What is the primary benefit of a Stage 4 clutch kit?

A Stage 4 clutch kit offers significantly increased holding capacity for horsepower and torque compared to stock or lower-stage kits. This makes it ideal for heavily modified vehicles that experience high stress on the drivetrain, such as those used for track days or aggressive performance driving.

What should I expect regarding pedal feel and engagement with this clutch?

You can expect a firmer pedal feel and a more abrupt engagement with this Stage 4 clutch compared to a stock clutch. The sprung disc helps to mitigate some harshness, but it is a performance-oriented setup designed for maximum power transfer.

What other parts should be considered when installing this clutch kit?

It is highly recommended to inspect or replace associated drivetrain components during clutch installation. This includes the pilot bearing and release bearing, as well as ensuring the flywheel is in good condition or resurfaced/replaced as needed for optimal performance and longevity.

About this part

Product Details

If you're looking to significantly upgrade the performance of your 2013-2014 Ford Fiesta ST with the 1.6L EcoBoost engine, this SPEC Stage 4 Clutch Kit is a serious consideration. This kit is built to handle much higher horsepower and torque than the stock clutch, making it suitable for modified vehicles that see frequent track use or aggressive driving. It’s designed to be a direct replacement for your factory clutch assembly, but with substantially increased capacity.

The Stage 4 kit from SPEC includes a sprung, multi-plate disc assembly that offers a very high clamping force, which is essential for transferring increased power to the drivetrain without slipping. The sprung design helps to dampen some of the engagement harshness that can come with a high-performance clutch, though it's still a firm engagement. This kit is a well-built option for those pushing the limits of their Fiesta ST's powertrain. It’s important to note that with a Stage 4 clutch, you can expect a firmer pedal feel and a more abrupt engagement compared to stock, which is a trade-off for its increased holding power.

When installing a clutch kit of this caliber, it's always recommended to have a professional mechanic perform the work, as it requires dropping the transmission. Ensure that all associated components, such as the pilot bearing and release bearing, are in good condition or replaced concurrently to ensure optimal performance and longevity of the new clutch system. This kit is intended for vehicles that have undergone significant engine modifications and require a clutch that can reliably handle the added stress.
