Well guys I just ordered my BBK L/T's, catted mid, and Spec Stage II clutch. The shop said that I will hear some chatter, and maybe a little whistling for the first 5-600 miles. I was told I can take it up to 4-5000rpm, but not to drop the clutch or do anything dumb with it until its had its break in period. How long did it take some of you guys with Specs for all the chatter and noise to ease up? Ill give it the 600 or so miles break in, just curious if it actually takes that long.
