The JHHFront Differential for the Nissan R32-34 GT-R will transform its road holding and ability to put power down coming out of bends. If you have a more powerful GT-R or enjoy driving the car on track you will appreciate the addition assistance and balance the JHH Front Differential will provide.
The problem with the standard front differential on the R32-R34 GT-R is that it is an open design. This can result in the inside front wheel losing traction as the car squats coming out of corners on power.
The great benefit of the JHH Front Differential is that it automatically biases torque, with a constantly varying degree, to the wheel that has traction. This massively reduces inside wheel slip without any negative side effects. For example, they are silent (using gears rather than clutch plates), use standard oil and do not need servicing any more than the standard item. They are also fine to use on the road and do not limit your steering lock or cause inside wheel 'hop' on full lock when parking. Essentially the same design as the front differentials installed in the very best front wheel drive cars this ability to seek out more traction provides real benefits to the chassis performance and driver confidence with the GT-R.
We feel that the JHH Front Differential is a must for a track-biased GT-R but also compliments a high performance road car very well. The increased steering feel, front-end grip and stability make a huge difference on any R32-R34 GT-R.
