Advanced Clutch Solutions (ACS) is a well-known brand in the automotive community, particularly for their high-performance clutches used in various applications, including the Mazda RX-7 with the Eclipse Evo engine swap. Here is a list of pros and cons of buying an ACS 4240508 act pad sprung race disc for your Mazda RX-7 Eclipse powertrain setup.
Pros:1. High Clamping Force: This clutch offers a higher clamping force compared to stock or OEM clutch alternatives. It is designed to handle the increased power output of an Eclipse engine in an RX-7, ensuring it can transfer power efficiently.
2. Durability: The race disc design makes it more robust and capable of handling heavier use and high horsepower levels, allowing you to push your engine harder during track days or racing events.
3. Smoother Shifts: The spring-centered design aids in smoother clutch engagement, which reduces the chance of power interruption during gear shifts. This results in better driving experience and consistency during track sessions or day-to-day driving.
4. Temperature Resistance: The advanced clutch material used (such as ceramic or organic) is better suited to resist temperature fluctuations, ensuring power is consistently transferred regardless of operating conditions.
5. Lightweight: The ceramic material used in the clutch disc is lighter than a steel clutch disc, making it easier for the flywheel to spin up, resulting in quicker acceleration and better overall performance.
Cons:1. Cost: The advanced clutch setup is expensive compared to a stock or OEM clutch. It costs significantly more, making it a considerable investment for some enthusiasts.
2. Requires Special Installation: Installing a high-performance clutch may require the skills of a professional gearbox technician or experienced mechanic. Different installation techniques might be needed depending on the specific clutch setup used, which can add to the overall cost.
3. Noise Level: Ceramic clutch discs can produce higher noise levels than OEM or stock items as they tend to have a different friction material and engagement characteristics. This can make the driver cabin less quiet, which might not be desired by some.
4. Vibration: A high-performance clutch system may transmit more vibration through the drivetrain. This can be challenging to cope with when driving daily, especially when compared to a stock or OEM clutch, which tends to have a smoother engagement.
Conclusion:If you're planning to upgrade your Mazda RX-7 with an Eclipse Evo engine, an ACS 4240508 act pad sprung race disc clutch could contribute to overall better performance, increased durability, and faster gear engagement. However, this clutch setup demands a significant investment and specialized knowledge to install. Additionally, an increase in noise level and more pronounced vibrations should be expected. If you primarily drive your car daily, it's essential to consider the cost, installation complexity, and noise levels before deciding to upgrade to this advanced clutch system.
Recommendation:For racers, drag racers, or dedicated track day enthusiasts aiming to extract maximum performance from their Mazda RX-7 Eclipse swap, the ACS 4240508 act pad sprung race disc is a recommended choice. Alternatively, if you value a smoother driving experience, are operating on a budget, or are primarily using your RX-7 for daily commuting, you may wish to consider a stock or OEM clutch disc to maintain a more comfortable driving experience.
For listings with free shipping, it only applies within the continental 48 states. The engagement is harsher, but shifting faster. The race disc features a heat-treated spring steel drive plate and is well-suited for the smaller sizes in engines. The heavy duty torsional dampening springs are stronger, in most cases, than standard and provided the best sizes spring rates to suit application.
This is a 4-pad spring-centered race disc made with high quality, ceramic friction materials.
