    Are M3 and 335i bushings and differential mounts the same?

    Hello,


    I know that the OEM E92 M3 bushings for the subframe as well as the differential mount is compatible with the E92 335i.


    My question is, after looking on Turner's site and browsing the forums, I noticed that Turner does indeed make TWO different versions of the same parts, one for E92 M3, one for E92 335i.

    Turner Parts:


    M3 Specific:



    Delrin Differential Bushings:

    Delrin Subframe Bushings:



    https://www.turnermotorsport.com/p-1...e82-1m-e9x-m3/

    335i Specific:


    Delrin Differential Bushings:



    https://www.turnermotorsport.com/p-1...2-e9x-f22-f3x/

    Delrin Subframe Bushings:



    https://www.turnermotorsport.com/p-1...minum-e82-e9x/


    My question is simply, what are the differences between these the M3 and 335i kits?


    I plan to do a M3-bits conversion for my 335i, and I want the best M3 fitting parts, so which ones are correct?


    If the OEM M3 and 335i bushings are the same size, how come Turner made two different kits?

    I'm 90% sure that the subframe bushings are the same, two front diff bushings are the same but the rear diff bushing is different.

    When I say bushings are the same I mean the same size. M3 subframe bushings are different (but interchangeable) with 335i ones.

    Thanks Nugs!

    What I ended up doing was M3-specific Turner Delrin Subframe Bushings (they said the only difference is height), and 335i-specific Turner Delrin Differential Bushings, as these are actually different sizes, as you mentioned.

    Why did you go for the M3 rear subframe bushings?

    Turner engineer that designed the bushings mentioned that it would help with anti-squat and suggested it.

    As long as it fits, I don't mind trying it out on the 335i.
