dropped it off and am waiting.
they have also been tasked with investigating a very loud knocking noise coming from both of the upper front strut areas. to say I am disappointed with Ohlins would be an understatement...

Ah sorry to hear that. Are they fitted to standard top mounts? Some Ohlins dampers do seem to make knocking noises, mine were making a loud clunking noise and I've taken them off and sent them back under warranty.

Then I started to get the knocking sounds after a couple hundred miles... were yours also clunking at low speed over uneven pavements or with the wheels turned? Mine also clunk when braking hard on track. I suspect it might have got to do something with the spacer that's there between the Ohlins spring and the OEM top mount. Told the lads at the shop to ring me as soon as they know more which should be today or tomorrow.

For owners complaining about the knocking noise at slow speeds etc there is a thread on this forum that identified there was an issue with the internal sleeve where ohlins altered the design. Many owners sent the dampers back to ohlins and the old style sleeves were fitted. Problem solved.

springs 80 N/mm & 160 N/mm - I can totally recommend and would even suggest Ohlins to use as their standard fit. They have taken the edge off, so to speak. Still a very firm ride, but it's bearable now which it was not with the 90/190. Car was fine, no noises, for a few miles... and then I started getting some creaking noises and the infamous metal clunk. Went back in there and found out the lower bearing that's part of the OEM top mount is shot, creating resistance and preventing the Ohlins spring from turning up top. When it finally lets loose, it clunks. So getting new top mounts and going there again, for the third time. Not happy, could've done them the last time, but it is what it is. To reiterate, this is an F80 on stock 18s.

What setting do your run your dampers on? I think I found front 12 rear 14 was as soft as I could go without undulations being uncomfortable at speed. Stark contrast to get the M Performance coilovers to feel like the Ohlins I have to run them really stiff, and the still seem pretty road compliant but if i track they might be too soft. Its a tough one, got a couple of weeks to decide what to do. |

Hey guys, so I'm tempted to refit my Ohlins, however im thinking of going from 90/190 to 90/160 or even 90/140.
Just wondering people who have done this, how did it feel after changing the springs, both for compliance and handling. Can you make good progress over a bad road without getting bucked around alot? |

The V3 rates are wrong for M2 Comp. Front: 47 N/mm Rear: 120 N/mm + 20 N/mm helper spring You can run a max 30NM stiffer spring front and rear Above info from KW. Trying to get the M Performance rates but its proving hard. I don't think they will be as hard as stated on this thread. |
