I had an RJM Performance pedal on my 6MT and I want to encourage anyone with a manual G or Z to get one. https://rjmperformance.com/370z-g37/
It's an involved install for someone who's just a weekend wrencher like myself but the included instructions are detailed enough to make it doable. The available adjustment and customization are awesome and you can set the clutch engagement just the way you like it. Plus the pedal feel is way better than OEM. I did have ZSpeed's CMAK and sport clutch/pressure plate installed as well so I was going for a good OEM feel with a smoother engagement, and the pedal was the icing on the cake.

 

Another bump for RJM, I’ve had the Rev3.3 pedal I installed myself over 3? years ago now and have never had an issue. It was a game changer with a stage 3 daily clutch and 19lb billet flywheel. I also have the Zspeed CMAK kit that was installed by a shop with the clutch and flywheel.

If anyone is considering both the pedal and an HD CMC assembly, get them both and install at the same time. I grabbed the Tilton HD CMC from RJM years after the pedal but have yet to install it, since the pedal assembly has to come out again for that.
