Competition Stage 2 Clutch Kit competes head to head with the ACT Street Clutch Kit that we also offer. After testing both, we're comfortable offering both here at Unity Performance. You can read our impressions on the ACT Kit on it's product page, here's our thoughts and description
of the Competition Clutch Stage 2 Kit w/ the 22lbs Single Mass Flywheel.
The Competition Clutch Stage 2 Kit shaves 10lbs from the Factory design by going with a lighter Single Mass Flywheel design compared to the heavy Dual Mass Flywheel that weighs in at over 32lbs on the Civic 1.5T and Si. This weight loss contributes to elimination of rev-hang, which we know plagues the manual shifting experience with stock clutch kits. The stronger pressure plate and clutch disc from Competition Clutch are able to hold 425ftlbs of torque in total, which is good for any FBO and larger turbo build that you could do on a stock engine.
The 22lb Lightweight Flywheel is more daily friendly than the 17lb Ultra Lightwieght Competition Clutch Flywheel, and the ACT Single Mass Flywheel which is also 17lbs. Going with 17lbs you do get even less Rev Hang, but you can't be lazy with your clutch and gas pedal balance in 1st and Reverse, otherwise you'll stall. In the forward gears, the 22lbs Flywheel is also smoother between each shift.
During the first 500 miles of break-in period, the Competition's clutch pedal feel is very stiff/heavy, but it lightens up after the break-in, and will feel like a stock Civic Type R clutch pedal which has good weight to it.
Feel free to ask us any questions, this is a product we can stand behind!

It's no secret that clutch kits have been a hit or miss (mostly miss) on the Civic 1.5T platform, hence we did not offer one until now till we did our own testing to verify what works well rather than selling a hotly anticipated item early, and finding issues later.
Having broken-in carefully at first, then all sorts of daily driving, performing several WOT pulls, and even two full track days on the ACT HC10-HDSS Kit, we are confident after 3,000 miles of use that this clutch kit will perform well on your 2016+ Honda Civic 1.5T with the Manual Transmission. The clutch pedal is mildly stiffer than the factory feel; solid engagement but not heavy enough to call it a "leg day" type of clutch. The less rotating inertia from the 17.6lbs flywheel (32.5lbs factory flywheel) means that revs rise up, and drop much faster, making this engine a lot less lazy, and more lively!
No chatter to report, and rev hang has been completely eliminated. ACT does have other 4 and 6-puck clutch kits, which we're choosing not to offer yet since they are race kits with shorter life span that are tricky to drive daily, plus we haven't tested that kit. Our Blue Si is FBO and puts power down with ease, and we have seen others in the community running big turbo setups with this kit, and don't have any issues.
Here's what's included in the box
- ACT 17.6lbs Single Mass Aluminum Flywheel (factory flywheel is a Dual Mass 32.5lbs unit)
- ACT Full Face Sprung Clutch Disc
- ACT Pressure Plate
- Alignment Tool
- Pilot Bushing
- Release Bearing
- Instructions
Specs:
- Total Weight: 33lbs
- Torque Capacity: 363ft/lbs (63% better than factory)
- Disc Material: Organic
Check out all our pictures of the kit being weighed and installed.
On our Blue Si, this kit is paired up with the upgraded Clutch Master Cylinder (KzCMC), and PRL SS Clutch Line - Clutch Delay Valve (CDV) Delete also performed. Although it is NOT a must to perform either of these upgrades/modifications, however IF you will be racing, and trying to shift quickly at redline then you may encounter what is known as "Lockout". It has been well-documented that the factory components may lead to a lockout situation, not letting you shift as fast as you desire. "Lockout" is not the clutch kit's fault, it's the factory Clutch Master Cylinder that may struggle to generate enough hydraulic pressure to engage and disengage ANY heavy duty clutch quickly. You can still run this kit without those upgrades if you so choose to do so, it will not harm your clutch kit either way.
We are still using the ACT Throw-out Bearing with our Si that is included in the kit, and for warranty purposes it MUST be used. Some will prefer to use the OEM Throw-out bearing, that would be your choice but please understand that it may complicate any warranty matters since ACT states that all their components must be used.
