Titleist GTS4 Driver Review: The Low-Spin Specialist Goes Mainstream

Titleist has always been a brand that understands its core user, and nowhere is that more evident than in the low-spin ‘4’ series drivers. Historically, these have been sub-460cc, niche products reserved for the highest of swing speeds. However, with the launch of the GTS4, the narrative may have been altered slightly...

The headline change here is the move to a full 460cc chassis. This immediately opens the GTS4 up to a much wider audience than the GT4 of last season, while under the hood, the performance is driven by the new Split Mass Frame and the Thermoform Body.

By doubling the amount of Proprietary Matrix Polymer (PMP) to 26 grams, Titleist has unlocked an incredible amount of discretionary weight. In the GTS4, this is utilized through a dual-weighting system featuring a heavy forward track weight and a flat weight in the AFT (rear). This is supported by the Speed Sync Face, which is designed to keep ball speeds high even when you wander away from the center of the cup face.

The most significant functional shift in the GTS4’s design is the introduction of a forward weight track, a feature that was notably absent from the previous GT4. While the older GT4 relied on a simpler 'flip' system - swapping two interchangeable weights between fixed forward and aft ports - the GTS4 adopts the more precise track technology previously reserved for the ‘3’ series.

From the top, the GTS4 is predictably Titleist - which is a very good thing. It sits beautifully square, and despite the increase in volume, it retains a sophisticated, tour-inspired shape that masks its size well. It frames the ball with a level of cleanliness that Titleist loyalists have come to expect.

However, I have to mention a couple of recurring aesthetic gripes. On every model I received for testing, the finish around the new silver back port was a little scruffy. I noticed several areas where the black paint had bled onto the silver or pooled to create small, unwanted lumps. At this price point, you expect the details and shelf appeal to match the premium performance.

While the highly polished sole is a highlight out of the wrapper and certainly reinforces the premium Titleist branding, the longevity of the finish is a concern; a single 18-hole test session left it looking unexpectedly and excessively weathered in my opinion.

It’s a great-looking design choice initially, but perhaps less practical for long-term shelf appeal once it actually hits the turf.

On the Foresight Sports GC3 launch monitor, the GTS4 proved to be two highly effective drivers in one.

With the heavy weight in the forward setting, it is still a very aggressive spin-killer, so high-speed players looking to flatten out their flight will continue to find it produces piercing, low-spin bullets.

However, the real magic happened when I moved the heavier weight to the 'AFT' (rear) setting. In this configuration, the GTS4 becomes a brilliant ‘in-betweener.’ It’s almost like a ‘GTS2.5,’ sitting right in the middle of the GTS2 and GTS3 launch and spin windows.

This versatility makes it arguably the most intriguing head in the lineup; it offers the aggressive speed of a low-spin head but with a launch window that won't punish the mortal golfer.

Off-center hits (heel and toe) provided a somewhat strange sensation, however, and this was apparent across the whole GTS range for me.

In terms of feel, I actually found it a little less pleasant, slightly harsher, and more hollow on mishits than the previous generation GT3 or GT4, with my suspicions being that extending the proprietary matrix polymer so far around the chassis contributes to this somewhat more abrasive feedback.

However, as with the entire range, that harsh feel didn't match the numbers. Even on my poorest contacts, the data - specifically ball speed and spin- remained remarkably steadfast.

To me, this was actually a great combination: honest, unfiltered feedback through the hands that tells you exactly where you missed it, but coupled with data that remains largely unaffected. This is something better players will love, in my opinion.

With the upgrades in shaping, size, and weighting, the GTS4 is no longer a niche specialist; it is a mainstream powerhouse that will likely become the most popular '4' model Titleist has ever released.

The new GTS driver lineup offers a comprehensive range of high-performance shaft options to suit every swing profile. The Featured selection includes the Project X Titan Black alongside the Mitsubishi Tensei 1K series (available in White, Blue, and Red variants).

For golfers seeking an upgraded experience, Premium shaft offerings include the Graphite Design Tour AD DI, VF, and FI models.

The GTS drivers are available for fittings and pre-sale immediately, with a global retail launch scheduled for June 11. Pricing is set at an RRP of £629 for standard configurations and £799 for premium options.
