M suspension - more "comfortable" or "more stiff"...?
- Thread starter polo1
- Start date
There was a z4 suspension matrix somewhere and it shows non m sport suspension is stiffer than M sport in comfort mode, that's what made me decide to just go for M sport, esp. because I like the trim more.
That being said, I'm on OEM summer run flats on 19" rims, and in cold weather < 60 degrees, even in comfort it's pretty harsh. When it's a bit warmer outside things are more comfy.
EDIT: I see the matrix 5 posts above mine now... I think pics weren't auto loading on mobile
Thanks!

Do you have M Sport suspension or Adaptive suspension? Because if it is just M sport suspension or even the non M sport standard suspension, changing the setting from comfort to sport does not alter the suspension at all.

I found drifting away from the door pillar tyre pressures really upsets the car, even if that’s pressures for 18’s, so I run those pressures after some experimenting.
Off topic slightly but do you not find 18’s and non flats too soft in comfort Buster...? Also have you ever tried 19’s for comparison on non flats..? Pure idle curiosity is all as as I said I find MPSS’s almost too soft on 19’s.

I came from a 911 on Pirelli P Zero Rosso* - the best tyres I've every known - to the 35iS on Bridgestone runflats - the worst. The runflats went in a month. At that point, I had the chance to change the 18" wheels, too, but knew that the OE 19" cracked sometimes.
I didn't believe they did because of "hard tyres", but because of poor design. So, I returned to what I knew to be good: Pirelli P Zero on 18". Both have proved to be very good, indeed.
(*The P Zero Rosso are black glue, but for Porsche only and last 10k miles at most. The P Zero are the next best thing, but last x2+.)
Coincidentally, the recommended tyre pressures for both the 911 and 35iS are F36 & R44.

Well if you’re happy on 18’s look wise why change indeed, and so you don’t find 18’s and the P Zero’s too soft then..? Having said that the only experience I have with Pirelli’s were a couple of sets on an old Escort that were downright dangerous after half worn and I’ve never gone back to them, MPSS’s are my tyre of choice, so admittedly I’ve no experience of modern Pirelli’s.
Yes, I can remember when Pirellis weren't as good as they are now. And I experimented with Michelins on the 911 and thought them very good (although not as good as P Zero Rosso*).
I suspect, however, that there isn't any significant difference between the Big Five (or is it Six?), other than the bo//ocks that car journalists talk about them. The tyre market is very tight and price is the major determinant of quality.
(*This is a useless comment, unless you have a Porsche for which the Rosso is made.)
