Why fitters matter more than ever with TaylorMade’s Qi4D | Fully Equipped

The possibilities are endless when it comes to the TaylorMade Qi4D driver, so you better know what you’re doing when you’re trying to find your proper setting.

On this week’s episode of GOLF’s Fully Equipped, co-host Johnny Wunder explained how much he learned about the driver after a fitting with TaylorMade Tour Rep Adrian Rietveld.

“These Qi4D heads are very nuanced, and I need to call that out now,” Wunder said. “You can screw that head up if you don’t know what you’re doing.
And I’ve said this a few times on this podcast, and just in videos, because you’re moving so much weight around, you really have to know.”

With the 12 settings on TaylorMade’s FCT loft sleeve and the four interchangeable weights that come stock with two 4 g weights and two 9 g weights, there are 128 combinations with just the stock weights and standard loft sleeves. That doesn’t account for the two other loft sleeves (1.5˚ and 1.0˚) available to TaylorMade tour fitters.

With so many options, the onus is on fitters now more than ever to truly be able to unlock the Qi4D driver.

“You really have to be a master at working with that much weight to move around and being able to understand TaylorMade’s different FCT sleeves that they have,” Wunder said. “So those drivers, I think as they go on, I think top fitters, your True Specs, your Club Champions, your cool clubs, some of the fitters at Golf Galaxy, PGA Tour Superstore, your top-tier fitters, your active fitters. By the time we get to the summertime, everybody will have figured it out.”

Wunder said his initial testing of the TaylorMade lineup with Charles Howell III, he was struggling to find the face because neither he nor Wunder really understood how to move the weight properly to fix it.

But after Wunder’s fitting with Rietveld, he could help him a little bit better.

“I said, ‘Hey, look, why don’t you take all the weight, the nines in the back and the fours in the front, swap those, put it in 10.5 and then move the lie to upright,'” Wunder said. “Because that’s what Adrian did with me and I was having the same problem with QI4D that Charlie was. I was having a hard time finding the right part of the face to optimize the numbers.

“Charlie does that, calls me 45 minutes later, is like, ‘Oh my God, okay, here we go, now we’re cooking.’”
