Ohlins R/T clunking after install
Hey everyone,
Recently purchased Ohlins R/T with Vorschlag camber plates from one of the forum members. After install I noticed they would clunk while going under 10mph over any bump in the road (minor or major). I went back to the shop to have them double check their work, we made sure everything was tightened to spec and installed correctly, all was good, but still the clunking is present. At our last ditch effort to isolate the issue we noticed where the top of the spring meets the camber plate the diameter seems to be a bit off which allows play in the spring. I am wondering if these are the incorrect camber plates for the ohlins R/T, however I have been in contact with the previous owner and he claims he experienced no clunking or any issues with the setup. Any input/insight is greatly appreciated. -yes the 3 strut mount bolts are tight. -yes the top nut (on top of pillow ball is tight) -I am on oem end links but they were fine before install. -yes the preload is set high enough for that to not be the cause. Thanks in advance, |

I have to say I may be experiencing the same issue after my Ohlins upgrade as well. Ohlins RT + Ground Control Camber plates is my setup.
About 5-600 miles after install there were no issues or sounds of any kind. As of last weekend(~700 mikes) I began hearing what sounds like clunking or rattling coming from the rear or the vehicle when driving at low speeds over road bumps. At higher speeds the sound can be heard if you listen for it but it's faint due to road noise and engine noise. I'll be taking my E92 to a new mechanic this weekend to investigate the issue. The GC kit was purchased for OEM spring size as advised by GC customer service at the time of ordering. The car has not been driven hard since the install; just your normal driving to/from work. It appears to be getting more noticeable and more frequent but who knows- I'm not an expert. |

OP, tell your mechanic to remove vorshlag plates and inspect spherical joints for play.
They go bad from time to time and need to be replaced. Loose joints cause clunking noise you describe.

Do you have an EDC equipped car?
The install manual for Ohlins was a little unclear and I recall my original mechanic was unsure as well. The rear install manual showed 2 possible assembly guides- one for EDC model and one for Standard model. The difference was the use of a spacer they provided. Im dropping the car off in a few hours and will post back what the new mechanic tells me today. Luckily I still have all my original suspension parts that came off during the install. The clucking I hear appears to come the rear but I'm not entirely sure. |

Tighten the upper nut/ check preload(If you can spin the spring by hand easily, that's the problem), problem will be gone 100%

Mechanic reviewed my entire setup and found the wrong washers had been used in the rear. Using the correct hardware that came in the bag and the clunking is now gone.
Have your mechanic check and re-check that all the correct hardware is used for the install |

Here's another link with even more detailed pics. One pic mentions to trim the center of the isolator.

Do you have pics of the washers needed for edc cars? My rear started to knock really badly, but I got my ohlins used so I don't know if the washers and spacers are there.

Install Manual: https://www.ohlins.com/app/uploads/w...MI_BMSMI40.pdf Go to page 6 and compare the two install options. Notice the additional washer and spacer for cars that came with EDC from factory. The guys at Ohlins are very helpful and can probably hook you up with a bag of hardware for a few dollars. Then just revisit your mechanic and fix it up Hope this helps. |
