So I am in the process of replacing ALL the suspension components on my newly acquired 91 E34 M5 (build date 09/90), and surprisingly, everything was original at 110k miles, bad shape, but all came off very easily without any sign of seizure or difficulties.

Three remaining issues before I put them all back:

1. How do I adjust the rear Koni Sports?, can I still adjust after I put them all together? the fronts were Dinan, so I know I can still adjust after it's all in, so I am not worried. But the rear is different, does not have the adjustment in the middle of the rod. Instruction says you need to compress the shock, then turn, so I suppose it must be disassembled every time one wants to adjust? If so, what's the stock Dinan setting?

2. In putting the rear together, I was unable to put the spacer back (plastic piece - see picture). In fact, without the spacer, the spring already does not need to be compressed at all. Something tells me the shock is longer than the OE hydraulic shock. I compared the Dinan spring with OEM, didn't notice a big difference... I suppose it's OK when I put it back, the weight of the car will keep it compressed, but something doesn't "smell" right.

Any ideas?

3. if I want to replace center tie rod and idler arm, I suppose I need to remove the shield - any instructions on this shield? looks very different from my E34 525 (separate topic for separate post)

Thanks in advance

usually dinan ships their shocks/struts adjusted to their specs. You are correct in that once you install the rears, you're not adjusting them again. I'd call them to confirm that they're preadjusted.

I got the front Dinan Konis from a board member, and the rears were off the shelf Koni. I want to confirm what setting so I can put them in correctly. Do you know how to adj rears?

Also, doesn't seem right that I don't even need spring compressor to assembly the rears, right?

Here's the photo of the "spacer" I was talking about. Also see all my NEW stuff...

I have almost all the same new parts. I bought Koni and eibach springs. Just finished putting the front in and am starting the rear tommorow. My plan for adjustment after reading some post on here is to set the rear one turn from the stiffest.

Have you finished the front yet? I found that the koni dampener was almost an inch shorter than the stock unit. I thought the ride hight was only going to be 1/2 inch lower. I took some before ride hight pictures and will take some after for comparison once I get the car back on the ground.

Have you figured out how you are going to run the PAS fluid loop?

Mine would be back together if I had a new bump stop mine is toast.

To adjust the rear for a sport type ride, get an allen key that fits on the top of the shaft. Fully compress the strut and turn the shaft clock wise until it stops (Around three turns) Then back of 1 full turn. Now you are ready for assembly.

My springs will need the spring compressor for reinstall. How are you going to attach the dust cover to the bottom of the strut? I will try and zip tie it but the cover is way to big.

This sls delete is not going to be easy. I cut the small diameter steel lines that go all the way to the rear long at the suction and discharge of the pump and will try and make some fitting to join them together. I hope I did not cut the brake line by mistake!!!!!
