Whats a good break in for this car. Should I baby it, drive how I would normally or beat like I stole it. From what I understand these engines come broken in already. What's the majority ruling? Thanks

Take it easy for the first 500-600 miles, 1000 to be safe. Vary the RPM within that period.

Around 1,000 miles would be the normal period to break in an engine - no more than 4,000 rpm for the first 500 miles and then gently increase. That way your engine should stay quiet (not full of rattles) and oil tight.
 
Or...do what my neighbor does with his new Gallardo:

Starts it up, drives it cold beyond redline until it is sputtering and clanging.

Worked for him for almost two weeks.

Hmmm, wonder why I have not heard it go by lately.

I am tempted to ask "what is wrong with people?!" but I am not supposed to ask that.

New GT owner's common sense rules:

This is from an old post:

Some of "Jay's Laws":

1. Never "thrash" (drive hard) on a cold engine. Always wait until the water temperature is >160 F (in other word, approaches equalibrium). The moving components within the engine expand at different rates and therefore their proper clearances aren't established until then. Your GT engine has forged pistons which must be up to operating temperature before the proper piston to cylinder wall clearance is established.

2. The tranny will shift with some difficulty until warm, especially into second gear. Be gentle on it, as with time (about 2,000 miles or so) it will begin to shift more smoothly. Shift from 1st to 3rd (bypassing 2nd) or double-clutch if needed.

3. Stop-and-go city driving is a better way to break in a GT (this is my opinion, based on the transmission issues). Shift through all of the gears whenever possible which also operates the engine at many different RPM's.

4. Resist the urge to get too wild and crazy, give it some time to generate a good feel for the car. You have a lot of power here. Most GT (and other supercar) disasters occur during that "got to get in it quick and see what this baby can do" moment. This ain't no Yugo...

5. Be extra careful when backing up, due to very limited visibility. The front spoiler also needs consideration. The rear diffuser hangs fairly low, so be careful when going through nasty road bumps (I got nicked on day two...).

6. I make my auto detailer purchase cleaning supplies to be used on my car only (buffing wheels, polishing clothes. etc.). I wash them myself. I don't want someone else's dirty laundry being used on my car!

7. At the tire shop, I have my own personal replaceable plastic parts for their tire changing machine that are to be used only on my wheels. I paid for these parts and they swap them out temporarily for use on my car. Sure, it cost more, but I like to keep things clean.

8. Cold tires and cold and/or wet pavement can be a dangerous combo. Remember Roberto Guerrero in the beginning lap of the Indy 500, years ago? Your car has enough power to reproduce that maneuver!
