From 1978 to 2020, Holden produced the Commodore, a large family car. It was produced in Australia from 1978 to 2017 and in New Zealand from 1979 to 1990, with production of locally manufactured versions in Australia ending on October 20, 2017. The Commodore was produced until 2020, when the Holden brand and nameplate were completely phased out. The Ford Falcon was a major rival. Prior to the second generation Commodore, which debuted in 1988, Holden was a full class below the Falcon. Holden’s largest export programs involving Commodore and its derivatives began with the introduction of the third generation in 1997. Holden was sold as a Chevrolet in the Middle East, South Africa, and Brazil. In North America, high-performance export versions were sold as Pontiac and later Chevrolet. HSV is also known as Vauxhall in the United Kingdom, Chevrolet Special Vehicles (CSV) in the Middle East, and HSV in New Zealand and Singapore.
The Mantic Stages Clutch System comes in a variety of configurations:
Stage 1 – This kit is developed primarily for the street performance niche, with more torque capability and better heat dispersion than the OE. The organic clutch disc has a high torque capacity cover, SG Iron ER2 grooved pressure plate, and SG Iron ER2 grooved pressure plate.
Stage 2 – A combination of organic and cerametallic friction components boost torque capacity while maintaining excellent driveability. As a result, the torque capacity is greater than that of a stage 1 kit, and the drivability is better to that of a stage 3 kit. The stage 2 package includes a high torque capacity cover assembly as well as a Spheroidal Graphite (SG Iron) casting with ER2. Maximum strength and torque capabilities are provided by this technology. Organic friction material is used on the ER2 pressure plate side of the clutch disc, whereas cerametallic friction material is used on the flywheel side.
Stage 3 – Performance Clutch Systems for street use require increased torque capacity while retaining good pedal feel with fine modulation control. These characteristics inevitably increase heat which reduces service life. So the ideal performance clutch system for the street must also have improved heat dissipation. Mantic Stage 3 clutch kits feature a 20% increase (over original equipment) in clamp load for increased torque capacity. Approximately 300% stronger than a standard casting this material (sometimes referred to as an Anti Burst casting) not only increases strength by up to 3 times, it also improves heat dispersion. To insure that the clutch system performs at maximum efficiency and that no unwanted vibration is generated as the cover spins, all Mantic Stage cover assemblies undergo a 2 stage balancing process. The Torque Capacity of a Clutch Plate can be increased by using exotic cerametallic friction material featuring a higher coefficient of friction. However, cerametallic material reduces pedal feel and results in more sudden clutch engagement, reducing street driveability. Mantic Stage 3 Clutch Kits feature cerametallic friction material on both sides of the clutch plate. This results in a strong torque capacity increase compared with Stage 2 – but reduced street driveability. Stage 3 kits include cushioned segments and a sprung hub to maintain a reasonable level of street drivability.
Stage 4 – Capable of handling a lot of torque, this system isn’t intended for street use. The cover assembly has a high torque capacity, an SG Iron pressure plate, and a sprung center cerametallic disc.
Stage 5 – Our most aggressive single disc application, is intended specifically for track and motorsport applications. The stage 5 kit includes a high torque capacity cover assembly with an SG iron burst-proof pressure plate, as well as a rigid hub and undamaged Cerametallic Clutch Disc.
Mantic Stage Series Mantic Stage 1 and Stage 2 clutch kit cover assemblies feature the patented ER² Groove Design, which is a unique pattern CNC machined on the friction face of the pressure plate. This groove has been specifically designed to increase the Mean Effective Radius of the pressure place and assist in heat dissipation. The increase in the Mean Effective Radius of the cover assembly gives a significant increase in the torque capacity.
