ST-Z 230 Driver

STRAIGHT, STABLE AND LOW SPINNING

A straight bias driver with great stability on 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.

Through slot provides additional CORAREA by providing sole flex

TPU material allows sole flexure for face stress reduction

TPU material provides sound tuning/damping for enhanced solid feel

Inserted Stainless steel weight, ideally located for spin reduction

ST-Z 230 Tech

Mizuno’s CORTECH Chamber encases a 3 gram stainless steel weight with elastomeric TPU – taking stress from the clubface and creating an additional source of energy.

Balanced Composite for neutral weight distribution

ST-Z 230 Tech

Design focus is a combination of deeper CG and shorter CG distance for a balance of workability in both directions while providing higher MOI and mid/low spin.

“Tour tests for the ST 230 SERIES have all been very consistent – relief that the look is similar at address. Then shock at how much better the new ST-Z 230 feels off the face. Ball speeds are up on average 2-5mph with a drop in back spin of around 200 rpm.”

Driver features

Mizuno’s CORTECH Chamber encases a dense 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.

Forged SAT 2041 Beta Ti Face

More resilient than commonly used 6-4 Ti, with more complex multi-thickness design – made possible by Mizuno’s CORTECH Chamber.

Unified Sole Composite

Carbon sole plate now a single piece to allow weight to be pushed to the extremes for overall stability.

Straight flight bias

Mass spread evenly to encourage a highly stable, straight ball flight.

Modern Players Profile

Pushed lower to the ground for low / mid spin performance and aligns square to open.

Quick Switch Hosel

4 degrees of adjustability.
