new stage 3 clutch question

[steve_mk3]

As part of my rebuild I replaced the clutch, resurfaced the stock flywheel and replaced the slave clyinder.

with less than 1 mile on it, when I engage the clutch the car shudders then starts to move.

Wondering if this is normal? How do you break in a clutch? the clutch engages about 3/4 of the way up, is that where it is supposed to be?

Thanks for your help!!

I have 300 miles on my Spec stage 2 and it chatters at low RPMs also. I think its normal for a higher performing clutch. Try revving the motor up more (2-2.5k) before letting the clutch out. When breaking in a clutch drive it real easy(no high RPM dumps or hard shifting) for about 500 miles. Then progressively get on it a little more till about 650 miles then you should be all broken in nice. Also, stop and go (city) driving is the best way to break in a clutch, it lets the disc and Flywheel form a nice "groove" together. *My mileage recomendations are probably in excess but its better to make sure than to have to replace a clutch pre-maturely.

i heard those same numbers for breaking in a clutch...actually i think those are universal numbers for any mods that effect the car as a whole....i.e. clutch, turbo, etc.....but im not positive

Only really need to break in two things that I can think of.

Clutch & Piston rings. Well, and to a lesser extent brake pads and new tires, but those are quick.

i broke in my clutchmasters stage III for a thousand miles before i got on it. i believe its recommended 500 miles of stop and go driving. so, to even it out, since where i live that would take forever, i just broke it in for a thousand miles (per dr. jonez's recommendations)

Thanks for the responses-
While you were breaking the clutch in, did the car shutter? My car shakes then starts to move. If I rev it to like 1500-2000 then slip it, it will engage much smother, but at like 1200 the damm thing shakes.

Yes, I've never found a puck style clutch that doesn't chatter.

I have had 2 stage 3's.. my one on the 7m chattered like crazy.. the 1jz one chatters but not nearly as much as my other one.. wierd.

After the 1K break in, my HPF bronze disk has NO shutter. It's silky smooth, and won't slip.
