This kit uses the same Race Engineered SFI approved pressure plate as stage 3 daily package. The disc is designed for the special needs of a vehicle with circuit racing in mind. Kevlar friction material is used for its unique static to dynamic ratios of friction co-efficients at high energy levels. This translates to a perfect transition from one gear to the next. Discs are assembled with only performance components and equipped with torsion springs functioning as a damper between engine and gearbox.\nFLYWHEEL FEATURES Flywheels manufactured by SBC are made from low carbon, hot rolled steel that is highly resistant to warping and perfectly suited for the friction materials mated to them. Single mount CNC machining guarantees precise tolerances and perfect balance exceeding O.E. specifications. Extensive field testing has been done to determine the proper weight for each specific vehicle and to ensure smooth operation, safety and durability under extreme operating conditions. *Recommend usages are Rally, endurance race, autocross, street and daily.","images":["https://cdn.shopify.com/s/files/1/0024/4898/2060/products/169a39b4eb075d3f2943e019b6a8c6ff.jpg?v=1528354175"],"price":1237.02,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:25.947Z"},"share_url":"https://firestarter.network/l/lst_M8riegUo","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
