The Action Clutch Stage 2 kit with lightweight flywheel is built for full bolt-on or low boost Si builds. It's got 110% more clamping force than the factory clutch, so it holds power without slipping, but the segmented Kevlar disc keeps the engagement smooth and predictable. The lightweight flywheel weighs about 10 pounds, which helps the engine rev faster and makes throttle response more immediate. This kit's designed for street cars that see occasional track use or spirited driving.\u003c\/p\u003e\n\n\u003ch4\u003eStage 2 Kevlar Disc, Smooth Engagement\u003c\/h4\u003e\n\n\u003cp\u003eThe clutch disc uses steel-backed segmented Kevlar friction material. Kevlar handles heat better than organic material and it lasts longer under hard use, but it needs higher clamping force to work properly. That's why the kit includes a single diaphragm heavy-duty pressure plate. The pedal effort's slightly higher than stock but it's not a heavy race clutch pedal. Engagement's smooth and progressive, so you're not dealing with the on-off grab that makes puck clutches annoying in traffic.\u003c\/p\u003e\n\n\u003ch4\u003eLightweight Flywheel, Faster Response\u003c\/h4\u003e\n\n\u003cp\u003eThe flywheel weighs about 10 pounds, which is way lighter than the factory dual-mass flywheel. Lighter flywheels let the engine rev faster because there's less rotational mass to accelerate, and throttle response feels more immediate. The tradeoff is you'll feel more drivetrain vibration at idle and low RPM. It's not a problem for most people, but if you want your Si to feel exactly like stock at idle, a lightweight flywheel's not for you.\u003c\/p\u003e\n\n\u003ch4\u003eRequires Hondata FlashPro or KTuner\u003c\/h4\u003e\n\n\u003cp\u003eYou need a Hondata FlashPro or KTuner to run this clutch and flywheel combo. The lightweight flywheel changes how fast the engine revs, and the ECU needs to be tuned to compensate or you'll get rev hang and weird idle behavior. Don't skip the tune.

That means easy driving for the first thousand miles. No hard launches, no slipping the clutch under load, no track days. If you don't break it in properly, the clutch won't grab consistently and you'll have issues.
