Using this ACT performance street disc is straightforward. Just install it as you would with a regular clutch disc in your Mazda 3 Mazdaspeed (2007 - 2013) or Mazda 6 Mazdaspeed (2006 - 2007). When shifting gears, you'll notice the quick and smooth operation. As for maintenance, check the disc regularly for wear and tear. If you notice any abnormal noise or a decrease in shifting performance, it might be time to have it inspected. Also, keep it clean and dry to ensure its long - term performance. Don't overload the clutch during driving, as it can reduce the disc's lifespan. With proper use and care, this disc will serve you well for a long time.
