Mizuno Driver ST-Z 230

Mizuno Driver ST-Z 230

• Straight, stable and with low spin

  • A driver with a straight bias and excellent stability on off-centre hits.
  • Similar in appearance and character to the previous ST-Z.
  • Thanks to the CORTECH Chamber, it is faster from the face, has less spin and an incredible, solid feel at impact.

• Tour Tests

  • The tour tests for the ST-Z 230 were very consistent.
  • Initially an appreciation that the appearance is familiar.
  • Satisfaction with how much better it feels from the face.
  • Ball speeds have increased on average by 1-3 mph, while spin rates have decreased by about 200 rpm.

• CORTECH Chamber - The missing piece

  • Mizuno's CORTECH Chamber encases a dense stainless steel weight with elastomeric TPU.
  • It takes the stress off the face and creates an additional energy source.
  • At the same time, the weight is shifted closer to the face to reduce spin rates.
  • Contributes to a more solid, powerful feel at impact.

• Forged SAT 2041 Beta Ti face

  • More durable than the commonly used 6-4 Ti, with a more complex multi-thickness design.
  • Made possible by Mizuno's CORTECH Chamber.

• Unified sole unit

  • The carbon sole is now a single piece to shift weight to the outermost areas and increase overall stability.

• Straight flight bias

  • The mass is evenly distributed to promote a highly stable, straight ball flight.

• Modern player profile

  • Set low for low/mid spin performance and aligns square to open.

• Quick Switch Hosel

  • 4 degrees of adjustability.
