Would you recommend the puck or organic for a 02 NB with the 10lb flywheel that is street and track driven (track 2-3 times a month)? I'll likely be going boosted in the next 6 months... I currently have a relatively new Exedy KMZ03 with the 10lb flywheel (3000ish miles) and it already started slipping at the track this weekend.
Thanks!
How much torque? Match the clutch assembly to the torque output of the engine with the information published on our website.
The sprung puck can be driven on the street quite easily. A bit more abrupt engagement than the organic but not terribly so.

This was exactly why I ordered the sprung puck. I want it to be able to handle what I plan to do with it in the future, and I'm not opposed to giving up a little in the smoothness of engagement in order for it to handle what I plan to dish out to it. So yeah, did a lot of reading and comparing before I came to that decision.
Just weighing in on my Supermiata clutch and flywheel, I went with the lightweight 1.6 Organic/hybrid clutch and 8lb aluminum flywheel. It's really responsive and revs so freely, which can also make it tricky for others driving the car around the street for their first time. I also notice the clutch much prefers to be rev matched (duh) on down shifts or a small little blip of the throttle when letting the clutch out wihen slowly moving down a gear on the street, otherwise I'll get a little shudder through the drivetrain. Otherwise clutch pedal is near OEM light.
Car is 1990 with VVT motor and Rotrex making 243hp/193tq. So I'm nearing the torque recommendations for the 1.6 clutch but I've not noticed any slippage or issues, even with autox. Would purchase again!
Just making sure, the torque rating on the website is for wheel torque not flywheel, or am I mistaken?
I drive a 350z and the number one thing I hate is the abrupt engagement of the clutch. I bought a 90 miata as a project car and the torque limit of the 1.8 organic is what I'll build the engine and cooling around. Cause you know. Streetability.
Finished installing the clutch/flywheel package this weekend. Still have a few things to take care of before I'm finished with the 6 speed swap. Trans is in though, just need to give everything a good once over, and put the bottom of the chassis back together. Took a few photos of it while putting it all together, will post them up later. Got to get cleaned up and eat something. Will finish next weekend.
Went for my first drive this weekend, and the clutch, flywheel, and transmission all feel exactly the way I expected they would. I don't think I could have chosen a better package. Clutch engagement happens at the low end of the pedal and compared to stock, is slightly abrupt, but not irritatingly so. Clutch effort doesn't feel a whole lot different from stock, but modulation is more difficult, although I expect this also has a lot to do with the lightened flywheel. For someone used to driving a manual all the time, its manageable, but to my wife, who has driven automatics now for most of her adult life, its a lot more challenging but not impossible, she just had to work at it more. Definitely not what you want to teach your teenager how to drive in. Since I am still breaking it in I can't comment on the acceleration of my 6 speed with the 4.30 in it, but I do intend to start another thread on that later. For right here I'm staying on topic. This clutch had a proper install, using proper torque values, and a sanitary installation free of contaminants. After proper break in, I fully intend to let it have it to see how much my acceleration has improved with the whole combination.
And the best news is that I'm going to need a brake job soon. SuperMiata can plan on hearing from me about their Wilwood brake package soon because after this, they will have my business in the future. Never met you Emilio, but thanks man.
If you used the sprung pucked clutch, it doesnt need break in.
Yeah, I did get the sprung puck, but I’ve never hammered on a new clutch in my 35 years of wrenching so it’s no big deal to break it in for a few hundred miles. Not saying you are wrong, just that I might have an overactive mechanical sympathy gland that disconnects my foot and brain in order to prevent abuse too soon.
Is it normal for the clutch to engage at the very, very top of pedal travel? I've tried bleeding it a ton of times and adjusting the clutch pedal but nothing changes. Adjusting it lower makes the car not want to get into gear.
1.8VVT motor with 1.6 organic full face with sprung hub and 1.6 8lb flywheel. I feel like I'm going to burn up the clutch driving it like this and it's impossible to drive smooth anyway.

With a heat treated diaphragm spring like we use, yes that is as it should be. Roughly same engagement pint as an OEM clutch. It's unusual that someone would not be happy with that. Cheaper clutches just use thicker, non-heat treated diaphragm springs that give a heavier pedal for the same clamping force and engage near the floor. Those are not good things.
You can adjust the pushrod going into the master and also the freeplay on the cruise control switch. Make sure you leave a few mm of free play on the pushrod at the top of the stroke or you will kill the clutch.
Bleeding will only make it engage higher if it had air in it, not the other way around. You have a very light weight, high performance clutch assembly. It will require a bit of finesse / learning curve to be fluid with it.

As far as I know I had a full OEM setup in the car before. It would engage around the middle of pedal travel, maybe slightly higher. The Supermiata clutch is engaging right at the very, very top of pedal travel. Like very last mm before your foot is completely off. Just want to make sure there's not something wrong will the tool turning wrenches is all!
Edit: Reversed what I understood the FM Clutch adjustment procedure should be and the clutch engages much closer to the middle! Looks like it was a problem with the tool turning wrenches after all.
My currently clutch(OEM clutch and flywheel) started to slip at Laguna Seca this past weekend, time for new clutch! I'm looking at one of the sport clutches(organic sprung) as well as a lightweight flywheel. The car is track focused(3-5 events a year) with the occasional weekend drive every few weeks. Engine will stay N/A with no current plans for boost. Car also has A/C and power steering with no plans on removing them.
How much of a difference am I going to notice between the 1.6 and the 1.8 lightweight flywheel setups? I know that it's going to be fun getting used to driving with a lightweight flywheel. I'm curious as to how much more difficult it'll be to start the car from a dead stop between the lighter 8lb 1.6 vs the 10lb 1.8 flywheel. Will I also see a noticeable difference in response and engine revs between the two? I don't care about any extra noise and vibration, I'm more worried about driveability on the street as well as performance.
