06-11 & 12-15 Honda Civic Si EM1 Nissin CMC & Stainless Steel Clutch Line Upgrade
HARDmotion K-Series EM1 CMC & HD Slave Kit V2.0 "2nd gear grind fix"
The HARDmotion 06-11 / 12-15 Civic Si & Acura RSX EM1 CMC & Stainless steel clutch line kit. The kit starts with a OEM Nissin EM1 CMC, the reason for this unit is two things. One the nissin em1 is the most prooven and reliable cmc you can install on your car. They last and wont fail on you like other units can. Two it doesnt have any delay valves built into it and thats the core reason for switching to this unit. This allows the clutch pedal to engage and disengage the transmission at the optimal speed so grinding wont incur. The CMC is then fitted to our upgraded stainless steel clutch line and that comes with all fittings needed to adapt the line. This clutch line is also a step above most with a stainless steel clutch line, that is a heavy duty unit thats built to last along with a rubber coating (to prevent dirt from the engine bay getting into an exposed steel wrap and wearing it or bursting it).
Finally we round out our kit with the new HARDmotion Slave Cylinder, this is the final piece to the puzzle of fixing any grind issues. The main piece that connects to the transmission is the slave. As our vehicles age the stock cmc and slave become worn and need replacing and they dont function as well. Thats why we now suggest getting our upgraded k-series slave cylinder. This unit not only is built to last as well but doesnt contain any delay valves. Yet again the main purpose of any hope of fixing your shift is removing the delay valves. This unit was built totally with that and mind and was built without any delay valve. Upgraded all around for performance.
With all of this combined you will enjoy proper shifting, engagement and release of the clutch, even under high rpm aggressive driving where it really counts. Not only that but this helps protect your transmission and synchros.
"If you are grinding any gears, having difficulty shifting, slow shifts or get completely locked out during a high rpm shift. This is the solution." -- HARDmotion Team
How does it work? The factory has two delay valves in the cmc and the slave. We use a cmc and slave that are high quality long lasting and that do not contain these delay valves. The delay valves in the oem units are built to make the clutch pedal less dramatic when it grabs. The drawback is the transmission and clutch do not disconnect fast enough at high rpm with the oem units and you get a grind. With our upgraded units as a system it allows the clutch to disengage properly and quickly (just like honda used to make it) why we are using a em1 cmc and our own slave unit which are built to function properly and alleviate the grinding issue and increase the overall performance and feel. These units once installed made a dramatic difference on every car we have tested it in personally. We have dealerships who use this on customer cars and honda certified master techs who also agree this solution works. We have sold over 300+ units and we constantly get recommendations as the best kit out.
Why choose our kit over others? Our kit is way more affordable than our competitors and comes with the same if not better parts + free shipping. Your saving over $50 dollars and getting a higher quality SS line at the same time and you get the proper parts and slave that complete the system as a whole. The problem is most people just do the CMC only, when the slave is the actual final piece that connects to the trans. If one or the other isnt working and isnt working fast you will get grinds. The other reason to choose our kits, is they just dont fail. They just literally dont and we guarantee and back it with a no hassle warranty.
We guarantee it will work!: You wont find this anywhere else and backed with a satisfaction guarantee. If it doesnt work, we will refund your money in full.

Installation Help: The EM1 CMC basics you need to know.
1. The HARDmotion EM1 clutch master cylinder (cmc) needs to be taken apart. From there upon uninstalling your stock CMC.
2. Take apart your your stock clutch master cylinder internals inside the HARDmotion em1 housing.
3. Swap over most importantly the rod from your oem cmc to the HARDmotion em1 cmc. View diagram below.
4. Here is a diagram below on one way to install the guts of the new HARDmotion EM1 CMC. You are swapping the rod, nut and bracket over.
5. Once your new HARDmotion CMC is assembled. Reinstall into vehicle.
6. Stainless line will attach to the EM1 Via the right angle, the other straight line connection goes to the slave unit.
7. Bleeding. You are receiving a dry brand new nissin CMC, the same that honda uses for the OEM vehicles. You may have trouble bleeding or getting pedal pressure the first time. What you need to do which a lot of people are successful with is "bench bleed" the cmc.
This information is all over the internet with videos and tutorials on how to do so. Another method is using a vaccum bleeder.
8. Once complete test free play and ensure that there is about 1 inch of freeplay. Freeplay is the pressureless zone of the clutch pedal to where its easy to press down before it starts to stiffen where engagement starts. This is important so your clutch can properly disengage.
How hard is it?: Everyone has been able to install this item themselves. It can take from 1-2 hours if proper preparation and bleeding is done.
Final Notes: Be sure to watch youtube for diys on this mod, even videos. Simply searching "diy em1 cmc install" usually pulls up lots of pages which will help assist you.
We know there are many ways to go about it, so we allow you to find what works best for you. Just be sure to take your time with understanding and bleeding the system and knowing to swap the internals beforehand. This job is very similiar to a cmc and slave install and reinstall. Also the stainless line makes it easier to install.

Lately i was having issues with my shifting..hard to get into gears and grinding issues especially 2nd and 3rd gears at high rpm..did my reviews and homework i decided to get the em1 cmc combo with hd slave instead of ktuned cmc and slave..heard alot of bad reviews about ktuned cmc and slave and by far this is the best decision i’ve made..smooth clutch, shifting is awesome and bye bye grinding..i recommend this product to all 06-11 civic si owners!!
YOU NEED TO BUY THIS

This is exactly what I was looking for. Installed the K-Tuned CMC and Slave back in 10/2017 and noticed it was a little heavy when engaging (assumed this was normal). Last month I noticed I was slowly having issues putting the car into gear. Last week the CMC completely failed and had to get my vehicle towed to my local garage. After hours of research, I rolled the dice and bought this kit hoping the issue was the CMC. Sure enough it was! The car 10x better than with the K-Tuned setup. I would stay away from the K-Tuned version as its been reported through numerous of internal seal failure. Highly recommend this product for both quality and price.
Great product and service!

Paired this with the hardmotion hd slave on an exedy stage 1 with chromology lightweight flywheel and it is just perfect. After the pain of installing and bleeding the system I am all smiles. Zero issues and better fitment than exedy oem part and line.

Je suis heureux d'avoir choisi Nissin CMC et acier inoxydable Honda Civic Si EM1+ Cylindre esclave HD HARDmotion !
Au début j'ai remarquer qu'il était fait pareil comme l'original , mais heureusement qu'il n'a pas de délais dans le Cylindre HARDmotion . Maintenant je change de vitesse a froid au chaud sans endommagé ma transmission .
Je recommande HARDmotion !!

Ever since installing this cmc my car has had no issues at all!! Highly recommend ordering this along with the slave cylinder.

The 99-00 SI CMC is an awesome upgrade to get for your 8th gen civics, I recommend getting the hard motion slave with it as well, since installation I have not grinded a single gear! installation is a pain but well worth it! My civic is my daily I live in a city where my commute is 45 minutes of stop and go traffic and I have not lost any pressure. Pedal feel is great no complaints at all!
So job well done by HARDMOTION, This is a must if you plan on building or even do some spirited driving on the weekends!
