Spec 05-06 tC / 99-02 3.0L Solara Stage 5 Clutch Kit : Unsprung Race Use ONLY

SPEC is known for making well-built drivetrain components, and this Stage 5 clutch kit, part number ST825, is a prime example of their commitment to performance. This kit is specifically designed for race applications and features an unsprung hub, meaning it offers a very direct and aggressive engagement. It’s built to handle the demands of high-horsepower engines and intense track use where quick shifts and maximum power transfer are critical. This clutch is not intended for street use due to its aggressive nature.

The Stage 5 clutch kit includes a high-performance pressure plate, a sprung or unsprung race disc (this specific model is unsprung), and a release bearing. The unsprung design means the clutch disc doesn't have any dampening springs, which contributes to its firm engagement and ability to withstand extreme abuse. This setup is ideal for drag racing, road racing, or any motorsport where durability and immediate power delivery are paramount. It’s important to note that this clutch requires a firm pedal feel and can be challenging to modulate at low speeds, which is why it's strictly recommended for race use only.

This clutch kit fits a range of vehicles, including the 2005-2006 Scion tC, 1999-2004 Toyota Solara (specifically the 3.0L models), and various Toyota Camry models from 1994-2001 and 2005-2006. It also fits the 2004-2005 Toyota RAV4 and 1990-1993 Lexus ES250 and 1992-1993 Lexus ES300. Because this is a race-specific component, it’s crucial to ensure your vehicle’s drivetrain can handle the increased power and torque this clutch is designed to transmit. Proper installation and break-in procedures, as recommended by SPEC, are essential for optimal performance and longevity in a racing environment.
