Spec 87-92 Supra Turbo Stage 5 Clutch Kit - Unsprung Race Use ONLY

This SPEC Stage 5 clutch kit, part number ST635, is built for the demanding needs of racing applications in your 1986-1992 Toyota Supra Turbo. It features a rigid, unsprung hub design, which means there are no dampening springs. This direct connection between the engine and transmission helps ensure immediate engagement and maximum power transfer, crucial for competitive track use where every millisecond counts. The unsprung nature also contributes to a more robust feel under hard acceleration.

The Stage 5 designation indicates this kit is engineered for high-horsepower, high-torque setups, often found in modified Supras pushing significant power. It includes a high-clamping force pressure plate designed to hold the engine's power under extreme conditions, preventing clutch slippage. Paired with a performance friction disc, this kit offers a substantial increase in holding capacity compared to stock. Because it's unsprung, expect a more direct and potentially abrupt engagement feel, which is typical for race-oriented clutch systems. This kit is not intended for daily driving or street use due to its aggressive engagement characteristics.

When installing this clutch kit, it's important to note that the unsprung design requires careful clutch pedal modulation. It's recommended to have a professional mechanic perform the installation to ensure proper alignment and break-in procedures are followed. This kit is designed for maximum performance and durability in a racing environment, making it a solid choice for serious track enthusiasts looking to handle substantial power upgrades.
