Action Clutch Stage 3 Clutch for 12-15 Honda Civic Si

Action Clutch Stage 3 Clutch Kit - 2012-2015 Honda Civic Si / 2013-2015 Acura ILX

Pushing more power through your Si or ILX than the stock clutch wants to handle? The Action Clutch Stage 3 is the step up. This is the 1MS sprung MIBA ceramic kit, and it clamps down with about 170% more holding capacity than your factory clutch, so it hangs onto a built bolt-on car or a mild power adder without slipping. Here's what makes it the sweet spot for a lot of Si owners: it's built for heavy-duty street use with the occasional drag pass or road course thrown in, so it'll still daily drive while holding up to the abuse when you go have fun. You can grab it on its own or paired with a lightweight flywheel, depending on how far you want to take it.

What's Doing The Work

The heavy-duty single diaphragm pressure plate and reinforced drive straps are what put the extra clamping force down and keep it there, and the sprung MIBA ceramic disc is what gives you that quicker, firmer engagement. You can spec the disc as a 4-puck or a 6-puck depending on the feel you're after. Add it all up and you've got a clutch that holds 170% more than stock and shrugs off heavy street duty plus the occasional track or strip day without giving up on you.

Real Talk On Living With A Ceramic Clutch

Let's set expectations the honest way, because a ceramic disc behaves differently than the stock clutch you're used to. It engages quicker and firmer, and right after install it's going to chatter some, that's normal for a sprung ceramic, and it settles down a lot once you've properly broken it in. The other thing to understand: ceramic is about holding capacity and durability, not about lasting longer than a stock clutch. If you ride it and slip it constantly in stop-and-go traffic, you'll wear it out faster, because the harsher engagement and all that slipping is hard on the material. Drive it with a little intention, get on and off the clutch cleanly, and it'll reward you. This is a performance clutch that happens to be street-friendly, not a stock replacement that disappears into your commute.

With Or Without The Lightweight Flywheel

You've got a choice here. Run the kit with your existing flywheel (get it resurfaced so the new disc has a clean surface to bite), or add Action Clutch's lightweight flywheel and wake the car up even more. A lighter flywheel lets the engine rev quicker and makes the car feel more eager and responsive, which is a blast on a sporty K24 car like this. The trade-off is it'll add a touch more chatter at idle and take a slightly more deliberate foot to launch smoothly. If you're chasing response and you don't mind a little more character, the flywheel combo is the move. If you'd rather keep it simple, the kit on its own still gets you the holding capacity.

Break-In Is Mandatory, Don't Skip It

This part matters for your warranty and for how the clutch holds up, so do it right. Your break-in is 500 street miles, and during those miles you keep the RPM under 4,500, stay at half throttle or less, and run no boost if your car's boosted. That break-in is what lets the disc and flywheel surfaces mate properly, and Action Clutch requires it to keep the warranty valid and to get the full holding capacity and longevity out of the kit. Rush it and you can glaze the disc and cost yourself the grip you paid for, so be patient for those first 500 miles.

The Safety Stuff Action Clutch Doesn't Skip

This matters more than people realize. When a clutch spring works loose inside the bellhousing, it can do catastrophic damage to your engine or transmission. Action Clutch designed their patented fully enclosed spring retainers specifically to keep those springs locked in place so that doesn't happen. And every kit gets inspected and signed off by one of their engineers before it ships, a team with over 60 years of combined experience, so the clutch going into your car was checked by someone who knows exactly what they're looking at.

Note: Action Clutch Stage 3 (1MS) sprung MIBA ceramic clutch kit for the 2012-2015 Honda Civic Si and 2013-2015 Acura ILX. Includes a heavy-duty single diaphragm pressure plate with reinforced drive straps and a sprung MIBA ceramic disc, available in 4-puck or 6-puck, and offered with or without an Action Clutch lightweight flywheel. Provides roughly 170% more holding capacity than the factory clutch, rated in crank torque rather than wheel torque. Built for heavy-duty street use with occasional drag or road racing. A sprung ceramic disc engages quicker and firmer and will chatter until properly broken in. Ceramic increases holding capacity and durability rather than extending clutch life, and constant slipping in stop-and-go driving can cause premature wear. Break-in is required: 500 street miles, RPM kept under 4,500, no more than half throttle, and no boost (if applicable), which is necessary to retain the warranty and ensure full longevity and holding capacity.
