I'm wondering if anyone has had any experience with the centerforce clutch's. I know lots of people like act, but I'd like to know how centerforce does.

 

I have the DF clutch on my rx7 n/a and have had no problems with it.

 

same here, a DF on my NA for 4 years without problems...many people here hate centerforce - proper installation is really necessary, I broke mine in for about 200 miles before I started with hard shifts.

 

I would think proper installation is necessary for any clutch What do you mean?

sdrotary: How's the pedal pressure?

 

The pedal pressure is only a little bit stiffer than stock i drive 100 miles a day on it without complaint.

 

i drove a honda with a ceterforce dual friction (so i cant vouch for one on an rx7) but i recal it having tremendous clamping force with the same linearity as a stock clutch and only a little more effort. im probobly going to get one when my oem clutch finaly gives out. i'd think the dual friction would be best for someone with either lots of mods and power or plans on doing autocross/roadrace because it doubt it would slip enough for a good drag launch on a stock drivetrain.

 

I got the Dual Friction in my FC NA and I lot it. It grips damn good and as others have said not much more stiff than the stock one. Definatly a good choice for a performance clutch. Also i only paid $100 for mine new so I'm not complaining.

 

For some reason even experienced mechanics seem to have trouble installing the CFDF clutch correctly.

The CFDF pedal pressure on my TII was even lighter than stock. It was installed by the previous owner about 3 years ago, and the clutch still works to this day for the current owner of the car.

 

Sounds good, just like they advertise, more clamping force, less pedal pressure.

Why wouldn't it be good for drag launch, is it that difficult to slip? Is the dual friction bad choice for a daily driver?

 

My CFDF pedal pressure is the same as stock also. It does not have many miles on it but it will slip over 6k rpm in my turbo SE if I floor it. The next clutch will be an ACT one.

 

the car i spoke of i only drove for a little while. i didnt actualy do a drag-style launch but i recall the owner dumping the clutch in third gear after spining the engine up to redline, am\nd the cluch grabed solid, no sliping, and spun the tires. if it wouldnt even slip when in third gear i image it would probobly not slip very much in first gear unless worked properly. what im saying is that it probobly will not slip if it is fully engaged, but you can still make it slip by only partialy enggaging. so the technique of dumping the clutch and letting its lack of clamping power do the slipping for you will not work unless you have lots of power.

 

it will engage smoothly for daily driving but you might have to bump the revs a little

 

I've heard of people screwing with the centerforce weights before installation - they require no setup as they are moved by forces acted upon the clutch.

 

I have run 2.1 -2.2 60 foot with my DF centerforce, with Kuhmo 712's and just a few bolt's on on my 86 n/a.

 

so what's so difficult about installing it? Why would mechanics have a hard time installing it? I would be installing it myself, so if anyone has some pointers/installation tips, it would be very helpful.

 

Wow, this caught my eye!
NA guys keep complaining they can't get better than a 2.5 60', but your posts blows that away.
What's the 1/4-mile time and trap speed on your beast?

I just got a centerforce II for my S5 Non-turbo off of mazdatrix.com. It was cheaper there then on centerforces main web site!!! Haven't gotten it yet but can't wait to put it in!!!

 

if you mess with the weights before installation the release bearing, i think, will not seat in it right causing the clutch not to work right.

My pedal pressure increased on mine considering after I put in my DF the master and slave cylender blew up and the line also.

 

ya got that sucker in yet?

 

It would be a great clutch for street/strip driving. but it does slip with my 270hp turbo motor with an na tranny on it, but that is to be expected. Overall I have abused the **** outta my tranny and clutch. Both are showing wear, but still working well. I say that for an NA it would be great even for a street only car.

 

Why should the slippage be expected?

 

i would not reccommend a centerforce, act all the way.

had a new centerforce dual friction on my car (description in sig) and without shifting hard or donig anything to speed-up it's wear the clutch surface FELL APART in the transmission causing the transmission to always be engaged which left me in a difficult situation to get it home. nothing was installed wrong at all, the disk surface (3/4 of it) simply ripped and fell off the disk. so i swapped to an ACT S/S and one of my dumbass friends literally SMOKED the clutch maknig more smoke then a burnout and i can still launch the car perfectly at 4250rpms after that.

oh and i got the ACT clutch disk for like $125.

270hp on a n/a clutch? think about it

 

I had a CFDF clutch in my NA with mods below and eventually had to remove it because it was slipping. It only had about 10k miles on it too. On the other hand, my friend has one in his turbo wich is putting 300+ Hp at the wheels and its not slipping at all. Go figure...

 

i have a 1990 t2 with almost 325rwhp.
i use act. i have dropped/side stepped the clutch a 4500 rpm(1st gear standing start) with very little if any slip. i also had kuhmo ecstas on the car. pirellis suck!
