My friend just installed an F1 clutch with this PP and it wouldn't disengage. Paid labor a second time to have a "real" clutch put in. What is it with these PPs that some dont work properly?

Could you post pics of the FAILED PP? Is there any signs of what or why it failed? Could it have been caught before install?

That is exactly why I will not use a cheap clutcch. I only want to do the job once and paying extra for an ACT or FM to gurantee I won't have have to do it twice.

I could post a pic of my PP over the weekend. It has to be a dimensional thing, the PP looks fine from a physical standpoint. IE, there are no broken fingers or anything.

The guy from Gripforce was a real douche about it when I called him, too. He basically told me that there was no way I would get my money back for it, even if I sent it back, so I didn't bother wasting my money sending it back. I'm sure I would have gotten better after the sale service from Emilio, but I double cheaped out on it: 1. by getting the F1 parts and 2. by not at least getting them from 949. I'll be doing ACT for the time being, I've now had three and they have been perfect.

I have the F1 with an exedy sport PP and clutch an I loved it.
Saddly it lasted only 2000 miles. Not that the clutch assembly failed, but I failed to put some sticky stuff on the flywheel bolts to keep the oil in the cranck..
And now oil is getting out on my expensive upgrade...
I haven't decided to pull either the engine or the gearbox.. But even soacked with oil: no slip. I did not push it though.. Right after discovering the spill I have put the car asleep for the winter. When I have time I'll fix it. Can I just clean up the clutch and re-use it? As it have done no more then 2000 miles and I did not drove it to destruction. But I don't know if I'll get all oil out of the clutch.

Any advice?

I've got the fm flywheel with an exedy stage 1. I figured the chinese can machine something flat, but mechanical I'll leave to the japanese. So far so good. The thread pitch on the holes is different from stock though. I found that out when i did a motor swap haha

I would highly doubt there has ever been any problems with the FM (Flyin Miata) kits of any stage. However, the real question is probably whether the cheap ebay "F1 Racing" clutch kits are worth the risk. Who makes em? SPEC?

Also, if I'm understanding the thread correctly, some people are playing it safe while still saving a few bucks by going with the ebay "F1 Racing" flywheel paired with a nice name brand clutch kit, right?

Thanks,
Robert

I would go with an Exedy or an FM clutch, not the F1 clutches.
Ebay F1 clutches have a bad rep... I'm not sure tho if this only applies to their puck clutches.

I noticed some hardened spots on the flywheel after I had to pull the tranny again. Little sealant was in between the rear main seal and the cranck, causing oil spill. So the clutch took some oil (again). Besides that it is all great. The engine revs a bit too easy making it weird to take off. I rev the engine too much, take my foot off the gas, letting the clutch go and put some throttle back on. As if I can't drive well at all. The engine does not stall easy though. Clutch feels like gripping good.

Thanks for the replies guys. I'm definitely not going to use an F1 Racing clutch, now, the next question is this, are the F1 Racing flywheels ok?

Thanks again,
Robert
