Is this normal? I don't mind the vibration I just want to be certain I'm not damaging any of the components.
Hi Rambo,
I'll reply here so everyone can get the answer. No, it's not possible for your clutch to be stuck partially engaged with the RJM pedal. That is only an issue with the oem pedal doing that. There will be more clutch feedback thru the pedal now as the RJM pedal transmits more feel of what the clutch is doing, not a numb and disconnected feeling like stock. These vibrations were always there, just being masked by the stiff oem assist spring that was dampening them. When you start driving it you'll immediately notice more feedback from the pedal and be able to feel where the clutch is engaging thru the pedal rather then just feeling the delayed effects of engagement in the cars movement + rpm drop.

Thanks for the quick response Ryan. I also just sent an email which you can ignore.
So are you saying that vibration in the clutch pedal is normal? It gets stronger as the RPMs get higher.

Zthirty4NISMO 01-15-2017 05:13 PM
The pedal definitely produces a very noticeable amount of NVH. This is my only gripe on the product. I had thought the gearshift was bad at high rpms but this is more so at any point in the rev range.

Just went back out to test drive again and all i can say is wow! As everyone else has mentioned, it's the same as all other clutches and I'm very satisfied!
Definitely a great product and I'm glad I finally installed it.

Some people seem to notice more vibration then others which I can only attribute to some clutch setups having more harmonics/vibration at the pressure plate then others. When I install them locally doing before/after test drives it's typically not very noticeable but some increase is normal as the oem pedal was numbing down the whole clutch system feel with a stiff spring damper. These cars do have a lot of vibration thru the drivetrain in general and aren't exactly what I'd call smooth at higher rpm's so the vibration you're feeling isn't caused at all by the pedal or bad setup... You're just now feeling for the first time how much vibration is normally present in the clutch/transmission on these cars.

OK, I just got my car back with the new pedal assembly and it truly made a night and day difference. Launches are easy and smooth. First to second gear shifts are as smooth as butter. It really made the car so much more enjoyable to drive. Thank you Ryan for seeing a problem that needed attention and making a quality product that fills this need. :happydance:

Purchased one back in 2015 and absolutely love it. question to you RJM has their been updates or revisions since then? I wish I could lower my engagement point closer to the floor like I've been used to in other cars. Thanks for the great product

McLovin2010, yes there was a major update to Rev3 in winter of 2016 that saw many updates in both how the units are installed (much easier then Rev1/Rev2) and had new adjustment mechanisms keeping with the theme of seriously reducing install time. Thru all of that many who upgraded from Rev2 to Rev3 have told me they didn't initially believe I could have improved further over their older models but I had. With the Rev3 system you can get your engagement right on the floor no matter what clutch setup you're running. When paired with a Gen2 HD CMC it gives you even more setup flexibility as the Clutch rod on the Gen2 units gives you 4x the adjustment range of the oem master cylinders.
Hope that helps :)

Does that lessen the amount of disengagement on the clutch and cause it to drag/notchiness?

That sounds magnificent!!!! exactly what I've been wanting out of the clutch. props for continually advancing your already amazing clutch pedal. I will be in contact with you when im ready to switch out the v1. Do i have to do a whole new purchase or is there a way to just update the one i have? or do you do any discount for previous owners?

Nis350, it's completely adjustable for each individual's preference and clutch type. When properly adjusted the engagement can be lowered significantly towards the floor while still ensuring complete clutch disengagement. In fact part of the adjustment process is specifically testing to ensure full disengagement before finalizing the settings to ensure no drag or notchy shifting from engagement being too low.

McLovin2010, thanks for the props. As both designer & fabricator of these I'm always taking feedback from customers and striving to improve the adjustability while working to reduce the complexity of install/install time. While the Rev1/2/3 all look very similar the current Rev3 is a complete redesign and doesn't share a single component in common with the earlier units so a complete replacement would be needed. Shoot me an email when you're ready and I'd be happy to work something out as a returning customer.
Best Regards

Just completed an install of the RJM HD Clutch Master Cylinder (CMC) along with a re-install of the RJM Ver 3 Clutch Pedal Assembly. Great products ... and always great service from Ryan. He even provided instructions over his personal cell phone when travelling back from a visit to Niagara Falls with his family! Can't beat his products or his service. Thanks Ryan!

Dear Ryan @ RJM, just wanted to raise my high interest in a RHD version of your famed Rev3.3 AFP Clutch Pedal System.
You may remember, I am the guy who helped you with photos to develop a RHD version of your HD CMC Rev2, back then.

My current combo of RJM HD CMC Rev2, ZSpeed HD CSC, and CompetitionClutch Stage 2 Street 2100 gives me a terribly stiff and heavy pedal feel with very early and narrow engagement, often jerky/sticky predal travel. And stop-and-go is a PITA.
I hope your pedal assy can easy my problem.

Best wishes
René

Has anyone had an issue when installing this pedal where the clutch does not engage?

I just finished install of v3.3 and followed all the instructions (except the clevis end upgrade, i left the stock one on) and when i put the car into first gear and release the clutch it seemed to be engaging fine.

I went out for a quick test drive, however it may not have been fully engaging, as it was slipping soon after, about 0.5 miles into my drive the clutch is not engaging at all, i put car in 1st gear and fully release clutch and car won't roll.

I adjusted the upper brown switch to such a way that it would be pressed just slightly as the pedal was fully released.

is there any adjustment for clutch engagement i should be looking at?

You may have to adjust your master cylinder rod lenght. Basically the position at which your clevis end is held in place with the nut

Hi [mention]Ryan RJM [/mention] Just a follow up on the initial request from [mention]V1H [/mention], has there been any further development on a RHD version?

When we spoke about a year ago you were finishing up on a prototype for testing. Please let us know as we are very keen to get this product.

Thanks
