what clutch are you using and why?
im in the market for a new clutch (while im changing the driveshaft, i might as well ditch the stock clutch too)
i have always used Exedy with great results, but i might want to try something new on the FC.
my car will probably never break 300whp, so lets say i am looking for a clutch to handle up to 300whp.
please vote for the brand of clutch you use, and then post what model it is, and how you feel about the clutch, and how you feel about the brand.
for example: Exedy stage 1, Exedy stage 2, Exedy hyper single..etc..etc..
thanks.

bullshit, it drives waaaaaay better without them it shook like there was a couple lbs of rotating mass out of balance. My weights or the weight ring they ride on were off/defective, normally its dead center even but my weight ring would move around the pressure plate irregularly.

Most people on this forum, and even many wanna-be performance shops, do not have the technical competence to install a Centerforce Dual Friction clutch properly, as seen by the above post. Therefore, it's not such a great idea if it is not installed by a competent mechanic. I absolutely loved my CFDF, but it was installed by somebody who knew what he was doing.
Exedy supports rotary events and works with the rotary community to enhance their products, so everything else being equal, you may want to consider Exedy.
Clutches are rated by torque, not horsepower. If the torque rating is not listed on the manufacturer's website or in their catalog, you can contact them for this information. Keep in mind that the pressure plate also affects the torque holding capability, which is why you often see matched combos for sale.
Clutches in my cars:
Stock 88 Convertible - OEM clutch
Raced-out 88 Coupe - QuarterMaster 2-disk 5.5" racing clutch
Former lightly-modded street 88 T2 - CFDF
Former 84 IT race car - ACT street disk

You can't blame that on the clutch though. Well, except maybe from the same aspect that I view it, in that the product has a disadvantage if it requires much more skill to install than the other single-disk clutches on the market. However, this is not a factor if the buyer plans on having a good performance shop perform the labor regardless of the clutch selected.

I have the df clutch in my 7 drove it today to 8000 rpm not a vibration at all plus i have a 73 firebird with the same clutch on a 12.5/1 compression bb making over 700 flbs i launch it at 3800 and it holds great.You can have the best part in the world and some dumbass will break it or install it wrong and then bash it. Remember tools dont make the mechanic the mechanic makes the tools

I only installed it because the stock clutch died and my buddy just happened to have it laying around his garage for his rx7, but ended up using another he got. it grabs good and is not heavy at all.

Yes, the CFDF has a very light feel. This isn't a problem unless you like to build up the muscles in your left leg, or you are trying to keep your girlfriend from driving your car.

Question: I have a CFDF in my n/a Vert and love the feel and grip. I bought the clutch used/low miles. There were very obvious marks indicating that the weights had been run off center. I emailed CF tech support and here is what they said.
Hello,
The weight will self centered providing all the dowel pins are being used and the balance of the pressure plate and flywheel meet the manufactures specifications. I would mostly be concerned if the weights were contacting the outside diameter of the throwout as thus could cause erratic engagement/dis-engagement problems. If you used his old flywheel and the pressure plate was rotated/bolted if possible, the weights could be running in a different position or if you bolted the clutch to a different flywheel it could change the position the weights are running being the flywheel balance between them could vary. If the clutch is operating properly without any shifting problem, I do not see a major concern remove it. Feel free to email me if you have further questions.
Regards,
Roger

The last thing I did before installing the transmission was to recheck the centering of the fingers.
Every once in a while, I imagine that I feel a vibration. My car is very smooth, and the vibration is something new, with the clutch. ( I did mark the driveshaft and the rear yolk to reinstall the same orientation). I kick the clutch and it goes away. I think the engagement is re-centering the weights.
Did I do this install correctly or did I miss something? What is the extra skill or detail that is needed to install these clutches correctly?
I appreciate your help.

and like I said I do not recommend them for rotaries but I had one of them on my 240sx (piston engine) that I installed and it worked fine and I know the owner I sold it to and its still fine and is holding more power than I ever had in it.
I'm just sharing you with my personal experiences and its like your all calling me a liar because [sarcasm] the centrifugal weights could never go bad. [sarcasm]
granted the guy I bought it from could have fucked it up but I'm not taking that chance again, I'm just going to buy a different clutch.

I would bet that a CFDF would be fine on a clutch designed to handle 450+ ft/lbs because the weights allow you to have a normal clutch feel with high torque holding. But for a stock n/a application, the CFDF sucks.
I know that its my opinion, but its my opinion. I don't know what you mean by building muscles in my left leg. I have pushed in a whole lot more clutch then the OEM clutch and never had a problem.

Running an ACT modified street disc (full face) with a heavy duty pressure plate.
Drives like stock, clutch pedal is *slightly* heavier, and has held over 330ft/lbsTQ at the rea wheels to date.
Almost 30,000kms on that clutch and flywheel and its still rocking out.
