I wanted to ask Doyle if there is anything special about the PSS10 coilovers or H&R Coils?
I too am like most in this section...I want a factory ride quality, but with some minor improvements. I have had cars in the past where I added a new suspension and felt like my teeth were rattling far too much.
I drive a 2011 335xi if that is any factor for comment. I also live in Canada where we receive large quantities of snow and don't want to lower too dramatically, but am a bit worried about a spring/shock combo and would 'prefer' a coilover for long term use and happiness.
