Ram Twin Disk ????
I have a 2000 FRC with a fully built 370, my Ram Twin Disk clutch is chattering fairly loud when the clutch is pushed in. It is almost to the point of getting embarrasing stares from onlookers. Is this normal? my other question is today i noticed at various times that the clutch is making a strange grinding noise that is pretty loud and sounds like something is rubbing wrong. Typically the noise only comes in nuetral and when i rev the car the noise goes away. Any thoughts on this would be great. i just bought the car about two weeks ago and so far i am completely in love with the. I have to say this car is quite alot more fun than my viper plus its a pretty inexpensive tuner car. I am in the Houston area and would like to get to know some vette fans around here.

My Mcleod dual (after 500 easy break in miles) drives like stock. No chatter at all. I really think that a proper break in is critical with dual disc clutches since you have twice as much surface area to mate in with each other.

Do you know if they used the steel pedestals or the composite ones when they put in the clutch? I can tell you that I have a ram and the chatter you described is actually the floater plate rattling. On mine and most applications with racing in mind you use the steel pedestals and those create the rattling with the floater when you press in the clutch pedal. They have some composite ones that pretty much eliminate the rattle you are hearing. As for the grinding I cannot really comment on that. I can say though that I really abuse my clutch and the ram twin in my car is going well after over 2 years so far.

You probably should have researched that clutch before you purchased and installed it. The sound you are hearing is floater-plate rattle (normal & common). In other words the steel plate in-between the two clutch disks is rattling on the "steel" pressure plate stands when the clutch is disengaged. The Ram Street dual clutch kit comes with steel and composite material pressure plate stands. The steel are obviously more durable, but the composite are provided to eliminate the audible rattle inherent with this clutch design.
With that said I installed half of each in an alternating fashion to compromise (3-steel, 3-composite). I'm sorry you did not know this before you installed you RAM street dual with all steel pressure plate stands. I have absolutely zero rattle with mine
.Solution: I have a set of composite PP stands for sale if you want to remove your clutch again to install them

Grinding velvet? That is a new one. It could be some kind of alteration in the friction surfaces of the clutch disks. How many regular break-in heat cycles have you gone through before going ***** out? You really need to break in this clutch slowly. The disk material used in the Street dual is not very aggressive (it's actually pretty soft). This was done to keep engagement close to stock, but still provide the outstanding holding force of a twin disk clutch. With that said the clutch disks (300 series compound) need to be heat cycled quite a few times under moderate driving conditions.

Interesting, so the mix will also reduce rattling? Whenever I get mine around to rebuilding I plan on swapping in some composite stands. I just wish they were available when they first made the clutch.
