    Hi can you fit evo rear trailing arms to a non evo m3 and what are the difference if they are any.

    Thank you

    You can, the mounting points are the same between all e36s, as are the spring arm and rear camber control arm.

    As far as I know, the differences are the evo arm has balljoint type joints for both of the lateral arms where all others have one joint and one bush.

    As far as I know that's the only difference between 3.0 and 3.2. Probably easier just to change the bush on a non-evo arm to the evo type than to swap the whole arm over.

    Compared to a standard e36 the m3 arms have larger bearings and different caliper mounts for the larger disks.

    Balljoints? Doubt any arm has balljoints.

    ETM list same p/n for both 3.0 and 3.2.

    The joints at the back of the arm are often called ball joints because that's how they work, even is technically it's not a ball in the middle because the ends are flattened and there's a hole through the middle. Theyre pretty much an enclosed spherical bearing or rose joint.

    I.e balljoint.
