Review ACT Heavy Duty Race Clutch Kit Mazda fits MIATA MX-5 2006–2012

Introducing the ACT ZM4-HDG6 6-Pad Race Clutch Kit, specifically designed for Mazda MX-5 Miata models from the years 2006 to 2012. This high-performance clutch kit is engineered to deliver superior clamping force, durability, and responsiveness for those seeking to extract maximum power and performance from their beloved Miata.

The heart of this kit is the 6-pad design, which employs a unique friction material composition that offers excellent bite and release characteristics. The organic friction material used in the clutch disc provides a smooth engagement, while the 6 heavy-duty, high-clamping pressure steel pressure plates ensure exceptional holding power. The pressure plates are also vented to minimize heat buildup and reduce the risk of warping, ensuring consistent clamping force throughout the life of the clutch.

The flywheel in this kit is a high-performance, solid aluminum design, which not only reduces rotational mass for faster revs but also dissipates heat more effectively than a stock cast iron flywheel. This results in improved power delivery and increased engine responsiveness.

The ACT ZM4-HDG6 Race Clutch Kit is designed for use with a lightweight, performance-oriented flywheel, so it does not include a stock-style heavy flywheel. The kit also includes a new release bearing, clutch alignment tool, and all necessary hardware for a straightforward installation.
