Had the standard knob changed on my S3 when I bought the car. The Aero America (with the silly side covers and one or two other minor changes) came with a nice metallic knob and that was fitted in place of the standard one on my car although the dealer did say it was quite a lot harder to do than they had thought.
Pretty sure the S1 gearbox is different though so although the standard gear knobs look similar they may not be underneath...
Much prefer the metal knob though - much classier than the standard very dated BMW knob!
