ACT Street Discs are designed for smooth engagement, quiet operation and improved durability using only the best organic, spring center designs.
When a special ACT Performance Organic Street Disc is available, the suffix "SS" will appear. These discs use special steel backed performance linings designed to withstand high heat and abuse. Most of these "SS" discs are also modified for quicker shifting.
What is all the hype about different lining materials available? ACT still contends that nothing can beat a good quality organic disc for street use. Virtually all the premium sport car manufacturers use organic discs.

|Q?||Do ACT clutches require a break in period?|
|A:||For organic street discs "00 and SS" we recommend breaking in the clutch for 200-300 miles with mild engagement such as stop and go city driving prior to racing or spirited driving. ACT race discs usually only require a few hard slips to lap in the surfaces prior to normal driving or racing. Do not overheat the clutch during the break in period.|
