Waiting 500 miles for the break in! It's killing me, I want to hammer it so bad, 250 more miles to go! Other than that, this clutch set up is wonderful, and would recommend it to anyone looking. Pricey, but well worth it IMO, that is all.
There are some out there with no required break in. I know the DFX when it came out was no break in and when I called fidanza about my 4.3 they said the same.
