The company is both a major OEM powertrain supplier and a long-established performance-clutch manufacturer, with products engineered for everything from original-power street cars to dedicated motorsports use.\u003c\/p\u003e\u003ch3\u003ePurpose \u0026amp; Application\u003c\/h3\u003e\u003cp\u003eEXEDY flywheels are engineered as matched driveline components rather than cosmetic weight reductions. Its lightweight performance flywheels use one-piece billet or forged chromoly steel construction to reduce rotational inertia while retaining high thermal capacity and integrated ring-gear strength.\u003c\/p\u003e\u003cp\u003eA lighter flywheel can improve engine response and rev matching, but it can also reduce stored rotational energy and make low-speed takeoff more sensitive. It is best suited to drivers who value throttle response, faster transient behavior, and performance use over maximum factory-like smoothness.\u003c\/p\u003e\u003ch3\u003eConfiguration\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEXEDY Part Number:\u003c\/strong\u003e NF04\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Lightweight Flywheel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction \/ Character:\u003c\/strong\u003e EXEDY application-specific flywheel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTorque Rating:\u003c\/strong\u003e Not rated independently as a clutch torque-capacity figure\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBest Suited For:\u003c\/strong\u003e Clutch service or performance builds requiring the listed EXEDY flywheel fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhich Option Makes Sense?\u003c\/h3\u003e\u003cp\u003eFor 2003–2007 INFINITI G35 \/ 2003–2006 Nissan 350Z, this configuration makes the most sense when its intended duty matches the vehicle's actual power and use.
