Review ACT Hd/perf Sprung Clutch Kit Heavy Duty Pressure Plate And fits STREET

Introducing the ACT NS1-HDSS HD/Perf Street Sprung Clutch Kit, a high-performance upgrade for your Honda Civic Type R. This clutch kit is specifically designed for daily driving and track use, providing improved clamping force, better pedal feel, and enhanced durability.

The pressure plate in this kit is engineered using high-quality materials, including a robust steel construction and a carbon fiber friction material. The carbon fiber material offers superior heat resistance, ensuring consistent clutch performance even during prolonged high-performance driving. The pressure plate also features a sprung hub design, which helps to absorb engine shock and reduces transmission harmonic vibration.

The clutch disc in this kit is also made of high-performance materials, including a Kevlar and ceramic composite construction. This material combination offers excellent heat resistance, low wear, and smooth engagement. Additionally, the disc features a high clamping force, which helps to improve power transfer and reduce slippage.

The flywheel in the ACT NS1-HDSS HD/Perf Street Sprung Clutch Kit is machined from a solid billet of aluminum, ensuring optimal mass and rigidity. It also features a precision-machined surface for perfect clutch engagement. The flywheel is also lightweight, which helps to reduce rotational mass and improve engine response.

The clutch kit comes with all necessary hardware for installation, including bolts, bushings, and pilot bearings. The kit also includes a new release bearing and a new throw-out bearing, ensuring a smooth and reliable clutch engagement.

In summary, the ACT NS1-HDSS HD/Perf Street Sprung Clutch Kit is a high-performance upgrade for your Honda Civic Type R. It features a carbon fiber pressure plate, a Kevlar and ceramic clutch disc, and a lightweight aluminum flywheel, all designed for improved clamping force, better pedal feel, and enhanced durability. The kit comes with all necessary hardware for installation and includes new release and throw-out bearings.

Buying an ACT (or any other brand) HDSS (High Performance Street Sprung) clutch kit for a HD (Heavy Duty) application involves considering its pros and cons to determine if it's the right choice for your vehicle.

1. Enhanced clamping force: The HDSS clutch kit provides a stronger clamping force than the stock clutch, which is beneficial for towing heavy loads, hauling trailers, or for high-performance driving.

2. Improved pedal feel: The HDSS clutch kit offers a more responsive and consistent pedal feel, making it easier to modulate the clutch during shifting.

3. Durability: The HDSS clutch kit is designed to handle the increased demands of heavy-duty applications, ensuring longer clutch life.

4. Smoother engagement: The HDSS clutch kit provides smoother clutch engagement, which can lead to better shifting and reduced wear on the synchronizers.

1. Cost: The HDSS clutch kit is more expensive than a stock clutch kit due to its higher performance capabilities.

2. Installation complexity: Installing the HDSS clutch kit may be more complex than a stock clutch kit due to its heavier design and additional components.

3. Increased noise: The HDSS clutch kit may produce more noise during operation due to its increased clamping force and heavier design.

4. Potential vibration: The HDSS clutch kit may experience some vibration during operation, especially when towing heavy loads or under high-performance driving conditions.

The ACT HDSS HD/perf street sprung clutch kit offers several advantages, including enhanced clamping force, improved pedal feel, durability, and smoother engagement. However, it comes with some drawbacks, such as increased cost, installation complexity, noise, and potential vibration.

If you frequently tow heavy loads, haul trailers, or engage in high-performance driving, the benefits of the HDSS clutch kit may outweigh the drawbacks. However, if you have a lighter application and are looking for a more budget-friendly option, a stock clutch kit may be more suitable for your needs.

Based on the information provided, I would recommend the ACT HDSS HD/perf street sprung clutch kit for those who require the increased clamping force and durability for heavy-duty applications or high-performance driving. However, those with lighter applications should consider a stock clutch kit to save on cost and installation complexity.
