Hi sifus. I don't know whether this was discussed before. I am contemplating fitting h&r springs for my 530i. I noticed that h&r has 2 types which is for sports and non-sports factory suspension. Does anyone know what is the difference?My car is not an m-sport. It had the standard stock springs. I later changed them with a used m-sport springs. I have noticed the car now tends to float when in the highway when I hit an uneven patch. Also noticed when I replaced my tyres that the right front tyre was more warn out on the outside. I am currently using boge absorbers.I hear that h&r gives a firm but comfortable ride. If this true?Appreciate all hour advice.
