EDIT: So the heavy duty rear shock mount is not really needed?
No problem! The only thing I missed after reviewing is the rear shock lower mount nut. I couldn't find a PN but I didn't really look all that hard...

The heavy duty mount isn't worth it IMO. I run OEM mounts with reinforcement plates and have no problems on MN roads.

I know I'll have to get it all realigned when I am done...
It's a PITA no matter what you do. The lift will obviously be easier but it's not impossible to do it with jack stands.

Do the rears shocks yourself, and have an indy do the front struts if you want to save a buck.

I found the fronts almost as easy as the rears, almost. Just rent a spring compressor from AutoZone. I forgot if the rental was free or just really cheap, either way it won't break the bank.

I'm still not certain why you guys are bashing H&R coilovers for the street. I live in Michigan and its fine... I mean sure its a little stiff but nothing that will be a deal breaker at all. That being said, I look forward to moving to Arizona in December.

I have H&R coilovers on my Porsche 911... (It came with them when I bought it.) They are WAY stiff... Great for the track but not a daily driver.

I likes my conforts!

Sam,

Thanks again for your help on this.

I finally have all the parts ordered. A fellow fanatic was selling off some new Koni Sports so I picked them up... Eibach springs from Amazon, of all places and the rest of the parts from above.

What else am I missing? Anything? I am looking to try to have this done as well as getting some CSL reps before Bimmerfest.

I read somewhere that I might need new "sport" bumpstops but I read it has been verified by Koni that the OEMs will work fine.

Anyone? Kubica? Sam?

Call Eibach and koni and ask them. Eibach has EXCELLENT phone support.
I usually call them for spring rates.

Are you sure that the Koni Sports you bought are for the Xi? If not, they won't work. Ditto for the springs.

Also, I made my own "sport" bumpstops by cutting half an inch to an inch off of the ones that were on there already. Don't buy new "sport" ones, that's a ripoff.

Isn't that what Koni "hints" you do? I think when I was looking up suspension stuff that's what I came across.

Its still a good idea to put on new bumpstops regardless. They're cheap and the foam is pretty ragged by now....

Probably, that's what everyone does. To be honest, I didn't even know they made such a thing as sport bumpstops.

Mine was fine but replace if you want to.

Yup... They are correct according to all the sites I have seen. I am having the springs, struts and shocks installed next Tuesday morning. I just got in my VB3s today so hopefully I will have everything on there by next weekend!

EDIT: I assume that if I want the comfort of a daily driver I should adjust these to full soft.

Thoughts?

After a little reading... I adjusted the rears to 1/2 turn from soft and the fronts 3/4 turn from soft. I guess I can always adjust the fronts while they are on the car... The rears I would have to remove to adjust.

Okay... I just had the Eibach 2089.140 Pro-Kit Performance Spring Kit and Koni Sport Shocks and Struts. I have heard that the springs take a while to lower to their final height but my first measurements have me a little baffled.

The rears are an inch lower while the fronts are still about the same... Maybe around 1/4" lower.

How long will it take the fronts to settle? This is pissing me off!

EDIT:

I just read this on another forum... Interesting...

I know for a fact that Eibach stress relieves their springs. The only way they will change is if their YIELD STRENGTH is exceeded, and that is not physically possible because Eibach designs their springs such that they can be fully compressed (coil bind) and the forces on the spring will not come close to YIELD. Not physically possible, period.

That said, the most common cause of "settling" complaints on aftermarket suspension is from the installer tightening the pivot point bolts while the vehicle is in the air (hoist or jack stands) with the suspension in full droop. When the vehicle is then put on the ground, the bushings are pre-loaded and a false height is the result. The bushings relax over time leading to the conclusion that the springs "settled".


A competent installer will always do the final bolt tightening when the vehicle is on the ground at ride height.

FYI: I was chief engineer at Rancho suspension for 12 years...trust me on this.
