JDM tolerances and Yonex Ezone driver

drugazi · June 21, 2014

So I often see people on this forum talking about how JDM golf clubs have higher tolerances. I play nearly all JDM but I don't buy into all the hooplah. Anyway, I recently wanted to switch from my 10* Yonex Ezone to a 9* degree to hit it lower. I obviously didn't want to make the switch if the loft wasn't actually lower on the 9*. I took it in to the local shop and was FLOORED by the results. The club maker measured my 10* at 9.5* and the 9* at 8.5*. The two drivers were exactly 1* apart. I'll chalk up the .5* to fluctuations in the tools used to measure but the consistency of 1* less loft amazed me. Talk about tolerances!

jdm is made better, more care and better made for sure. Weather that translates into better results is up for debate. Pga tour pros and web.com players use mostly all us made stuff and they are pros. Vokey with his sm5 and massive amt of grinds he offers in wedges has really taken the step forward to making his product special. I think its mostly how we the players feel playing certain top end stuff and emotions matter alot.

The difference is that what the tour guys are using is more like JDM than what you're gonna get off the rack at GG or Dick's. i.e., they're all gonna be spot-on as far as head weight, loft and lie. Try getting that at your local big box. And sure, you can fix lofts and lie angles. Head weights, no so much. I've had a 6-iron head weigh 2 grams more than a 7-iron before on some TM heads. Imagine how much lead had to be used to get it to weigh right. Tour guys ain't playing those. And you won't find it in good JDM clubs.
