They do if you get them through LHT or THMotorsports. I’m assuming they have deals with CM to provide them just the disk and plate, they then build their own kit. Looks like they use portions of the OEM disk as well.

Funny you mention that. After reading earlier I looked to see if CM sells just their pp, and yup, you can only buy it in a kit.
ACT HD and OEM disk is king for most people within the 400-500whp range @ or slightly above 300 ft/lbs of torque, and that's where a lot of people like to stay. Can't wait to get mine installed and give impressions on it. According to THMotorsports testing, the ACT and CM PP is virtually identical in clamping force. They said roughly 2400 lbs for the CM PP, and 25-2600 for the ACT. In terms of pedal feel it's all subjective....not seeing how the CM PP can achieve the same clamping load with less force required and replicate the feel of an OEM PP which has roughly 6-700 lbs less clamping force @ 1870 lbs. I'd imagine the ACT + OEM setup feels similar to the CM in essentially every way minus the buzz.
The only real concerning factor for most people should be the cost. The ACT + OEM disk & bearing setup is quite a bit more expensive vs. buying the FX300 kits with a Nachi bearing already included. I think the money is well worth it. @hecash on here said he was running the ACT & OEM disk combo for years @ 400whp and when he went to replace the disk as preventative maintenance the friction disk was still almost within "new" tolerance....Can't go wrong imo.

I assume we could run a Spoon OEM style disk with the ACT PP as well? Thinking of this as an option because a) Spoon and b) Spoon said it holds more torque than OEM.

They got so many clutch installs videos though and I can't find it now

Running the CM FX300 kit, with OEM bearings and Honda Grease. Feels lighter and smoother than my OEM one that came out at 30K miles. It almost feels like I didn't bleed the clutch line properly but I did, and she fully engages and disengages fine, loving the light pedal feel!

but as far as pedal feel. I feel like the engagment point is sooo much higher now than it used to be. I dont have an on/off feeling, but i gotta let out the pedal a good 50% more than I used to when applying gas to get the car moving. Is this normal for a new clutch? maybe my engagment point felt so much lower in the pedal travel before, because it was older? I dont know whats expected but its a big difference. So now at stop lights i have to completely re-train my leg to allow the pedal out more before giving it gas. Its just not as smooth as it was/I'm used to. ALMOST on/off like some have mentioned.
I've got no clutch fluid leaks, and the resevoir is full. So I dont think anything is bothered there. But could I benefit from a bleed? or does the pedal some how need to be adjusted?
Note: prior to this install was 100% oem, 96k miles and it felt, to me, fine. I only had it replaced beacuse tehy fixed the rear main seal and dit he clutch for me while they were in there.

Glad I foudn this thread. LHT installed my clutchmasters FX300 and new flywheel. I got the buzz too. Now that I know that is normal I'm okay with it.
