F1 stage 3 racing clutch, weak PP?
I know not to use the F1 racing clutches because people say they have weak PP's and don't last long because of it. But my Mazdaspeed stage 3 racing clutch was supposed to hold but now its slipping after 4k miles on it. So I can get a F1 stage 3 racing clutch and lightweight flywheel for about 350. I hear the F1 clutch disks work fine and my friend is still using a F1 setup on his turbo supra and its still holding at 15K so thats a good indication of a good working clutch disk.
So if the F1 clutch disks are good but the PP's are soft would it work to use my almost new mazdaspeed stage 3 pressure plate with the F1 clutch disk and flywheel?
This isn't a XTD crap clutch kit like the ones for sale. For some reason no one has info on the F1's but does have info on how soft the XTD's are.
This car doesn't get driven a whole lot but does put out quite a lot of power so I need a stage 3 and I got off the phone with F1 clutch and they "guarantee their stage 3 clutch to 400hp". Any thoughts on these clutches? hopefully some good news.?

They work for a stock replacement, but anything designed to "hold power" sucks ***, I know, I've tried them.
Why is your mazdaspeed clutch is slipping? If its rated for the power then it should be fine unless something wasn't installed properly......was the flywheel resurfaced correctly?

ya, had the flywheel 3 stepped resurfaced and everything. The mazdaspeed clutch (3 puck triangle looking) clutch worked great and bit hard for 4 thousand miles and just within these last 2 weeks its started to slip worse and worse. Eventually the peddle got lighter than stock and driving it was a challenge and I just took it back out to see what happened. Nothing is wrong with it and it was installed correctly and everything. Maybe the pucks are just too thin or something. The mazdaspeed stage 3 should hold 400+ but it wouldn't hold half that. I even broke it in along with the engine and as soon as I started giving the engine boost it started wearing out.
won't hold power? They claim 414 or something this one will hold and gaurantee it all if it doesn't. They even faxed me the warantee info and wouldn't mind sending me a signed statement honoring their warantee for it.
But this is why I'm asking. even though I don't drive this car hardly I would like a clutch that doesn't slip when I do drive it OR slip when I'm powering through a turn and send me into a unintentional drift when I suddenly get power to the wheels again when I let off the gas. Let me tell you about that, it scared the hell out of me. And that was the last time I drove with that clutch

sounds like a posible hydraulic problem. If it isn't dissengaging the whole way, check the pedal rod adjuster. Make sure there is no preload on the master cylinder. If all checks out there, It will be something like a bad master cylinder or slave cylinder.
I personally run an act hd pressure plate with a STOCK (yeah, thats right) disk. I haven't had any issues at all with this set up, and my car dyno'd at almost 260whp.
I feel there is something else wrong with your setup. Don't use crappy clutches, you'll just regret spending the money at all.

Well I honestly think somethings up, I know the Mazdaspeed stuff is of *MUCH* higher quality then that F1 grip force crap.
Was the MS PP new?
Did they resurface the PP mounting area along with the flywheel surface?
How scored is the flywheel and PP after having the 3 puck slip?
Its even more odd that a 3 puck would slip. I've only had one 3 puck friction plate installed in my car and that was on a stock turbo at 12psi using the OEM pressure plate and I would honestly wager that thign to hold ~350whp with the stock PP....a clutch like that is just ssooooo aggressive.
If you're confident in their garuntee and don't mind pulling it out when it fails, by all means go ahead But I'm tellign you from personal experience that the F1 stuff is no good above stock power levels despite what they tell you and advertise - I tried it. Ran the 6 puck with the "stage 3" PP, pedal was as soft as stock and it would slip in 2nd gear past 3500rpm everytime, so in the garbage it went with less then a week's use.

True. I paid 600+ for the damn mazdaspeed clutch, brand new too. as for the slave and master cylinder Idea... I took the slave cylinder off the trans and set it aside and push started the car and grany shifted to 4th and gave it some gas and sure enough it slipped. So I know its a clutch problem. this car is around the 300 when it can boost up with out slipping but right now the clutch couldn't hold a VW bug engine power. technically the mazdaspeed stage 3 shouldn't ever slip unless you throw it on a turbo 20b or something outrageous like that.
But like I said the flywheel got re surfaced and the clutch didn't need to be re surfaced because it was new.
Taking the trans is no more than a 20 minute job at my shop so yeah I don't mind. Maybe I could take the F1 friction plate and use my mazdaspeed PP and then it would be a better setup? Oh and the F1 clutch kit would come with a new lightweight flywheel which this car doesn't have so I am getting one good thing out of the deal

Well some good news guys. I broke down and dumped a good amount of money into this RX. How's this for a clutch setup?:
Exedy racing clutch disk
Exedy racing Pressure plate.
both mounted on a
Fidanza lightweight flywheel
I think this should hold for a long time
