So my clutch is slipping slightly at high rpm. It's a street ACT kit.
The SM has a 4 puck that I like.

Which 1.8 track only clutch?
And which bearings to go with it? OEM MAZDA?

I'll have the flywheel surfaced and check around for oil leaks.

 

949's twin disc? Does it have to comply with any rules?

 

ACT HD unsprung 6-puck ceramic here... On the street it's awesome.

 

I looked back at my order history and it's an ACT HD pressure plate with street disk. Rated 231lbft. My cheapest route would be to throw in the 4-puck unprung. It would jump to 300lbft.

The 949 is nice but rather spend that money on aero

Looking for info which bearings are best.

 

Rules of the wallet only

 

Who has done track time on a Clutch Master FX500?
Looking for options that are actually available here...

 

What do you mean bearings? through out and pilot? And what do you mean checked for oil leaks? your rear main seal?

I have the xtreem act and its held up fine for 3 years now on the track. I'm going with a twin now that the engine is out. My biggest complaint is rev matching the down shifts with the stock flywheel seems a bit lagy to me.

OEM pilot and through out bearing, and rear main seal with no problems.

 

Go with OEM throw out and pilot bearings. As for clutch, 949 twin, or a 6puck cerametallic plate with extreme PP.

 

Yes those. I remember reading about Chinaman crap but can't remember if that was what ACT included and if I should order OEM MAZDA gear to be safe.
My OEM flywheel has it's ring shaved off and it's fine. Clutch is 2 years old now and slipping. Not sure if it's worn or a leaking rear main. I suspect worn.

ACT is a bit hard to get around here and Clutch Master, Exedy and Spec I can get my hands on.

 

That is what I would do for the low cost option. I would then take the money saved and use it to have a shop machine off the weight ring on the stock flywheel (if your class allows it) and have the flywheel matched balanced with the pressure plate. Should not cost much.

 

ORDERED: Twin Ceramic!
This **** is so full of win.

 

You won't regret that. The ability to snap off gear changes as fast as you can move the shifter is fantastic.
