As a current TaylorMade R7 Quad owner, it's hard to conceive that the new TaylorMade R7 425 Quad could be that much better than the original. We'll I did some research and I was pleasantly surprised that TaylorMade was able to squeeze more out of the new R7 425 Quad. While this isn't quite a TaylorMade R7 425 review, it does provide some details on why the new one performs better.

Here are the nitty-gritty details between the R7 425 Quad vs. R7 Quad:

- 17% more movable weight- 7% increase in MOI

- 45% larger span of horizontal CG movement

- 30% broader range of lateral shot adjustment

- 13% increase in backspin-rate adjustment

- 9.3% larger address footprint

- 25% thinner clubhead walls / 40% thinner than the average cast metalwood

- 33% lower CG location relative to the center of the clubface

All of the above means that the R7 425 TaylorMade Driver promotes a wider change in shot-shape and trajectory; is more forgiving; and visually encourages increased confidence.

When comparing the two I found the new one engineered to deliver more of a draw when the cartridges are positioned for a draw. The R7 425 Quad also produces a higher launch angle to promote a higher flight when the cartridges are positioned for a high-neutral trajectory.

Another big difference between the R7 425 Quad and the original is the center of gravity location relative to the center of the club face. The new 425 has a CG position 3.3 mm below the center of the face compared to 2.5 mm for the original, which gives the R7 425 Quad more clubface area above the CG. This in turn activates the vertical-gear effect, which occurs when the top of the club face moves back and away from the target at impact. This produces a higher launch angle and a lower spin-rate, which is ideal launch conditions for added distance.

The new R7 425 also incorporates Taylor Made's third generation Inverted Cone Technology (ICT). It also has TaylorMade's new RE*AX Technology shaft, which prevents ovaling. Ovaling causes the shaft to load and release energy inconsistently, which is delivered to the club face and then to the ball. The R7 425 Quad is an amazing club, which also comes in a TP model that's being used by a lot of the pros. If you're in the market for a new driver I highly suggest looking into TaylorMade's line of drivers.
