This weighted shift knob makes shifts faster and the extra-large globe shape encourages over-palm shifting. The Black Forest Industries Billet Knob weighs in at 8.8oz (250g), about twice as much as a stock knob and a little heaver than the BMW ZHP knob. The heavier knob amplifies the pendulum motion of the shift lever resulting in smoother and faster shift times. BFI has designed this knob for BMW and VW fitments to fit snug on the shift lever and be secured with Allen set screws. They were careful to reduce tolerances compared to universal knobs. The overall height of the BFI knob is the same as stock anatomic knobs (some BMW M/Performance models have a stock knob that is shorter than this one).

Included with the BFI Billet knob is a matching BFI crest shift emblem. A 5 or 6-speed pattern emblem is available separately.

Choose from soft alcantara or perforated air leather with either a silver or black anodized base.
