Drove an F30 with VSS. Makes the car more pointy and takes a bit of getting used to. Produces a more 'sporty'
drive.
In comparison, Servotronic produces a more 'normal' driving experience.
They are both good IMO, but different. Either one would do for me.
So, I'm perfectly happy with my lowly but linear and cheaper Servotronic rack. Have no choice, do I? I'll simply have to drive safely, normally and a bit more sedately.
