Re Stu's comment, "Much better than my original Bilsteins but they're 20 years old so it's actually a comparison of apples and pears, unless I have the Bilsteins refurbished any comparison is invalid". I had my 15 year old Bilsteins rebuilt a few months ago and the difference, obviously, is there to be felt when driving the car. A lot more supple and an improved 'feel' to the car.
