Zestaw sprzęgła Xtreme Clutch Nissan PATROL 4.8 180KW (2000-on) - KNI30001-1R - The sprung ceramic clutch kits use an upgraded pressure plate combined with a ceramic friction disc in sprung configurations. This clutch kits range is designed for race / track going vehicles that require a higher torque capacity and temperature tolerance, and faster engagement. Clutch engagement is more aggressive than organic kits, so it is not recommended for daily driven vehicles. These kits feature a high quality cover with increased clamping force compared with standard, between 75-120% depending on the demands of the individual vehicle. The covers have an anti-burst pressure plate casting, The material is SFI certified for racing use- burst proof to 14,000rpm. So combining a â€1R’ kit with Xtreme Performance flywheels also massively improves the safety level for cars. They use a ceramic “paddle” friction disc which can result in more noise and harsher engagement and is mainly suited to high speed 4x 4 trial or desert race.
