The ACT ZX5-HDR4 is a top-tier choice for performance enthusiasts seeking a reliable and robust clutch solution. This Heavy Duty pressure plate is designed with an exclusive diaphragm that not only increases clamp load but also reduces deflection, ensuring maximum clutch longevity. The four-stage heat-treating process that each diaphragm undergoes guarantees exceptional performance under stress, making it an ideal option for those who push their vehicles to the limit.
“I installed the ZX5-HDR4 in my Mazda 3, and the difference is night and day! The shifts are quicker, and I can really feel the power transfer. Just be ready for a bit of a harsher engagement, but it's totally worth it!” - Jason R.
“This clutch kit has transformed my driving experience. I love how it handles the power, and the pedal feel is surprisingly manageable. Highly recommend for anyone serious about racing!” - Linda K.
