Spin Rate is generated primarily by Spin Loft and club speed. Spin Loft =Dynamic Loft-Attack Angle. The high spin rate is caused by a combination of two factors. If for example the Static Loft of your driver is 10 degrees and the Dynamic Loft (the loft of the club at impact) is 15 degrees you will generate a high Spin Loft. If you have a negative Attack Angle of say 3 degrees (hitting down) you will increase Spin Loft. In this example the Spin Rate would be 15 minus -3 or 18. An ideal Spin Rate is 10-12 depending on club speed. With a driver shots that generate a high Launch Angle and high Spin Rates are usually caused by a high Dynamic Loft. A shot that has a good Launch Angle of 12 to 14 degrees and a high Spin Rate is usually caused by a Negative Attack angle. Both of these issues can be corrected by changing the ball position and the way you deliver the club to the ball. The best tool to provide feedback is Trackman. A simple solution to fixing a high Dynamic Loft issue is to get a Driver with a very low Static Loft in the 5-7 degree range combined with a shaft that is suited to your swing.
