Knocking rear with KW V1 coilovers -

  • Hello!


    Have anyone experience with KW coilovers? Iam strugeling with knock and rumbling both while driving, and over bumps. Everything is fitted correct, but the noice is still there. Any ideas?

  • Maybe the exhaust pipe is knocking on the rear axis.


    Did you remove the original damp stopper on the top of the spring? The original are too long for the lower height.


    The spring can also touch itself by compression. That sounds like steel on steel.

  • This is definitely the same problem as with Koni FSD and Bilstein. The bushings of the new shocks do have a innersize of upper 10 mm and lower 12 mm, while the bolts of the original shocks do have a size of 9 mm upper and 11 mm lower, Which difference cause a knocking sound with low speeds and uneven roadsurface.


    It is a puzzle why these differences exist with Koni Bilstein and KW


    I post a thread a few days ago with the question if this problem is solved yet with Koni
