    Spacer Dimensions for Z3 rack swap

    Hey guys,

    Anyone know the dimensions for the spacers used for the z3 rack swap? I've done some searching and can only seem to find "buy this spacer and cut it in half." I'd rather just get/make my own that are the right size instead of doing that.

    Thanks

    Well went ahead and made my own spacers this weekend and got the Z3 rack installed...What a difference. For those who are interested, here are the dimensions I used for the spacers (all made out of aluminum).

    Rack Spacers: 1 or 1.5" OD w/ 0.400" through hole, 0.535" thick
    Steering coupler: First off I used 3/8" bolts so the holes in the steering coupler need to be drilled out with a 3/8" bit.

    Sleeves for where the plastic bushings are: 0.55"OD x 3/8" ID 0.40" tall. When I was making these I just kept slipping the steering coupler on to make sure it had a nice slip fit.

    Spacers: 5/8" tall w/ 3/8" through hole.

      First thank you for positng this ice been reading through the long post and all I got was the e36 rack spacers were too short for the z3 rack.

      Second I'm sorry for reviving your old post. I'm confused I thought it was 2 sets of spacers. What is the bottom one for?

      From what I understood rack spacer = the one that goes under the rack where it mounts to the sub frame?

      Sleeves are for shortening the coupler?

      5/8 by 3/8 spacer? No idea what did I miss?

          That's for under the rack? Or over which did you do? Seems everyone thinks one is better than the other at reducing bump steer /_\ there is way too much info about this topic but nothing specific to one rack or the other

          I've decided to try deleting the guibido (or however it's spelled) completely instead of cutting and adding spacers to the coupler something about keeping the ability to move sounded good
