Hi ///1M, I only installed my Ohlins two days ago and I haven't had a chance to take a long drive yet and its been bucketing with rain here so it's a little hard to feel how the car really handles when it's so wet. Ride quality wise, my initial impression is the increased spring rate is very noticeable. I come from a rally car background where I use shocks worth $10-15 000 with softer springs and the ohlins setup feels stiff, the car feels a little over sprung to me. Where my rally car would float and 'breathe' with the road in a damped manner the 1M is still quite unsettled on our rough country roads. But as i said, it early days for me and I still need to tune my ride heights and damping. Around town the DFV seems to improve some of that low speed jiggle that you get over small sharp ridges. Overall, I wouldn't say the ride is a great improvement over stock. It is improved in some areas but compromised in others by the stiff springs. But if the handling increases are as great as people say then I would say its a worthwhile investment. I will report back when I have a little more experience on the ohlins setup. ///T |

10 Clicks in or 20 clicks out as a starting point. There is not one correct setting, you will adjust to where the car feels the best to you.

Yes, Adjusting from full stiff seems to be the reliable way to set the shock as per the instructions. I will keep my testing within the 20 click range, I'm currently at 17 clicks from stiff. Sway bracket, interesting that there is nothing to key into the upright or align when assembling. I tried to take into account how the drop link angle would change when the car settled back down to ride height. I will have a look at ride heigh to make sure the rod ends aren't binding. Adjuster extension, would it possible for somebody to measure the distance from the nearest panel clip to the centre of the remote adjuster hole like in the attached picture? I'm currently driving without my boot liner and the rear seats are folded flat, its quite amazing to see how much deflection there is in the top bushings on the shock mount when driving along, the adjuster is bobbing up and down over every bump. I actually double checked to see if it was tightened and assembled correctly. Thanks Again |

Are you saying that 30 clicks are usable and the starting point is 10 clicks from hard? Cheers |

That will depend on where you start your adjustments, Ohlins likes to start fully closed, I like to start at fully open. 10 Clicks in is fully open and 20 clicks is from fully closed, that is where you should start for a street car. |

Obiwun,
I just measured the position of the extensions in my car relative to the clip in the photograph. Please note that I did not remove the clip so it is possible my measurements may have some error since the center of the clip doesn’t necessarily align with the exact center of the hole in the liner. 1. Using a piece of paper as a flexible “ruler” that conformed to the curve of the liner, in the vertical direction, the distance is approximately 60mm from center-to-center. I DID NOT force the template to conform to the divot around clip, just the general curve of the liner. 2. In the horizontal direction, the center of the extension hole is approximately 4mm closer to the rear of the car than the center of the panel clip. I hope that helps, John |

So my Ohlins experience so far,
I feel that the Ohlins R&T on the 1M are very stiff. I'm not sure how they feel on the E92 but I reckon they would be stiff in that application too. I have thought about getting them re-valved and possibly sourcing some softer springs but I haven't had time and I don't know which vendor in Australia would give me reasonable service. As far as settings go, my ride height is 5mm below standard ride height and have sort of settled on the following shock settings. Front 13 clicks from fully stiff Rear 22 clicks from fully stiff (I have something like 36 clicks in the rear). I have tried the rear as far as 2 clicks from fully open and I actually think it gets better. The front doesn't work so well when you take it past 15 clicks from stiff, I think it doesn't let the DFV function work properly. With the settings mentioned above I feel that I am getting the most compliant ride possible for the current setup. I do believe that the R&T has improved some elements of the 'on the limit' handling in the dry but this has compromised the on road comfort. An example where I feel a big improvement is high speed braking bumps, the car is much more settled. Basically any situation where you can put huge loads through the suspension will fell pretty good, any other time it just feels like the shock doesn't want to move. I feel the R&T is way too stiff for wet track/road conditions and even in the dry the suspension is pushing the limits of the michelin PSS. I personally would have preferred a more road oriented Road and Track setup. I felt that the OEM suspension was too stiff which is why I installed the ohlins, all the reviews I read claimed the ohlins to ride better that OE but I'm not sure this is true. I wanted to make my 1M less frenetic and more predictable by softening the suspension and letting the body move in a controlled way before the grip lets go, I'm not sure I have achieved this but it has been a fun experience playing with the ohlins and learning about my 1M. At least the shocks look cool and they do some things better than OE and they are rebuildable. I'd be interested to see how others have found their experience with the R&T's now that they have been using them for some time. Toby |

