Mizuno ST-Z 230 Golf Driver

It took four years of rapid-fire development and worldwide tour usage to raise Mizuno metalwoods from the shadows of our iconic irons.  Now, after multiple iterative developments for stability, sound and spin, we’ve added exceptional ball speeds to our 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.

A straight bias driver with excellent stability from off-centre hits.  Similar in look and character to the previous ST-Z.  Boosted by the CORTECH Chamber to be faster from the face, spin less and deliver an incredible, solid sensation at impact.

“Tour tests for the ST-Z 230 have all been very consistent – firstly, an appreciation that the look is familiar at address.  The satisfaction at how much better it feels off the face.  Ball speeds are up on average 1-3mph with spin rates dropping around 200 rpm.”
