Sport RWD 400Z \/ RZ34 models use an open differential, which can allow one rear tire to spin during acceleration or corner exit. Performance, Heritage Edition, and NISMO RWD models use a factory mechanical LSD, but its mild tuning prioritizes daily drivability and quiet operation.\u003c\/p\u003e\n\u003cp\u003eThe TOMEI Technical Trax Advance LSD firmly transfers driving force to both rear tires. The result is stronger rear grip on corner exit, improved acceleration, better straight-line stability, more direct rear contact feel, and greater confidence on circuits, during drifting, and on winding roads.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eStrong lock-up from a high-capacity clutch-disc structure\u003c\/li\u003e\n\u003cli\u003eDesigned to maximize rear traction in FR sports cars\u003c\/li\u003e\n\u003cli\u003eImproved power transfer during corner exit\u003c\/li\u003e\n\u003cli\u003eEffective for improving circuit lap times\u003c\/li\u003e\n\u003cli\u003eImproved rear-vehicle control during drifting\u003c\/li\u003e\n\u003cli\u003eDirect FR driving feel suitable for performance street use\u003c\/li\u003e\n\u003cli\u003eFully machined case for high strength, reduced weight, and additional internal disc capacity\u003c\/li\u003e\n\u003cli\u003eLarger-diameter inner- and outer-tooth discs for increased effective friction area\u003c\/li\u003e\n\u003cli\u003e24 total clutch discs (12 per side), compared with 10 total (5 per side) in the referenced OEM LSD\u003c\/li\u003e\n\u003cli\u003eGreater friction area for stronger lock-up, improved wear resistance, and stable operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e2-Way Characteristics\u003c\/h3\u003e\n\u003cp\u003eA 2-way LSD provides strong operation during both acceleration and deceleration, allowing the driver to actively control rear-vehicle posture.
