Wow thought KW had stuff in the USA and that it was a well known brand , my bad.
There was always a big debate over here when I had the M3 over those 2 brands.
KONI for cheap and good shocks and springs , easy to maintain
KW for much more money but maybe better performance and they come in stainless steel.
I wanted the everyday drivers input if he felt it was worth the extra cash for the KW , but I guess everyday drivers dont care just as long as it says "not original" cause he'll never will be able to take the car to a point where he feels the diffrence.
Sorry for making this a useless thread
