"Overall great construction. The piston is elongated to correct AOE which was designed beautifully. Rack has under belly support (plastic along the bottom) which adds a layer of adhesion when using epoxy. Usually standard racks side mounts are more than enough but it’s nice to have that support as well. Teeth are holding strong so far in a 150 spring dsg. Constantly been taking it apart and I see no hairline fractures or points of failure. Definitely a step up from pistons in the past.
