What kind of driving is this SPEC Stage 3+ clutch kit best suited for?

This Stage 3+ clutch kit is designed for drivers who have modified their G35 or 350Z with significant engine upgrades, such as turbochargers or superchargers. It's ideal for track use, drag racing, or any situation where the vehicle experiences high torque and heat.

What is the difference between a sprung and solid hub clutch disc?

A sprung hub clutch disc has springs that help absorb torsional vibrations and shock from the drivetrain, leading to a smoother engagement and reduced drivetrain stress. A solid hub disc, often found in more basic or heavy-duty applications, lacks these springs and offers a more direct, sometimes harsher, connection.

Does this clutch kit come with a new flywheel?

This SPEC Stage 3+ clutch kit includes the clutch disc, pressure plate, and pilot bearing. A flywheel is not included in this specific kit, so you will need to reuse your existing flywheel or purchase one separately if it is worn or damaged.

Product Details

This SPEC Stage 3+ clutch kit, part number SN353F, is built with a high-performance sprung clutch disc featuring a carbon-ceramic friction surface. This material choice is key for handling the increased torque and heat generated by more powerful engines, offering a strong engagement that can stand up to aggressive driving. It's designed specifically for the 2003-2006 Infiniti G35 and the 2003-2006 Nissan 350Z, ensuring a direct fit for these popular sports cars.

The Stage 3+ designation means this kit is a significant step up from stock, intended for drivers who have made modifications to their vehicle's engine and drivetrain, such as forced induction or extensive engine tuning. The carbon-ceramic disc provides excellent friction and heat dissipation, which is crucial for preventing clutch fade during repeated hard launches or track use. The sprung hub design helps to dampen drivetrain shock, offering a more comfortable engagement than a solid hub disc, even with its high performance capabilities.

Included in this kit is the clutch disc, a high-clamp load pressure plate, and a pilot bearing. While this kit is well-suited for modified vehicles, it's important to note that it is a performance-oriented upgrade. Drivers should expect a firmer pedal feel compared to the factory clutch, and engagement may be more abrupt, especially at lower speeds. This is a common characteristic of high-performance clutch systems designed for maximum power transfer and durability under demanding conditions. For optimal performance and longevity, it's recommended to have this clutch installed by a qualified technician following manufacturer guidelines.
