Hey everyone, hoping you all can help me out with this. I purchased a z3 rack and mounted it in the car fine with no problems, but now I need to know what the deal with the power steering hoses is. Do all of the E30 hoses match up because for me the one from the pump to the rack is not the same. The hole on the pump side is 19 and the hole on the rack is 22. So my question basically is do all of the E30 hoses work or do I need to go scavenge some e36 hoses?

I just finished mine and ran into a little problem, but its all done now. As for the ps hoses, I first used the existing e30 lines and thought I had a problem with them, so I used a e36 pressure line thinking that would fix it, but it didn't. The culprit was the return line from the rack to the res had a small enough kink under the res that I didn't see when first installing it. So either pressure line will work but the e36 one looked cleaner installed and fit with minimal bending at the pump. The e30 presure line took some bending at the rack side which was a little harder to do. But the hoses can only fit correctly with corsponding banjo bolts into the rack, so you can't acidentally reverse them.

Never mind guys I got impatient and just took those metal bands off the dust boots, seems like they can be fastened back on.

yes it does have to be exactly centered because if it isn't then your lock to lock will not be even. You might end up with 2 complete turns to the left side and one complete turn to the right side (exaggeration), and maybe it's also that I'm pretty OCD about stuff like this. But yeah I wanted the same amount of turns to lock left and right, and I got them! :)

It will be almost a 3rd stiffer than an E30 rack. 4.0 turns lock to lock vs 2.7. think machanical advantage there's nothing more to it.
I've done a lot of research and most people choose run power steering when changing to a faster rack.Drive it hard. Maintain it well.
