To design Callaway’s latest driver, the 2013 Razr Fit Xtreme, company engineers broke down the key ingredients of its most successful drivers models, realigning them with new technology that makes the Razr Fit Xtreme lower spinning, more forgiving and deliver more ball speed than its predecessor, the 2012 Razr Fit driver.
The Razr Fit Xtreme is also Callaway’s widest ranging driver offering according to Evan Gibbs, manager of performance analysis and club configuration for Callaway. This is because the lower-lofted Razr Fit Xtreme drivers (8.5 degrees, 9.5 degrees and 10.5 degrees) have different performance characteristics than the higher-lofted drivers (11.5 degrees and 13 degrees).
The OptiFit Hosel adjusts the face angle to an Open, Square, or Closed position at address and the OptiFit Weights (13 grams and 1 gram) also shift the clubhead’s CG to help you play a Draw or Neutral ball flight off the tee.
The lower-lofted Razr Fit Xtreme drivers are modeled after Callaway’s FT Tour drivers, which were extremely popular on the PGA Tour. While the Razr Fit found its way into the bags of many better players and tour players, Callaway received feedback that many preferred the lower-spinning FT Tour drivers to the higher-spinning Razr Fit.
“We took a step back and looked at how each loft was going to be played,” Gibbs said. “We saw that better players wanted a smaller footprint and a more penetrating trajectory, while higher-handicappers wanted larger, more forgiving footprint and more spin for optimum distance.”
In order to lower the spin rate of the Razr Fit Xtreme, Callaway engineers needed to lower the driver’s center of gravity (CG), which they did by removing weight from the driver’s “Forged Composite” crown. Engineers also thinned the perimeter of the “Speed Frame Face” that was used on the Razr Fit driver.
This Speed Frame Face creates incredibly fast ball speeds all across the face for longer, more consistent distance.
The thinner face, combined with Callaway’s updated “VFT” and “Hyperbolic Face Technology,” adds more speed to mishits according to Gibbs. The face also has more curvature than in previous Callaway drivers, which helps straighten out off-center strikes.
The weight saved from the face (about 3 grams) was moved to more optimal positions such as the rear toe section of the sole, where it deepens the center of gravity and makes the Razr Fit Xtreme’s adjustable weights more symmetrical, adding stability to the head.
These changes have resulted in more distance and less spin for Callaway Staffers like Luke List, who led all tours in driving distance in 2012. Gibbs said that during testing List picked up 16.6 yards with the new driver compared to his Razr Fit, adding 0.6 mph of ball speed and reducing his spin rate by almost 500 rpms.
Like the Razr Fit, the Razr Fit Xtreme driver allows golfers to adjust the face angle to one of three settings: neutral, open and closed. But the lower-lofted and higher-lofted models have two very different appearances at address.
The lower-lofted models measure 440cc and have a 1-degree open face angle at the neutral setting. Changing the Opti-Fit Hosel to the open setting on these drivers will open the face another 1.5 degrees, resulting in a face that is 2.5 degrees open at address. If they are adjusted to the closed setting, the face will rest 0.5 degrees closed.
The higher-lofted drivers measure 460cc and are longer heel-to-toe than the lower-lofted versions. This places the sweetspot of the club closer to the hosel, which increases draw bias. The higher-lofted models also sit in a square position when set in neutral, meaning they can be adjusted to either 1.5 degrees open or closed.
On both the lower-lofted and higher lofted drivers, changing to the face angle will also change the loft of the club. The closed setting adds 1 degree of loft to the neutral setting (a 9.5-degree driver becomes a 10.5-degree) while the open setting subtracts 1 degree (a 9.5-degree driver becomes an 8.5-degree). According to Gibbs, Callaway’s testing showed that better players had a tendency to use the Opti-Fit Hosel to adjust loft, while higher handicap players used it to correct a hook or slice.
One of the most important features of the Razr Fit Xtreme drivers to consumers could potentially be the stock shaft offerings. Many OEMs install stripped-down versions of popular shafts in their drivers that have altered characteristics. For Callaway’s newest lineup, the company decided to use an unmodified Aldila Trinity shaft, as well as unmodified Matrix Black Tie7M3 shaft. The Matrix shaft alone carries a $300-plus price tag at retail, making the retail price of the Razr Fit Xtreme, $399, all the more impressive. The Callaway Razr Fit Xtreme drivers will be available at retail on Jan. 18, 2013.
