Spec 17-21 Honda Civic Si 1.5T Stage 3 Plus Clutch Kit

The Stage 3 Plus clutch kit from SPEC uses a unique sprung hub design for the disc, which helps absorb some of the shock and vibration that can come with a high-performance clutch. This is a well-built setup designed for the 2017-2021 Honda Civic Si with the 1.5T engine, aiming to handle more power than the stock clutch can manage.

This kit includes a heavy-duty pressure plate, a sprung disc featuring a high-performance friction material, and a pilot bearing. The sprung disc is key here; it uses internal springs to cushion engagement, making it a bit more streetable than a solid hub disc while still offering a strong grip for spirited driving or track use. SPEC builds these kits to be a solid option when you're looking to upgrade your Civic Si's drivetrain to handle increased horsepower and torque, whether from engine modifications or just pushing the car harder.

When installing this clutch kit, it's important to follow the manufacturer's instructions carefully. Ensure the flywheel is properly resurfaced or replaced, and that all mating surfaces are clean. This kit is a direct replacement for the factory clutch components, but it's designed for a higher performance threshold. It's a significant upgrade for owners who want a clutch that can keep up with their driving style and engine modifications.
