Just picked up my Lava 18 GT3 from Perimeter in Atlanta on Friday. I kept it under 4000 for the drive home which was about 550 miles. From here I'll follow AP's recommendation. Most likely do the first oil change at 2000 miles.
I did the 2000 mile mile max 4000 on my first 15 GT3 and the 2000 mile oil analysis looked pretty good. On a 10 GT3 broken in the same way the oil analysis showed 50 ppm of Cu at 9000 miles.
On my 16 GT4, not apples/apples, the break-in was from Perimeter to AMP where I spent the day on track. A little on the quick side. However, the oil analysis at 2000 miles was one of my best for a new car.

The gt3 engine spends a good amount of time on the Dyno before being put in the car

Brake in is for other components

No reason to change the oil

Wow that's awesome. What a difference. So basically up to 7,000rpm until 1,000mi then can let her rip. I've been shifting at 4k and just being teased with the open valves before I had to shift. I've got 550miles currently. Thanks for the updated manual. Mine is a 2018.

while attending PSDS in AL, I asked the staff about break in miles

they all kinda just laughed at me, and the notion....

Spoke to AP at Goodwood in 2017 and engine guys at Rennsport and they said warm it up, no launch control for the tranny, but vary the revs as much as possible up to whatever you as a driver are comfortable with. Compression braking the engine said the engine guy helps to seat the rings.

Easy for them to say...they are not paying for the cars they get to drive and can abuse them from day one and will get another if it breaks. I'll take my advice from the engineers who designed and built the cars.

I thought this too - but their fleet goes back through dealerships for sales....

What is the best motor oil?

What use would the Internet forums be without questions like these.

Not openly disclosed, buyer has to do their research. There was recently a yellow GT3 F/S well below MSRP and certainly looked like a pricing outlier, until you discovered it was a corporate car.

For same reason, BMW doesn't CPO any of their Performance Center cars once they are done with PCD duties...

Just hit my 1000 mile mark and ready to open her up!

I'm not concerned with doing an oil change at 1000 miles with these new engines, but there was another thread that mentioned the "break-in" service actually consists of unlocking the ECU. Has anyone actually confirmed this or seen any sort of performance gain after their first service?

not true there is no break in service. Service is 10000 miles or 1 year.

I feel that is a common 'myth' - there is no unlocking of ECU and miraculous performance gain, not for the GT cars anyway.

IIRC , there have been some cars where there was a software update after the first service/break in (IIRC last gen BMW M5), but that mostly had to do with babying the tranny during the break in (i.e. tq limiter in place)
