Review: RJM AFP Clutch Pedal System

Kamillio

I've installed mine now. It's even more tricky to drive this one than the stock! I don't know what I did wrong but my engagement point is really close to the floor but the clutch pedal rests almost even with the brake pedal with stock adjustments as recommended in the instructions.

I don't know how to improve my driving experience.

Kamillio, glad to hear you got it installed today. I'll walk you thru getting it dialed in better as your description is certainly not how it should feel when setup according to the guide's initial recommendations.

First off getting the friction point too low is absolutely just as difficult to drive as too high since you have no room to modulate before it starts grabbing.
The minimum recommended initial friction point as tested on level pavement is 1.5" up from the floor. Any less makes it's difficult to drive and there is a possibility for not fully disengaging the clutch. Now when you say you currently have the pedal almost even with the brake I'm guessing you mean the pedal is too low and not up level. It should be either level with or up to 1/2" above the brake when setup per the guide.

To bring the initial friction point up to where it's more comfortable you'll need to loosen the lock nut behind the clevis and thread the clutch rod counter clockwise to raise the pedal and in turn the initial bite point.

In addition to this you may want to recheck you have the AFP setup correctly to between 70-80%. To do this you can loosen the AFP lock bolt and turn the red knob clockwise until the sliding plates are fully retracted. This is the 0% point. Now keep careful count as you turn the knob counter clockwise 7-8 full turns for 70- 80% AFP. Mark the knob with a sharpie marker to make counting full turns easier if your knob doesn't have a mark already.
Once the AFP is set you can push the pedal arm down about half way to remove all slack from the pin while you tighten the AFP lock bolt.

Once you've ensured the AFP is set correctly and raised the friction point up a little it should feel much better then stock.

Let me know how it goes.

Thanks,
Ryan@RJM
