The heavy - duty torsional dampening springs are stronger than standard ones, sized and rated to best suit your vehicle. This disc is ideal for larger clutch sizes as it can absorb more heat and provide smoother engagement. You'll experience an aggressive feel with quick shifts and mild to moderate gear rattle. It's highly recommended for high - horsepower street driving or racing. Compared to typical organic materials, it has high burst strength and can hold 28% more torque.

Using this ACT 6 - puck sprung replacement disc is straightforward. First, make sure your vehicle is the 2004 - 2021 Subaru STI or 2007 - 2009 Subaru Legacy GT Spec B as it's specifically designed for these models. When installing, follow the standard clutch replacement procedures. Since it has an aggressive engagement, be prepared for a different driving feel compared to a regular clutch. For high - horsepower street use or racing, this disc will perform great, but expect a bit of gear rattle. As for maintenance, regularly check the clutch for wear. If you notice any abnormal noises or a change in shifting performance, it might be time to have it inspected. Also, keep the clutch clean and free from debris to ensure its longevity.
