I installed a Carbonetics clutch after my Exide coun't keep up with 15 psi of boost any longer. In the beginning it engaged very fast, had to push the pedal to the floor and it would engage close to immediately. It needed bedding in, nowadays it engages like a stock one would. Took a couple of days of driving (normal driving, no burn-outs or whatever).

Rock solid clutch! Even driving in slow traffic and stop-start-stop driving in traffic jams is close to normal.

I dont know what "two" adjustments you refer to. I know only the one where you can spin the rod. That changes the engagement point and it changes the freeplay at the top.

Very interesting. I had no idea the height of the pedal can be regulated with the clutch switch.

clutch
 
i use the flying miata act 6 puck clutch on my 94 diy turbo :jerkit:

. High clamp force, lower friction with the SS(organic street disc) in the ZM2-XTSS is rated at 307 ft-lbs.

I have this clutch set up and all my cheap turbo miata friends hate me for it because its so easy to drive and it last and last with alot of abuse. i have had it for more than 45k with out a single problem. i have drag raced it well over 200 times and i have abused the hell out of it and it still feels new. it is real easy to drive in traffic and even my sister was able to drive it and she weighs 105 pounds. the pedal is a bit stiffer but after you drive for a week its like butter its feels normal and smooth. i guess your left leg just gets that much stronger. i cant drive a stock miata clutch it feels so weak to me now. the only down side is the price from $460 to $530 but i would pay the high price one time compared to my freinds that end up buying a cheap one every 15K-25K miles. but ACT is the best and all my friends now will save a bit more money to get ACT. my clutch is still good i wonder how much longer it will last.

I'll throw an update in here. I have 250 miles on my ZM1-XTMM. I love it. The clutch pedal has become much softer and the engagement point has moved up a little bit. Don't be afraid of the xtreme kit, it really isn't bad after it breaks in.

On a side note my trans really needed a flush. Buttery smooth shifting now. Feels weird to roll up to a light and 1st just drops into place.

Ha, mine goes in first with no effort if I'm rolling less than 20. Good transmission.

That is how mine is now. I keep thinking something is wrong.

This is a must. Good info.

Friend of mine had a motor swapped integra. He ran a step up from stock clutch and it started slipping. Well he was pissed his new clutch slipped so he ordered and installed the puck clutch. Well it didn't slip. Problem was it was an on/off switch. Car lost a lot of the driveability and smoothness it had before. Maybe that doesn't matter to you, and over time you'll adapt and somewhat overcome this, but in all seriousness it sucked. You have to be good at rev matching when shifting or you would shake the car and put a hard load on the drivetrain. Plus shifting it fast when driving hard is PURE HELL on everything behind that poor clutch. His stock transmission lasted for 4 weeks. Then one day shifted into 2nd and the transmission exploded.

The clutch in the drivetrain is like a fuse in an electrical system. Bigger is not always better. Now I'll admit I HATE a slipping clutch. But then again I'd rather it slip for half a second when I grab second gear in the 1/8 mile driving 10/10ths then it grab so damn hard that torque loading breaks shit that's behind the clutch. You can be more gentle with a strong PP and stock disk vs a puck setup.

I had a friend with that EXACT absolutely the same situation...drove that thing..HOLY HELL!!!! Id rather drive an auto than his integra, it was the worst fucking clutch ive ever felt

Was it a solid puck or a sprung puck?

Braineack 09-16-2008 04:44 PM

I drove a miata with an ACT HD 4-puck unsprung disc this weekend. Was easier than my ACT HD with a clutchnet 6-puck sprung disc. I assume it's the friction material as I have a clutchnet disc, however the same PP.

I went back in and readjusted my engagement rod length, it's at a typical height now, still grabs but it's a lot easier to deal with.

Honestly, my dad drives this car a lot. If he can do it without issues or complaining, anyone can.

Braineack,

How did your F1 clutch perform? Did you run one of their flywheels too?

Braineack 09-23-2008 01:05 PM

what makes you think I'd ever ran a F1 clutch?

the F1 Clutch is an oem rated PP with the same exact disc I'm using. I've driven a miata with one, felt just like any 6-puck, with a soft pedal.

Fritz 09-23-2008 01:19 PM

I interpreted your post about driving an F1 clutch as having one.

Interested in impressions of F1 stuff.

May try their flywheel but havent used or seen any of their stuff.

Saml01 09-23-2008 10:35 PM

So what was the final outcome of the Clutchnet stuff? Poor tolerances in their product caused problems or are some people successfully running them?

Braineack 09-24-2008 09:50 AM

It's random. Some people had zero issues, others didn't have that luck.

it seems the PP design is to blame, I'm still using the disc I bought with an ACT PP.
