OS Giken Mitsubishi LANCER EVO 1-3 CE9A STR Series Twin Plate w/Soft Diaphragm Clutch

The twin-plate clutch design in this OS Giken STR Series unit utilizes a soft diaphragm spring, a key feature that helps manage engagement for a more predictable feel, especially important when you're pushing your Lancer Evo 1-3 CE9A hard. This isn't just about holding more power; it's about making that power usable through the drivetrain. OS Giken is well-known for their high-performance clutch systems, and this twin-plate setup is built to handle significant increases in torque and horsepower that often come with modified Evo engines.

Constructed with durable friction materials and robust pressure plates, this clutch is designed for longevity under demanding conditions. The twin-plate configuration offers a larger friction surface area compared to a single-plate clutch, which is crucial for dissipating heat effectively and preventing premature wear. This improved heat management means the clutch can withstand repeated, aggressive engagement without fading. The soft diaphragm spring is engineered to provide a smoother engagement point than a standard, stiffer diaphragm, making it more manageable for daily driving or spirited track use without sacrificing holding capacity.

When installing a performance clutch like this, it's important to ensure all related drivetrain components are in good condition. This kit is designed as a direct replacement for the stock clutch assembly, but professional installation is highly recommended to ensure proper alignment and setup. This ensures you get the most out of the clutch's performance capabilities and its intended engagement characteristics.
