Therefore my question is has anyone bought the B8 kit with the Eibach lowering springs for an E92 with M suspension mod? If so, do you have any scraping or rubbing issues?

I know tire size is a big issue as well so please let me know your tire size as well. Right now I've got 235/35s front and 275/30s in the rear. Apex rims are the recommended staggered setup of 19x8.5" and 19x9.5" respectively.

You may get some rubbing with those 275's in the back depending exactly how low you go and if you run any negative camber.

I did end up putting sport yellows on the back and stock black ones on the front it actually levelled up the car quite nicely while still lowering it some.

Awesome thread

I recently did a complete front and rear suspension refresh (except springs and sway bars) on my 2009 335i ZSP (aka S704A). I upgraded all my control arms to M3 control arms, all other pieces were OE spec.

What I am wondering about is the front ride height. The front of my car is riding slightly higher than before. I used to scrape constantly, now I don't. Granted my front struts were completely worn out before the refresh. But I can see that the gap between the tire and the wheel well is slightly more than before.

Before I ordered, I triple checked all parts. I confirmed multiple times that I was ordering, and I had ordered, the correct Bilstein replacement struts for the sport suspension.

Is it just simply that completely replacing a suspension with 140k on it would restore the original correct ride height, or is it that my suspension is riding slightly higher because of some other issue?

Honestly, I liked the visual of the slightly lower front end, and of course I don't miss the scraping. I'm just trying to determine if I should accept it as it is, or investigate the issue further.

Thank you

I have a 2007 E93 with 107K miles with M sports suspension. I am sure the shocks have never been replaced and I want to maintain the original feel as it's a daily driver. My question is should I go with the Sachs originals, Bilstein B4 or B6 or anyone know of another suitable replacement?

I would go for the B4 if you want to stay close to factory ride.

B6, in my experience, I'd quite harsh at low speeds, much better at highway speeds.
