My Dad put in my gears, he's a senior/master technician for Ford. We just let the car idle on the hoist for awhile in gear, then I drove easy around the parking lot and easy on the highway for about 20 minutes.

If you got the clutches replaced, I was told drive 50 miles at no more than 50mph then they will be broken in. If you didn't I heard theres no breakin period

I've also heard there's no break in period, but it wouldn't hurt to take it easy for a little bit at first.

yeah i cant afford to mess anything up, although the place that did it for me is warrantying everything for me so if something did happen they fix it for free, which is good

4.30's

Someone's not worried about traction.

Go out and drop the hammer. Should be fine.

My scientific break-in procedure:

1. Make sure the car moves
2. Listen for any wierd sounds coming from the rear end
3. With no sounds present proceed to step four
4. Get on the freeway and blast up 110 speed shifting like a maniac

Hasn't let me down yet...

Jake knows well! Put the car in first gear. Make sure there is no whining or clunking sound while letting the clutch out. If not, shift second and try the same thing. If there are no noises in low RPM second, your fine. Go out and give it hell.

After backing up, proceed forward. While dead stopped, rev the car to 4,000 rpm. Lightly come off the clutch, when it's almost engaged floor it. When the RPM reaches 5,500 rpm, slam 2nd. Reach the desired length in second and bang 3rd. You should have went in distance about a 1000 feet. Look in rearview mirror and gaze upon 800 feet of smoke. Gears are broken in now. Enjoy.

yeah i probably didnt make it a quarter mile on my last set of gears before i wound it up as tight as i could and dumped the clutch. there really shouldnt be a break in. just maybe see if it makes funny noises on your way out the drive way. after that. HAMMER IT!
