Prices seems reasonable and the OEM clutch master cylinder is on sale. The reputation of Zspeed on this forum, their service, and quality of parts is definitely worth the price.

I'm ordering an axle back exhaust too, because why not. I don't plan on modding my car much as it is my DD, but I'm hoping these mods will make it better than it already it is. I already called a reputable shop near me and they will be ready. This is definitely adding up to be a lot, especially since I was not expecting any of this, but I'm looking forward to it!

Thanks to all of you who helped me.

I just went through almost the exact same ordeal when my CSC went out unexpectedly, and yeah, it's a monetary doozie if you haven't planned for it. Not including the CMAK I was lucky enough to already have waiting in my parts pile, an EXEDY Stage I clutch kit with a steel flywheel, gear oil, towing and installation labor from a reputable shop came to like $2200 I think. For what it's worth, the owner of the Z-Tech (specializes in Z/G cars, and has been here for like 20 years) said the CMAK was his solution of choice and was only going by his own experience. I was quite relieved to hear that.

I expect that you're going to be as happy with the change as I was, and feel like the investment was 100% worth it when you drive the car again. Like the kit in your link, my EXEDY kit also has a 20 lb. flywheel, and the car's response is vastly improved revving it up for a down shift or just taking off from a stop. There was no loss in street driveability (is that a word?), and it now feels like a sports car and not my dad's old Wrangler while running through the gears.

Joe's clutch movement alteration kit and upgraded clutch will definitely eliminate the pedal pressure and sticking to the floor issue. But the rjm pedal makes the pedal itself feel way better and eliminated the on off feeling of the stock pedal making shifts, especially 1 to 2, buttery smooth. It's a requirement in my opinion and completes the system.

I gotta agree with Joe on this one after my personal experience. With the CMAK and a properly matched single-disc clutch and flywheel, I no longer have the RJM pedal on my radar. It was just that much of an improvement.

I can put it this way: after driving the new setup for about 3 weeks, other mods will get prioritized in the budgeting department. However, since the pedal isn't too pricey and appears to be an easy DIY, I'd still give it a shot to refine things just a little more.

They're a mechanic shop in Central FL that does a ton of RWD Nissan work.

I personally chose them because they were flexible with letting me choose and order the parts I wanted installed.

I'm glad to hear this! Thanks for the affirmation. I'm eager to drive my Z again ASAP, especially with the new exhaust. $2,200.00 is about what I'm looking at as well after parts and labor. I'll circle back around with my review and hopefully some pics. As for the RJM pedal, I'm sure it's very nice and I haven't put it past me, but I just don't feel like shelling out another $400 when I personally don't think I need it to fix the issue at hand.

Thanks!