Obiwun,
My experience with the Ohlins is more positive than yours. I just came back from a 200 mile mountain road drive over rather bumpy and wet roads, and I couldn’t be happier. The car never felt unsettled and was always confidence inspiring. That said, I was probably driving at around 6-7 tenths. Maybe I would feel differently if I was pushing harder. At the moment, my car is set at 16 clicks from full stiff all the way around on the factory PS2s. My car has been lowered about 12mm from the factory ride height. I settled on 16 clicks after a lot of back-to-back testing on a particularly entertaining section of road. I could easily feel the difference between 15, 16, and 17 clicks. I have not done any testing with different settings for the front and the rear, but I am curious to test such a configuration even though I don’t feel I have anything to “fix”. I always felt the factory suspension was underdamped in rebound, which would unsettle the car. In addition, I find the Ohlins to be far more comfortable over sharp impacts. Over large motions, I feel the Ohlins are stiffer than the factory suspension, but they are never jarring and body motion is always well controlled and smooth. One thing to possibly consider would be adjusting your spring preloads. I’m far from an expert in this area, but I imagine an improper preload (high or low) would impact ride quality and consistency. I started with the recommended preload settings in Ohlins’ instructions and slightly reduced the preload for the lighter weight of the 1M versus the M3. The above said, I don’t think this is a very sensitive adjustment and a difference of a few millimeters is probably not significant. I’m also interested in learning what other 1M drivers have experienced with the Ohlins and what settings they are using. John |

Hi Obiwun,
When my Ohlins were first installed the ride was way too harsh. I recently moved to 20 clicks from full stiff all the way around, and the ride is much more comfortable. (I'm on PSS). I haven't had time to tweak it to perfection, but I'm positive you can get the Ohlins to give you the ride quality you want. |

Going to bump this thread.
Doing some serious consideration of getting some Ohlins R&T installed. According to Ohlins, there's a bespoke 1M kit available now. It differs from the M3 kit in that the rear spring rate is 110 N/mm (628 lbs) instead of 120 N/mm (685 lbs). This is presumably to compensate for a lighter car. For those of you who have installed the M3 kit, do you think that this decreased spring rate would make a substantive difference? I'm trying to get a sense of how important this would be for overall feel and driveability. (I figure the wizards at Ohlins know what's going on.) Incidentally, this would be for a combined road and 5-6 HPDEs/year scenario. |

Hi ayao,
Thanks for bringing this up, I was not aware that there is now a dedicated 1M kit. Very interesting. I have been looking at the specs on the ohlins website and it states that the spring rates are identical. I'm not sure where you got 110N/mm from? Does anyone else know if there are any differences between the M3(BMS MI40) and the 1M (BMZ MN01) kits? Have they revalved the shocks for the 1M? I have asked my local distributor but haven't had a response yet. If there is different valving for the 1M kit I might rebuild my shocks with the new valving. |

Regarding the ride height; you have the ability to go very low, I stuck with the recommended height, however, I may raise the rear. I will post some pics for those interested. I went through Adam at GMP Performance and paired the 1M R&T kit w/ a set of Ground Control street camber plates.

Side not, the instructions supplied are slightly off. You cannot use the supplied rear spacers if you use the OEM washers. I have contacted Ohlins as this sure be corrected. Plus I was missing some plastic spacers.
