Mizuno ST-Z 230 Driver Review

We haven’t heard a lot from Mizuno lately regarding drivers.  But that changed when the company released their ST-Z 230 driver earlier this year. 

This driver features some really cool new tech that’s designed to take your driving to the next level. 

If you’re looking for a driver that’s going to spin less and give you more control from the tee, without sacrificing distance, stay with me.  This driver might be just what you’re looking for.

Key Features

• CORETECH Chamber reduces stress on the clubface and gives golfers faster ball speeds.
• Forged SAT 2041 Beta Titanium clubface increases energy transfer between the club and ball at impact for explosive distance.
• Unified composite sole plate allows weight to be distributed to the club’s perimeter for added stability.

Who Should Buy the Mizuno ST-Z 230 Driver?

The Mizuno ST-Z 230 driver is designed with the experienced to advanced golfer in mind.  It features aid in spin reduction and control more than they do forgiveness.

If you’re a higher handicap or struggle to hit your driver on the sweet spot consistently, the ST-Z 230 might not be the best choice for your game.

Design and Technology

The ST-Z 230 story starts with Mizuno’s CORETECH Chamber.  This chamber’s TPU material increases face flexion at impact.  This not only reduces stress on the face, it also enhances ball-to-clubface energy transfer for explosive ball speeds. 

Auditorily, the same material reduced audio frequencies for a sound that’s neither too tinny nor too muffled.  Not to mention the feel is extremely stable and solid.

The CORETECH Chamber’s stainless steel three-gram weight is strategically placed to reduce spin and therefore shot curvature. 

The CG is located deeper in the clubhead, and its overall distance is shorter than other drivers on the market.  This increases shot shaping capabilities in both directions while also increasing MOI and reducing spin.  It doesn’t get much better than that. 

Whereas a lot of drivers have a sole that’s pieced together with different materials, the ST-Z 230’s sole is a single composite piece.  This design feature allows weight to be pushed to the club’s perimeter where it aids in stability. 

Speaking of mass, it’s distributed equally throughout the entire clubhead.  This reduces torque and face rotation through the hitting area.  The end result is drives that fly remarkably straight. 

Lastly, the Quick Switch hosel allows for four degrees of adjustability. 

As you can see, the ST-Z 230 is packed with tech and design features designed to help better players reduce spin and gain control for more consistent drives.

Our Experience

I knew the Mizuno ST-Z 230 was going to be a lot of golf club for me before I tested it.

With that said, I was really impressed by the low spin numbers it delivered.  My shot dispersion was much tighter than it was with other drivers I tested. 

I was also really impressed with this driver’s stability and solid sound and feel.

PROS

• CORETECH Chamber reduces stress on the clubface while also increasing balls speeds.
• Plethora of shaft options give golfers plenty of choices.
• Balanced weight distribution promotes straighter ball flights.

CONS

• May not be the best driver for golfers looking for maximum forgiveness.
• May not be the best driver for golfers that struggle getting the ball in the air.
• Shipping times can vary, especially if a shaft upgrade is requested.

Conclusion

Mizuno has long been heralded for their world-class irons.  With that said, the 2024 release of the ST-Z 230 driver has the golf world buzzing.

If you’re in search of a driver that’s stable, reduces spin, and gives you plenty of workability, the STZ-230 just might be it.
