Speed starts here. The new Qi4D driver isn’t just fast, it’s engineered for precision, forgiveness, and performance across the face. Early testing shows ball speed gains, tighter spin windows, and confidence at address.
Here’s what our players are seeing as they put Qi4D through its paces.
Qi35 Ball Speed: 168.3 vs. Qi4D Ball Speed: 170.2 (+1.9mph)
Qi35 Carry: 309 vs. Qi4D Carry: 313.4 (+4.4 yards)
Fitting Notes
Jayden gained +1.4mph ball speed in moving from Qi35 to Qi4D, he then unlocked +1.9mph with a reduction of 334rpm of spin with the Qi4D LS head. Built 0.25' stronger and flatter, it delivers speed, consistency and a tighter spin differential.
Gamer: Qi4D LS | 9°| Ventus Velocore+ 6X Red
Qi35 Ball Speed: 185.1 vs. Qi4D Ball Speed: 187.4 (+2mph)
Qi35 Carry: 318.6 vs. Qi4D Carry: 325.2 (+6.6 yards)
Fitting Notes
Angel picked up +2.2 mph ball speed and cut spin by 335 rpm with Qi4D, keeping speed high across the face. After dialing CG heel-side to protect his miss, weight options turned bad spin into good—confirmed with 192 mph ball speed before heading to the first tee.
Gamer: Qi4D | 9°| Tensei 1K White 70tx
Qi35 Ball Speed: 170.3 vs. Qi4D Ball Speed: 171.6 (+1.3 mph)
Qi35 Carry: 307.2 vs. Qi4D Carry: 310.3 (+3.1 yards)
Fitting Notes
Martin’s first fitting delivered +1.3 mph ball speed and a drop in spin of 427 rpm, with a stronger low-heel strike—his usual miss. We’re looking to unlock even more with an LS 10.5° head during this week’s Dubai Invitational.
Gamer: Qi4D LS | 10.5°| Ventus Velocore+ 6X Blue
Qi35 Ball Speed: 175.1 vs. Qi4D Ball Speed: 177.8 (+2.7mph)
Qi35 Carry: 299.3 vs. Qi4D Carry: 304.8 (+5.5 yards)
Fitting Notes
Ryggs moved to Qi4D and gained 2.5 mph ball speed without losing forgiveness. After refining technique, TrackMan clocked him at 180+ mph, +3.5 mph faster than his Qi35—with a look at address he trusts and zero right-side misses.
Gamer: Qi4D | 9°| PX Hzrdus Yellow Gen 5 70TX
Qi35 Ball Speed: 144 vs. Qi4D Ball Speed: 147 (+3 mph)
Qi35 Carry: 238 vs. Qi4D Carry: 243 (+5 yards)
Gamer: Qi4D LS | 10.5°| Diamana TB 50 S
Fitting Notes
After gaming a Qi35 10.5 driver since the BMW PGA at Wentworth Club, he switched to Qi4D and gained +1.1 mph ball speed with a reduction in spin of 211 rpm. A quick tweak with FCT gave him the perfect look—and after 18 holes, his message said it all: “Can I play it? I’m excited.”
