{"product_id":"r200-r180-cusco-lsd-zsm-tuned-japan-import","title":"R200 \/ R180 Cusco LSD — ZSM Tuned (Japan Import)","description":"\u003cp\u003eMost LSDs don’t come tuned for your specific chassis out of the box. Chassis weight, horsepower, and tire compound all have a direct impact on the optimal LSD setting — and without that tuning, you’re leaving performance on the table. This is the ZSM-tuned Cusco clutch-type LSD for the S30Z, built in collaboration with \u003cstrong\u003eCusco USA\u003c\/strong\u003e to create specific ZSM settings for both R200 and R180 differentials on the S30Z chassis.\u003c\/p\u003e\u003ch3\u003eWhy Cusco\u003c\/h3\u003e\u003cp\u003eCusco LSDs are the only differential on the market with a \u003cstrong\u003eforged housing\u003c\/strong\u003e. The stronger forged construction allows Cusco to optimize the strength-to-weight ratio, improving performance and reducing drivetrain losses. But the most important detail is the generous \u003cstrong\u003ewindowing\u003c\/strong\u003e on the housing itself — this allows significantly more oil to interface with the clutch plates than any other LSD on the market.\u003c\/p\u003e\u003cp\u003eThe increased oil flow delivers smoother engagements, better modulation, and more controlled differential temperatures. Keeping the clutch plates properly saturated with oil is critical for consistent, repeatable performance — on the street and on track.\u003c\/p\u003e\u003cp\u003eCusco, being a true racing-driven company, has engineered many adjustment points into their LSDs. That adjustability is what makes ZSM tuning possible.\u003c\/p\u003e\u003ch3\u003eZSM Tuning Process\u003c\/h3\u003e\u003cp\u003eFine-tuning an LSD is time-consuming. Every adjustment requires pulling the diff from the car and opening it up before changes can be made. ZSM is taking on that process — collecting data, testing on the S30Z chassis, and working with Cusco’s vast knowledge base to develop optimal settings for street and track use.\u003c\/p\u003e\u003cp\u003eIt’s not the parts list that makes the car — it’s the way it’s tuned. A carefully tuned car will always be more fun to drive and achieve higher performance levels.\u003c\/p\u003e\u003ch3\u003eBuild Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCusco clutch-type LSD — forged housing with generous oil windowing\u003c\/li\u003e\n\u003cli\u003eZSM-tuned settings specific to the S30Z chassis\u003c\/li\u003e\n\u003cli\u003eBuilt with all new OEM bearings and seals\u003c\/li\u003e\n\u003cli\u003eCompatible with R200 and R180 differentials\u003c\/li\u003e\n\u003cli\u003eSourced and tuned in collaboration with Cusco USA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReal Builds\u003c\/h3\u003e\u003cp\u003eThis differential was built for \u003cstrong\u003eJBZ Classics\u003c\/strong\u003e.
