The Tomei Technical Trax Type HX Pro Kit is designed specifically for the Z33 350Z, Fairlady Z and V35 (G35) Skyline. The kit includes the Tomei Trax 2 Way LSD with a Tomei 3.9 Final Gear Kit. Here is what Tomei has to say about their product:

The body of the Z33/V35 comes equipped with a naturally aspirated engine, despite the fact of the vehicle's fairly large build. Nissan's effort in creating this vehicle for its lively qualities comes from their decision to integrate the esteemed FR layout and fine weight distribution. However, the enjoyment of driving can be enhanced further with a limited slip differential unit. Tomei Powered has combined a final gear set with this LSD for more improved handling and quicker throttle reaction. The characteristics of the vehicle are drastically changed with the installation of this kit. Overall, the car will be highly responsive and comply with the driver's every instruction.
