It seems that new PSS10 has improoved coating... but maybe HR in inox is better?
Will negotiate with HR and bilstein to obtain a mixed kit with 335i front and M3 rear.
Unfortunately there is no bilstein ride control for M3
The Triple-C coating on the PSS10 is supposed to be 40% better at resisting corrosion than stainless steel. We'll see how it goes, but so far the quality has been top notch.
