Tomei Technical Trax Advance LSD (2 Way) - Nissan Fairlady Z / 400Z RZ34 6MT 2023+

Description

The 350Z / 370Z / 400Z RZ34 is an FR sports car with extremely high performance potential. However, to truly bring out its power and the enjoyment of rear-wheel drive, the performance of the rear differential is extremely important. The TOMEI TECHNICAL TRAX ADVANCE LSD is a serious mechanical LSD developed to further enhance the traction performance, cornering stability, and rear-wheel-drive control.

Why Does the 350Z / 370Z / 400Z RZ34 Need an Upgraded LSD?
- For drivers who truly want to enjoy the performance, upgrading the LSD is an extremely important tuning item. Especially on 400Z Sport grade vehicles that are not equipped with an OEM LSD, driving force cannot be efficiently distributed to both rear tires during acceleration or corner exit, and one rear tire may spin. This prevents the vehicle from fully transferring its power to the road surface, leading to reduced traction and unstable vehicle behavior.
- On the other hand, 400Z Performance, Heritage Edition, and NISMO models are equipped with an OEM mechanical LSD, but the OEM LSD has mild characteristics that prioritize daily drivability and quiet operation. For drivers who want sharper rear-end control during sports driving, circuit use, drifting, or winding roads, stronger locking performance and improved response are required.
- The TOMEI TECHNICAL TRAX ADVANCE LSD increases rear grip during corner exit and firmly transfers driving force to both rear tires, greatly improving acceleration performance, straight-line stability, and rear contact feel. It brings out the true enjoyment of an FR sports car, including improved lap times on the circuit, better control during drifting, and greater confidence on winding roads.
- To unlock the true potential of the 350Z / 370Z / 400Z RZ34, a LSD is truly an essential drivetrain tuning item.

Features of the TOMEI TECHNICAL TRAX ADVANCE LSD
- Strong locking performance with a high-capacity clutch disc structure
- Designed to maximize rear traction performance for FR sports cars
- Improved driving force transfer during corner exit
- Effective for improving lap times during circuit driving
- Improved rear control during drifting
- Direct FR driving feel that can also be enjoyed on the street
- TOMEI TECHNICAL TRAX ADVANCE LSD does not have the mild operating feel of an OEM LSD. Instead, it has more aggressive characteristics suited for sports driving. Therefore, operating noise and tire dragging may occur during low-speed turns or in parking lots. However, this is proof of a true mechanical LSD, and it transforms the driving experience into something more direct and enjoyable.

Comparison between TOMEI TECHNICAL TRAX ADVANCE LSD and the OEM LSD
- Casing - The TOMEI LSD uses a fully machined case, while the OEM LSD uses a case structure made by machining a cast material. This fully machined construction allows the TOMEI LSD to secure more internal space for additional clutch discs while achieving both high case strength and weight reduction.
- Disc - For both the external-teeth and internal-teeth types, the TOMEI LSD uses larger-diameter discs with a greater effective friction area compared to the OEM LSD. This increases the total friction surface area, allowing the LSD to generate stronger lock-up force.
- Pressure Ring - For both the external-teeth and internal-teeth types, the TOMEI LSD uses larger-diameter discs with a greater effective friction area compared to the OEM LSD. This increases the total friction surface area, allowing the LSD to generate stronger lock-up force.
- Internal parts - The TOMEI LSD uses 12 discs per side, for a total of 24 discs, while the OEM LSD uses 5 discs per side, for a total of 10 discs. By increasing the number of discs, the TOMEI LSD provides a greater friction surface area, delivering stronger lock-up force, improved disc wear resistance, and more stable LSD operation.

Choosing Between 1.5WAY and 2WAY
- 1.5WAY - Emphasizes locking performance under acceleration while being easier to control during deceleration than a 2WAY. Recommended for Street driving, winding roads, circuit driving, grip driving
- 2WAY - Strong operation during both acceleration and deceleration, allowing the driver to actively control rear vehicle posture. Recommended for Drifting, circuit driving, aggressive sports driving
