The WRX STI isn't just a car; it's a platform for self-expression. The vast aftermarket support for this model allows owners to personalize their rides to their individual tastes and performance aspirations. From subtle tweaks like engine tunes and suspension upgrades to bolder modifications like aerodynamic enhancements and performance exhaust systems, the possibilities are endless.

For true driving aficionados, few things compare to the satisfaction of mastering a manual transmission. The WRX STI's 6-speed manual gearbox delivers a visceral connection between driver and machine, allowing you to orchestrate gear changes with precision and feel the car respond to your every command. This interactive experience is something that modern automatics, while offering convenience, can simply never replicate.

Although no longer in production, the legacy of the WRX STI lives on in the hearts and minds of countless automotive enthusiasts around the world. Its impact on the automotive landscape is undeniable, and its influence continues to inspire future generations of performance cars. The WRX STI may be a product of a bygone era, but its appeal transcends time, offering a driving experience that is both exhilarating and rewarding. For those seeking a true driver's car, one that demands engagement and rewards skill, the WRX STI remains an icon of the automotive world.

Why Would You Need an Upgraded Clutch?

With any power modifications installation of an upgraded clutch should be considered. You'll get a performance boost as well as unique, race-inspired shifting that sets your car apart from every other stock version on the road. Performance clutches hold higher torque capacity with better engagement and faster shifting.

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-Unique combinations of Organic and Cerametallic friction materials combine to produce increased torque capacity, while maintaining excellent drivability. The result is a higher torque capacity than a stage 1 kit, and better drivability than stage 3 kit. The stage 2 kit offers a high torque capacity cover assembly, plus a Spheroidal Graphite (SG Iron) casting with ER² Technology for maximum strength and higher torque capacity. The clutch disc features an organic friction material on the ER² pressure plate side of the disc, combined with cerametallic friction material 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.
