Chassis weight, horsepower, and tire sizing have a direct impact on the optimal LSD settings.\u003c\/p\u003e\n\u003cp\u003eCusco, being a true racing-driven company, has engineered numerous adjustment points into their LSDs. Working with their expertise, our goal is to develop specific ZSM S30z settings for both R200 and R180 differentials.\u003c\/p\u003e\n\u003ch3\u003eThe Cusco Advantage: Forged Housing\u003c\/h3\u003e\n\u003cp\u003eCusco LSDs are the only differentials on the market with a forged housing.

For this reason, we're taking it upon ourselves to go through this process and collect data on optimal settings.\u003c\/p\u003e\n\u003cp\u003eWith our extensive testing and Cusco's vast knowledge, we're excited to bring more S30z-specific performance parts to the market.\u003c\/p\u003e\n\u003ch3\u003eThe ZSM Philosophy\u003c\/h3\u003e\n\u003cp\u003eIt's not the parts list that makes the car - it's the way it's tuned, whether for street or race.
