    Subframe and Differential Bushings Selection for Lowered 325ix

    Hey all, doing some light resto on my 325ix, and I have arrived at the rear end. Front suspension is already rebuilt. Rear subframe is ready to pull. I'll be replacing all the bushings back here. I am lowering the car on the 325ix specific H&R sport springs.

    I understand that the 325ix subframe bushings raise the car up .300" vs the standard RWD E30 subframe bushings, and that it can help with camber problems on a lowered 325ix to use the RWD bushings.

    I intend to run the car on the H&R springs for the foreseeable future and would like to choose subframe and differential bushings that will be ideal for this setup. Is it worth it to go with RWD E30 bushings, and if so, which should I go with and how do I set up the diff at the correct height? Also, is this going to make the front ride higher than the rear?

    Thanks!

    So I'm going to go with RWD subframe bushings and a RWD diff bushing, with the centered hole. What size spacers am I going to need for the diff mounting bolts? Anyone know?

      I think I finally figured this out... shouldn't need spacers with this choice of bushings, but correct me if I'm wrong.

        That's right. I would take a look at your rear shaft angle too. Make sure the slip mechanism is free and adjusted.
