Thinking about upgrading my clutch .. I have a 4 puck and I think I ate threw it already so considering this option. Is anyone currently running this in their FC? I don't mind having a stiff/hard clutch, I rather enjoy it lol.

ACT Z65-XTR6 Clutch Kit

Xtreme Pressure Plate
Clamps load increase of 50% to 120%, Pedal feels moderate to stiff, Many SFI Certified to insure safety
R6


Solid Hub (6 Pad) Disc
Increased torque capacity, Faster shifts, reduced inertia, Very good durability but shortened spline life, Absorbs more heat than 4 pad, Harsh engagement, some chatter

 

the clutch disc is good but i would go with the heavy duty pressure plate if i were you

 

Im runnin a sprung 6, pedals not hard, no slip at all, just break it in right.

 

I have the unsprung with the heavy duty pressure plate... and a lightened flywheel.

One of my favorite purchases. All these crybabies that whine about the unsprung are a bunch of pussies.

 

Stay away from the Xtreme pressure plate!!! Lots of people have broken clutch hydraulics/pivot ball/whatever with it. our clutch system just doesn't like it

 

Broke one of those in a 240. I'm running a sprung six puck cause I don't like how the solid disc just kicks your *** in a daily driver. Also running an xtreme pp and I haven't really had problems except for the bent master cylinder push rod and the cracked in half clutch fork but those were there when I bought the car. The set up definitely grabs hard. It makes the tires chirp going into 4th some days. But I do happen to have a solid disc for sale for a TII if you are interested. It was bolted into an engine but the kid didn't know a thing about RX-7s so it was never ran. Let me know if you are interested in it.

 

The extreme PP is too much for the street. You are not making enough power to warrant it and your leg will HATE you for it. I have had FD's around 500rwhp on a SS clutch. Seriously, pedal stiffness with the XT plate is insane. And yes, it is very hard on everything else...the pedal/bracket, the master and slave, the soft line, the fork and pivot ball, and throwout bearing. IT is so hard that it actually causes the throwout bearing to eat into the PP fingers over time.

The 6 puck discs arent to my liking if they are solid hub. They are unforgiving, and they make even an experienced manual driver look like a jackass around town. These cars are hard enough to get moving with the lack of torque and such, and this just makes it worse.

If you can find a sprung hub 6 puck then that would be ideal.

The ACT HD plate is all you need.

 

i got the heavy duty pp my baby dont like all that xtreme stuff it'll break her, its bad enough im not spung, shes hard to handle if your not use to her ya know

 

How much power you making/planning on making?

The HD pressure plate and street disc is good for 330ft/lbs of torque which on an FC block is nearly 450whp.

That clutch is in my car now and drives damn near like stock. Wouldn't trade it for the world.

 

i plan on ultimately making around 350-375hp and abuot 290-320 torque

 

you'd be lucky or nearly the first to break 300ft/lbs before 400hp on a 13BT.

Either way, the HD and street disc are still up your alley. If you've ever driven a puck clutch before on the street, you'll know why I'm leaning away from it.

It can be driven well, it can be driven without stalling/jumping etc. but in order to do so a few things will happen. One is you will D-E-S-T-R-O-Y your flywheel because you need to slightly slip the clutch to take off smoothly from say a hill at a light, in traffic, whatnot where you aren't jumping right on it.
Second is backing up. This becomes extremely tough to modulate with a puck clutch and helps turn your flywheel into garbage also.

Now, don't get me wrong, I drove a 6 puck for nearly two years before. Can it be done? Sure. Could I drive it through town/drivethroughs/wherever? Yes and I did. Is it VASTLY easier on both the car, my leg, my passengers, my flywheel and the traffic around me without a puck clutch? Damn straight. Does my clutch setup hold my power level? Damn striaght.

I can't make up your mind for you.

 

There are people here saying "ah, if you don't like this stiff clutch you are a *****". Well, it's not that. We all like these cars and we want to enjoy driving them. Putting in an extreme clutch setup (or making any modification that substantially detracts from driveability) will make the car much less fun to drive...it'll turn into a chore. That's the point I'm trying to make here.

I've built lots of cars and installed lots of various modifications on customer cars, and so I have a unique standpoint on what works well. Invariably the "hardasses" that say they want such a stiff clutch tell me a couple of months down the road that they regret going that route and wish they had went with something more conventional.

Just because a part is called "race" does not mean it will make your car any faster on the street, nor does it mean it's the best of all the parts available. To me, that usually means "too much compromise in driveability to use on the street".

 

daily drove (and drag raced on a strip) my nonturbo with a 4 puck unsprung for over a year. It pretty much destroyed my drivetrain. I blew my diff, engine & tranny mounts, and my transmission completely **** out on me. Of course this is an n/a drivetrain which is weaker than a T2.

The problem is that there is no point in a puck clutch unless you really are driving the car hard. Yet if you have enough power/abusive launches to make use of the clutch you are going to break **** all the time.
