i hope it does break in and quiet down
I dropped an email to Brenspeed and Spec inquire as to whether the chatter is normal during break in. Here are their responses:
I will agree that the Spec stage 2 will exhibit a substantial amount
idle "chatter" throughout it's break-in period. I have seen the
this disappear after the recommended time-frame. Keep in mind the stage
will probably always have some of that characteristic on the street do
it's power capacity.
Yes, it is. The extra clamp load from the plate and friction from the
Kevlar disc will increase the rate of engagement, so after you get used
it and it has some mileage to fully seat, it will get a little better.
(normally as its smoothest point by 1000 miles, though breakin takes
way before then) But it will never feel totally stock as it is built
handle over 600hp! Thanks,
Two Daves can't both be wrong! Lol.
Ohnoesaz- The flywheel must be resurfaced when installing a new clutch. There is no exception. I will get a picture of the bleeder for the clutch for you when the weather clears up down here and post it in this thread.
MustangGT0405- There was a small snafu with my whipple order caused by my credit card company, so my order didn't go through until yesterday. I'll let you know when it's in route.
I hope this thread has been helpful to those considering a SPEC clutch. It's too early for me to say definitively whether or not I'd recommend it, but I will say that Brenspeed has nothing but good things to say about SPEC, and so far they have NEVER steered me wrong.
