I put 1200 miles on my new exedy stage 2 clutch, about 600 stop and go miles. Last night I did my first launches on it and it slipped bad off my 6k two step I was wondering what people had luck with as far as break in miles? 5k launch seemed to help a bit but not much, and 4k just bogged. A 3010 clamping force should be doing alot more than it is. I just had a act stage 1 in the car previously and it bit alot harder. Is there still more break in period to be had on the exedy, could I have done any damage to the new clutch?

 

your clutch is fine, go back and get some more runs. Stop worrying about it.

 

should have just launched the heck out of it as soon as you put it in.

 

I never could believe or go with the hard break in period for a new clutch. That subject seems like a big arguement to me. 7 hard launches on it at mission last night should be a start then

 

Breaking it in is the right way to go.

However, even I launched the crap out of my first RPS twin carbon as soon as it was installed and it held up well!

slipped a little for the first few times and then it was fine!

 

Agree, beat on it out of the box. 500 mile break in maybee. Just heat cycle a few times before luanching.
