Product Description

The Competition Clutch 8091-STU-2100 Stage 2 Street Series Clutch Kit with ultra-lightweight flywheel is a direct performance upgrade for Honda Civic Si 1.5 L turbo vehicles from 2017-2020 and 2022-2023. Designed to handle approximately 80 % more torque than the stock clutch, this kit delivers confident engagement and strong holding power for spirited street driving and occasional track days. The larger 240 mm clutch disc provides additional surface area for improved durability under power, while the organic Brass Plus material ensures smooth engagement with reduced chatter and pedal effort.

The included ultra-lightweight steel flywheel (~17 lbs) lowers rotational mass, improving throttle response and making the engine feel more responsive during acceleration and deceleration. With the full kit - including pressure plate, throw-out bearing, pilot bearing/bushing, alignment tool, and hardware - installation is convenient and complete. This clutch upgrade is ideal for drivers who want a balance of daily drivability and enhanced performance without going to a full race-spec setup.
