Even though making fiberglass gauge pods for rx7s paid for the engagement ring....
I'm down in Naples, fl
Congrats on getting married. I had a 90" rx7 convertible. Very Fun car. Never got the gauge pods so i can say i didn't contribute to the ring. But if you start this business one the side i will contribute to your Man Cave Fund
I knew I forgot something, photos. Here is one of the completed install. The clutch pedal now sits lower at resting position, closer to the height of the other pedals.
I have only driven the car around the block and to work, but ohh man! I am going to have to re-learn to drive my own car. The clutch pedal sits 5 inches off the floor now. I have about 1/2 to 1 inch of motion at the top before I can feel action on the clutch and there is about 1/2 inch of space at the bottom. Vastly superior to the previous settings. Just having the pedal sit lower (more a result of adjusting it) is nice. It is nice because the clutch begins to engage almost immediately after I bring the pedal up from the floor.
Also my clutch pedal was sticking before and does not now. I have already cleaned the heck out of the fluid. I think the better lever arm position will help the spring do it's job.
Thanks again.

so by doing this u have made the clutch pedel lower to the floor and have less movement to engage the clutch?
By doing this modification we have widened the safe adjustment range for the pedal, which allows you to lower the pedal further down. My clutch only requires about 2" of movement.

ok and does the clutch engage closer to the floor?
Update: Over 15k miles on the modified pedal and no issues to date.
OEM clutch engagement is beginning to get softer (60k miles on car) and anxious to get a lighter flywheel so:
Southbend Stage 2 Endurance clutch kit, Southbend DXD flywheel, Zspeed Heavy Duty CSC & Wilwood Master cylinder all on the way.
Another user of the Wilwood Master / HD CSC reported his clutch engagement window had been widened with this master cylinder. This leads me to believe it is a smaller diameter bore than the OEM master. I'll give it a full engineer investigation and report in a new thread.
I'm interested to see how this new master works with my pedal assembly.
I've racked 3k miles since the new clutch and must say its very good, I can put the pedal right where I want.
The z speed stage 2 "endurance" clutch works great with the pedal mod, giving me uber crisp shifting and zero shudder.
I drove a friends 60k mile stock g35 last week and I could barely drive it was so sloppy. Felt like a teenager learning a stick while hunting for the engagment point.
Z speed master cylinder did not seem to widen the engagment, was changed with clutch, flywheel, and HD CSC so too many variables. I can say the combo is much tighter and crisper than stock. No regrets at all.

I got the daily Stage 2,love it.I noticed my first gear to second gear shift got smoother with the upgraded CSC and Willwood master.My clutch is still high like factory but it shift way better than factory.
Im still not understanding this fully. sorry :/
My engagement point is at the very end (got a new clutch a month ago)
So when the clutch is fully engaged and let off. I have less than an inch of play room
And is mod will....?
in dumbed down words
(put my engagement point lower and still having that stiff spring and more play room afterward??????)
I know this is a really old thread, but I bought my z in 2021 and this thread was one of the few that actually helped me diy my own clutch peddle. After cutting off the tab as described in previous post, I moved it in the opposite direction and replaced the factory spring setup with a normal tension spring. The spring cost me $1.50 at my local ace hardware and now I have a normal clutch peddle with out the wierd switch effect the original setup had.
Unfortunately the spring didn't come with any specifications, but there are a bunch of 2-inch long tension springs on Amazon that you could test to adjust the clutch feel to whatever you prefer.
