I have 3 STM 72AX weights for sale. Perfectly good shape. They are pretty much new. Can't have over 50mi on them.
Asking $140 shipping included to the lower 48 states.
These cam arms were specifically designed for the Z1 Turbo/Procross upgrade. This a new proven and tested design that is prefered by Z1 tuners. These arms have a large hump on the back that creates more engagement and more load when the turbo needs it. Available in a 72 gram base with the capability of adding 42 grams per arm for adjustment. This design allows the option of adding large quantity of weight to three different areas on both sides of the cam arm to create the shifting characteristics you desire. Each arm can be assembled with tungsten and steel washers that can be used in various combinations to achieve the desired operating RPM. The SUPERTIPS will fit the stock Z1/Procross primary but will require a .06 spider shim to be installed. Our tungsten washers weigh 7 grams each. There is no other arm on the market that allows this wide range of adjustment.
