In most cases clutch shudder will be experienced which is why this style of clutch is not recommended for daily driven vehicles NPC Performance Clutches are an Australian based, family owned business dedicated to producing high quality, high performance clutches to suit all needs - from daily drivers to heavy towing, and track or race cars.
