The biggest difference is forgiveness. The GTS4 grows to a 460cc head, up from the GT4's 430cc, and testers call it the most forgiving "4" Titleist has made. The GT4 is the least forgiving head in the GT range, and you clearly feel off-centre strikes. Both are very low-spin heads for fast swingers that give a penetrating flight. At 10° they share a 58.5° lie and a 45.5-inch length.
Sound and looks also set them apart. Testers are split on the GT4's sound and on its compact look at address. The GTS4's muted, refined sound and clean, traditional look go down well. The GTS4 costs more than the model before it, and its low-lofted stock setups can launch too low. Fitting matters for both.
Choose the GT4 Driver if…
you're a consistent ball-striker who likes a compact 430cc head and wants a driver that makes it easy to shape draws and fades.
Choose the GTS4 Driver if…
you swing at roughly 105 mph or faster and want low spin in a larger 460cc head that forgives more on mishits, with an adjustable CG track for fine-tuning.
Common questions
- Which is more forgiving?
- The GTS4. Testers call it the most forgiving '4' Titleist has made, while the GT4 is the least forgiving GT head, though the GTS4 still gives up more on mishits than the GTS2 or GTS3.
- Is it worth upgrading from the GT4 to the GTS4?
- It may be if you want more forgiveness, a larger 460cc head and a sound and look that testers like more. Keep in mind that the GTS4 costs more, and its low-lofted setups can launch too low without a proper fitting.
- Are these drivers suitable for slower swingers?
- Not really. Slower swingers may find the GT4 launches too low and spins too little to carry well, and the GTS4 overview says slower swingers will likely do better with another head in the GTS range. For GT4 players who want more help, its overview suggests the rear weight setting or the GT2 or GT3.
