In a manual transmission like the one in the 370Z, the clutch acts as the bridge between the engine and the transmission.

A aftermarket 370Z clutch kit isn't just about smooth gear shifts; it's also about performance. A good clutch will offer a quicker and more precise engagement, allowing for better acceleration and more control when driving at high speeds. This is especially important in a sports car like the 370Z, where every second counts whether you're on the track or just enjoying a spirited drive.
If you're experiencing slippage, where the engine revs but the car doesn't accelerate as it should, or if you're hearing strange noises when the clutch engages, it's probably time for a new clutch. Other signs include a stiff or loose clutch pedal and difficulty in changing gears. Don't ignore these symptoms; a failing clutch can lead to more severe problems down the line.
The organic clutch is the most common type and is often found in stock 370Zs. Made from organic material like fiberglass or brass, these clutches are known for their smooth engagement and are ideal for daily driving. However, they may not be the best choice for aggressive driving or racing due to their limited heat tolerance.
Ceramic clutches are designed for high-performance situations. They offer excellent heat resistance and are great for aggressive driving styles, but they can be a bit harsh for daily driving. The engagement is more abrupt, which can be a pro or a con depending on your driving needs.
Kevlar clutches are a middle-ground option, offering smoother engagement than ceramic but better heat resistance than organic clutches. They're durable and long-lasting, making them a good choice for those who want a blend of performance and daily drivability.
Multi-disc clutches are the beasts of the clutch world. These are generally twin or triple-disc setups that offer incredible torque capacity and heat dissipation. They're generally overkill for daily driving, with the main use cases for them turbo and or supercharger builds or track prepped Z34s..
