Hydraulic Line Variations

Please select "Stainless Braided" if you are wanting our AMS stainless braided clutch lines. This version will replace the BMW hard and rubber lines with one single braided stainless line. More reliable and stronger! Fantastic upgrade for street and track vehicles. *Commonly Selected*

Please select "Factory Lines" if you are wanting to retain the stock clutch line fittings, and rubber clutch lines.

Shifter Assembly Variations

Please select "Short Shifter" if you are wanting our AMS fabricated and assembled short shifter. Much shorter reduction in shift travel! Shifter throw and height is significantly reduced compared to the stock shifter, resulting in much more precise shifting. More reliable and stronger! Another excellent upgrade for all street and track vehicles. *Commonly Selected*

Please select "Short Shifter - Height Adjustable" if you are wanting to use our AMS height adjustable shifter. The same excellent and precise shifting our standard short shifter produces, but with a height adjustable shift lever. Capable of using "screw on" style shift knobs as well.

Please select "Factory Shifter" if you are wanting to use the stock shift assembly and bushings. Commonly referred to as the broomstick, for its excessively long throws and tall height.
