Default Review: RJM AFP Clutch Pedal System

Just installed my new RJM clutch pedal and I wanted to do a review.

DISCLAIMER: I have no affiliation or connection with the company other than nagging them to to make the product for the 370z/G37.

Ever since I found out about this clutch pedal system on the 350z/g35 forum, I got into contact with Ryan at RJM Performance and asked him to make one for us. After 6 months of development, I finally received the prototype for testing. I paid for the pedal, so i dont want anyone thinking that I'm obligated to give a positive review.


So the problem with the stock clutch is the high and narrow engagement point. The high engagement can be alleviated by adjusting the clutch rod, however, the engagement window cannot be changed. This the where the RJM pedal shines. Using an easily accessible turn knob, you can change the pivot point of the pedal. This basically in turn causes the engagement window to increase or decrease.


Installation is fairly straight forward. I'll let the pictures do most of the talking.


After the installation, adjustments to the clutch pedal feel can be adjusted with the turn knob. The best part about this pedal is being able to make adjustments while driving. You can fine tune the pedal feel as youre driving. Once you find the sweet spot, then you can lock down the setting.

Turning to the left raises the pedal and increases the engagement window. It also softens the pedal pressure. Turning to the right lowers the pedal and shortens the engagement window. Using this AFP knob, you can basically change any clutch to soft and smooth cruising mode or stiff and grabby racing mode.

As you can tell from my signature, I have the OS Giken multiplate clutch system. They are notorious for difficult to drive on the street. There is no engagement window, it is either ON or Off. After installing the new pedal, there is a night and day difference. I use to have to start at 1800 rpm from a stop to avoid stalling. Now I can start in first gear with no gas applied. The engagement window is longer and I can modulate the pedal to make every gear shift smooth. The 1st and 2nd gear used to be jerky but is completely smooth now.

I highly recommend this pedal to every 6mt driver. If you have an aftermarket clutch, this is a must. If you have trouble driving with a stock clutch, this will improve your shifts.

So let me make sure I understand this, even with a stock clutch, shifts will be smoother and easier? And what are the downsides of having a wide engagement window in terms of aggressive driving?
I like how you can adjust it on the fly. Might just have to pick this one up!

very interesting indeed! im only worried that changing the window might put more stress on the clutch or clutch components, no?

Thank you for posting the pics and reviews.

This is something that I will absolutely be purchasing sometime soon for my next set of additions to the vehicle.

I have the OSGiken twin and the ZSpeed CSC. While I have been happy with the durability (roughly 15,000 miles now) of the CSC and the holding power of the clutch... driving it is a complete nightmare. My friends think I am making up excuses to not let them drive my car when I tell them it is a NIGHTMARE and that it took me thousands of miles to get used to it enough to be able to drive the car smoothly and without stalling... and thats from being someone who has worked in this industry for over 10 years and driven countless difficult to drive clutches.

I have often wondered if its just the clutch that is so on/off or if the Zspeed CSC changes the pedal ratio, or perhaps a little of both... but its a serious pain in the ***!

This adjustable pedal looks like exactly what I will need to make my Z more driveable for anyone, and probably even save some wear and tear on my drivetrain and mounts/bushings just by having superior control over my clutch.

Man I know what you mean. People want to drive my car and they just can't do it lol. I get in my dads Vette with a 800 torque twin disk and it's easy as pie. I fine the system is really sensitive to temperature too. I hope this does it. I still stall it every now and then. Its like it don't move don't move them bam it's like it sucks my foot in lol.

Cosidering that some parts such as a small carbon fibre mirror cover can be sold for $400 a set this part is rediculously low cost based on the amount of parts and manufacturing that went into this thing.

Its around $250 plus shipping but better to go to their website and confirm.

Ordered mine last week for $220 Canadian which comes to $221.49 US. They were selling the first ones at a discount which included FREE shipping. Don't know if there are any still available at this price, so I would check their website. After trying to win one at ZdayZ (NOT), I decided to pull the plug and order one for my 40th. Now, all I have to do is install it. While I was satisfied with the clutch helper spring mod, it didn't give me the feel and pedal stroke that I am still looking for. I am 100% sure that this RJM AFP will do the trick.

Once installed, I'll post my opinion.

Yes Canada Post blows! Way more expensive and less efficient then the USPS. I live about 1.5 hrs from RJM so I received my kit pretty quickly. I beleve the initial offering of 220 shipped was a good deal for customers since it probably cost RJM about $50.00 to ship these kits to the US.

My kit was delivered to Cleveland in less than a week! Of course, we are only five hours away from Toronto.

Can't wait to do the install.
