AutoQuest Motorsport - It's Done! The 981 Cayman S/GTS/GT4 Shorter Final Drive Ratio
One of the most common complaints about the GT4 has been the long gearing. This is especially prevalent on the track where it takes a good bit of time to rev through the powercurve, and you’d be hard pressed to find a track anywhere in the world where you’d ever use 6th gear. The factory final drive ratio has a top speed equivalent of 201mph, which sacrifices the intensity of the acceleration curve and leaves us with a GT4 that is not nearly as quick or responsive as it could be on track and not as exciting as we’d like on the street.
We have spent over 18 months researching and developing a new crown ring and pinion to shorten the final drive ratio. Our new ratio is 19% shorter, reducing the final drive from 3.89 to 4.62. Our new shorter final drive ratio is now perfectly suited for track use, and much more exciting for street driving. It is much more responsive, feeling similar to having an additional 50hp at your disposal.

Installation
Replacing and setting up a crown ring and pinion correctly can be a challenging task and requires specialized experience. To maintain our 12 month product warranty, we have made arrangements with one of the leading Porsche Transmission Specialists in the US, BMC & G in Ohio, to perform the installation and assist in the shipping of your transmission.

This is awesome, John! Always been one of my main "gripes" with the GT4. Have you been able to put together any video of a GT4 running your R&P?
