Mizuno ST-Z 230 Golf Driver
Faster Ball Speeds With CORTECH Chamber

The Mizuno ST-Z 230 Golf Driver is a straight bias driver with excellent stability from off centre hits. Boosted by the CORTECH Chamber ST-Z 230 is designed to be faster from the face, spin less and deliver an incredible, solid sensation at impact.

It took four years of rapid-fire development and worldwide tour usage to raise Mizuno metalwoods from the shadows of their iconic irons. Now, after multiple developments for stability, sound and spin, Mizuno have added exceptional ball speeds to their performance equation. Introducing the CORTECH Chamber. Mizuno's CORTECH Chamber encases a stainless-steel weight with elastomeric TPU - taking stress from the clubface and creating an additional energy source. At the same time locating weight closer to the clubface to reduce spin rates. While contributing to a more solid, powerful sensation at impact.

The forged SAT 2041 Beta Ti face is more resilient than commonly used 6-4 Ti, with more complex multi-thickness design - made possible by Mizuno's CORTECH Chamber. A Unified Sole Composite consists of a carbon sole plate now a single piece to allow weight to be pushed to the extremes for overall stability.

Built for the modern players profile the ST-Z 230 is pushed lower to the ground for low/mid spin performance. Mass is spread evenly to encourage a highly stable, straight ball flight while a Quick Switch Hosel provides up to 4 degrees of adjustability.
