In a manual transmission, the Clutch Kit and Flywheel act as the “bridge” between the engine and the gearbox. They allow you to disconnect the engine’s power so you can change gears or come to a stop without the engine stalling.

• • Woven Organic: The standard for daily drivers. It contains copper or brass wire woven into the material for strength, offering the smoothest engagement.

  • Kevlar: Used in high-mileage or off-road vehicles. It lasts 2–3 times longer than organic material but requires a strict 1,000-mile “break-in” period

  • Cerametallic (Puck Style): Found in race cars. Instead of a full circle, it uses “pucks” to increase pressure per square inch. It grabs instantly but can “chatter” in stop-and-go traffic.

  • Sprung Hub (Dampening): Most street discs have 4 to 8 heavy-duty coil springs in the center. These act as shock absorbers, soaking up the “thumping” of the engine’s power strokes to prevent transmission gear rattle.

  • Segmented Facings: High-performance discs often have gaps between the friction material segments. This allows heat to escape and prevents the disc from “warping” under heavy use.
