This Sport/Race Sprung 4 Pad Kit is designed to elevate your driving experience with its robust features and reliable performance. Customers have noted a noticeable improvement in their vehicle's responsiveness and shifting speed after installation, making it a favorite among both casual drivers and racing aficionados.
The HA3-SPG4 kit showcases a specially engineered Sport pressure plate that enhances clamp load while minimizing deflection. This means you get a clutch that not only lasts longer but performs better under pressure. Each diaphragm undergoes a meticulous four-stage heat-treating process, ensuring that you receive unparalleled performance and durability. The precision cover stampings used in ACT pressure plates contribute to their rigidity and consistency, which is crucial for maintaining performance under demanding conditions.
One of the standout features of the HA3-SPG4 is its 4-pad spring-centered race disc. This design effectively dampens torsional vibrations, leading to a quieter operation while resisting failure, even in the most challenging environments. Users have reported that while the engagement might feel harsher, the trade-off is faster and more precise shifting, which is particularly beneficial for those who enjoy spirited driving.
