Franzino said:So how many miles/km are you already running the Eibach springs on your original Z4M shocks without issues? By the way; your black M coupe looks great...!Aliv6 said:The Eibachs are stiffer than OEM. And you will have no issues fitting them to your car. Will they wear the shocks out quicker? - Probably, but they're not expensive to replace if needs be?! And thats also an excuse to upgrade the whole lot. Put it another way, i had a issue with the left shock in mine they replaced it under warranty and never batted an eyelid at the springs?!
Can't remember....I think, about 25k stock, then fitted springs and i've run them for 10k. All good. Cheers for comment.
