I want to replace my ball type gear knob with a weighted preferably ZHP M sport type. I've contacted BMW who say these don't fit my car. Have other members fitted a ZHP gear knob to there pre facelift e85 3.0i if so could you give me some details and if possible a part number. Failing that what other weighted gear knobs are there available. Would this fit my Z4
. Thank you.
