Yeah on resurfaced roads/track the Eibachs out perform the standard springs easily but on uneven roads with potholes, raised iron works etc the ride is harsh. I've fitted Eibachs to my last 5 cars and think they are a great spring over standard.
Fitted Eibachs to the E89 M Sport, suspension hasn't altered much at all (10mm-15mm max), on bumpy roads the Eibachs are harder and more uncomfortable. On smooth roads they are better than the M Sport setup, worth the £120 cost to replace all 4 springs though over OEM
Sorry if posted before but what a disappointment especially when I can't keep a car standard for long.
I want a new exhaust system, more torque, rear bumper and rear wing and I'm in love with the Rowen setup, I know many of you don't like this from when I searched the forums but I think it...
I haven't taken any pics yet as only been done a week so still settling down, can see a difference though. I'm expecting a drop of about R20mm F15mm over the M-Sport springs.
We have crappy roads over here mainly, but on the ones that have been resurfaced it's a good ride, I've fitted Eibachs...
I experienced the red screen in the middle of nowhere when relying on my sat nav a few weeks ago, wouldn't come back on whatever I tried. Next morning all was good, common issue I'm led to believe with the iDrive on the Z4
Have one already, it's a 2011 2.3i Highline Edition M-Sport with red leather, black gloss 19" wheels and eibach springs at the present but am sourcing parts from USA and Japan to further mod it.
