and he felt that using their anti roll bar links would result in a better ride, sadly I decided to save the £200 for another day. Maybe there is something in that though?
